Best M&A Advisers in the UK (2026): London, Manchester and the Regions

Best M&A Advisers in the UK (2026): London, Manchester and the Regions

Quick answer: On dated 2025-26 adviser-of-record releases, the UK mid-market independents that lead a £5m-£250m sale are DC Advisory (nine dated UK-linked mandates, November 2025 to August 2026) and Alantra (nine, February 2025 to July 2026); in the accountancy-led tier, BDO UK and RSM UK publish dated sell-side releases and Grant Thornton appears in dated trade press. Cavendish has four site-verified UK offices (London, Edinburgh, Manchester, Birmingham) but thin dated evidence; Clearwater's UK business has been subject to a pending KeyCorp acquisition agreement since April 2026. Rothschild & Co and Houlihan Lokey are reference desks for larger deals; K3 Advisory Group, Marktlink and Benchmark International are volume houses for owner-managed businesses. The Financial Services Register was checked on 19 September 2026: DC Advisory (Daiwa Corporate Advisory Limited, FRN 175853), Alantra Corporate Finance LLP (FRN 478406), Cavendish Capital Markets Limited (FRN 467766), Clearwater Corporate Finance LLP (FRN 483062), Houlihan Lokey UK Limited (FRN 792919), N M Rothschild & Sons Limited (FRN 124451), BDO LLP (FRN 229378), Grant Thornton UK LLP (FRN 231791), the four Big Four LLPs and K3 Deal Advisory Capital Markets Limited (FRN 1009438) are authorised; RSM UK Corporate Finance LLP is licensed by the ICAEW as an exempt professional firm, not FCA-authorised; Marktlink, Benchmark International, KBS Corporate and Knight Corporate Finance are not on the register as an authorised firm, appointed representative or exempt professional firm, so ask which exclusion or exemption they rely on. On the law: Business Asset Disposal Relief has been 18% on the first £1 million of lifetime gains since 6 April 2026, EOT relief gained statutory conditions for disposals on or after 30 October 2024, the Takeover Code stopped applying to most private companies on 3 February 2025 (transition to 2 February 2027), and the National Security and Investment Act bites only in 17 defined areas at 25%, 50% and 75% thresholds. City guides: London and Manchester.

I'm Sean Yu, co-founder of Peony, a data room company. I have built and watched thousands of data rooms across my career: about 1,000 of those when I was an investor at two funds with a combined $6.3 billion in AUM, and the rest across the 6,800+ teams Peony serves today, where the founders we work with have raised over $18 billion to date. Peony's registered office is at 86-90 Paul Street in London, and my own path ran through M&A at Nomura, venture at Backed VC and growth equity and secondaries at Target Global, so the UK adviser market is one I have sat across the table from on both sides.

Here is the honest read. Every "best M&A advisers UK" list I could find this year reprints a league table that rewards small-deal volume, lists bulge-bracket names that will not return a £20 million call, or is a business transfer agent's own page. None tells you which firms publish dated deals with a named counterparty, which entity is actually on the FCA register, or what changed in the tax code in April. This guide does those three things and routes you to the city guide that owns your bench.

The playbook: under roughly £5 million of enterprise value, a regional team or volume house with a named partner; £5 million to £100 million, a London independent or accountancy-led team against a regional house, picked on dated sector deals; above that, or with a foreign buyer pool, the London desks. This page sits above London and Manchester, beside our Canada guide, under the master hub, Best M&A Advisors.

What is the 2026 UK M&A backdrop, and why does it change adviser selection?

The buyer who pays for a UK company in 2026 is usually foreign, and the domestic bidders who used to supply the competitive tension are about half as numerous as a year ago. Both facts come from the Office for National Statistics.

The ONS bulletin Mergers and acquisitions involving UK companies: April to June 2026, released on 1 September 2026, counts completed transactions worth £1 million or more that changed ultimate control of the target (ONS). The provisional figures: 353 such deals in Q2 2026, down from 407 in Q1; inward M&A (foreign companies acquiring UK companies) worth £25.4 billion, up from £15.7 billion in Q1, across an estimated 162 deals (203 in Q2 2025); domestic M&A worth £4.2 billion across an estimated 130 deals, against 241 in Q2 2025; outward M&A £2.7 billion across 61 deals. The bulletin quotes the Bank of England's Agents' June 2026 summary that investment intentions had become more subdued since the Iran conflict.

Two readings follow. I call the first the Foreign-Buyer Value Gap: inward value was about six times domestic value in the quarter, so the cheque at the top of the market is written from abroad, by exactly the buyers the National Security and Investment Act screens. The second is the domestic count, 241 deals in Q2 2025 to 130 in Q2 2026, a fall of about 46%: those are the deals owner-managers actually do, and an adviser whose buyer list is a UK-only spreadsheet is selling into the half of the market that shrank.

One honesty note: there is no reliable published UK adviser-level dataset that ranks firms on value for the £5 million-£250 million band. The volume league tables that circulate (Experian MarketIQ, LSEG) reward count, so I have printed no table from them, only each firm's own dated release or a dated trade-press headline.

Which M&A advisers actually cover the UK mid-market in 2026?

Thirteen names in four tiers: the UK mid-market independents, the accountancy-led corporate finance benches, two large-cap reference desks, and three volume houses for owner-managed businesses. Sector specialists, public-company brokers and the regional firms that own the city benches are in the leave-off section, with reasons.

How did we rank these firms?

On dated adviser-of-record evidence first, footprint second, brand last. A firm's own dated release naming itself as adviser on a named transaction is the strongest evidence a seller can check without a subscription; a dated trade-press headline is next; an undated logo wall is footprint, not evidence. Only DC Advisory, Alantra, BDO UK and RSM UK carry 2025-26 own-release evidence here; Grant Thornton and PwC carry dated trade press; Rothschild & Co carries own releases at a scale that is the wrong desk for most readers; Cavendish, Clearwater, Marktlink, Benchmark and Houlihan Lokey are listed on footprint and marked as such. Every deal is printed as announced unless a completion source exists.

On regulation: the Financial Services Register was opened on 19 September 2026 for every firm on this page, and each row below prints the outcome: the registered name and firm reference number where the entity is FCA-authorised, the ICAEW exempt-professional-firm status where that is the lawful route, and a plain "not on the register" where no authorised, appointed-representative or exempt-professional record exists. The register often differs from the brand on the footer, and three of the thirteen rows are not on it at all. Repeat the check before you sign, because statuses change and it is your money.

1. DC Advisory

• Where it sits: the Daiwa-owned mid-market bank (Daiwa Corporate Advisory Limited) with the deepest dated 2025-26 UK release wall of any firm here. Its site blocked automated reading, so every deal fact is from its own dated press-release headlines.
• Dated UK mandates (announced): adviser to OMERS Private Equity on the sale of Network Plus to Warburg Pincus (30 June 2026); adviser to LDC on the sale of Wifinity to Arcus Infrastructure Partners (9 January 2026); adviser to Perwyn on the sale of Lowe Rental to MML Keystone (10 November 2025); six more in the ledger below. Its own 18 February 2026 release says it ranked top three globally for mid-market industrials M&A in 2025, the firm's statement of its own ranking.
• Registration: Financial Services Register (checked 19 September 2026): Daiwa Corporate Advisory Limited, trading as DC Advisory, FRN 175853, authorised since 1 December 2001, corporate finance business only. There is no entity named DC Advisory Partners on the register.
• Verdict: the first call for a £20 million-£250 million UK company whose likely buyers are sponsors and their platforms, and the evidence format every other adviser should be asked to match.

2. Alantra (UK)

• Where it sits: the UK arm of the Madrid-listed Alantra Partners S.A.; the UK business grew out of Catalyst Corporate Finance.
• Dated UK mandates (announced, own releases): adviser to Birmingham-based Joblogic and Axiom Equity on their growth investment from Vista Equity Partners (18 September 2025); adviser to Mornington Partners on the sale of Rock Compliance to Andwis (28 February 2025); adviser to J.C. Flowers & Co. on the acquisition of Pepper Advantage from KKR (21 November 2025); six more in the ledger, including the July 2026 Volta Data Centres agreement for Arcus.
• Registration: Financial Services Register (checked 19 September 2026): Alantra Corporate Finance LLP, FRN 478406, authorised since 1 July 2008, corporate finance business only, registered at 25 Cannon Street, London. The register also carries a clone warning for an unauthorised "Alantra Capital / Alantra Global", so match the entity name on the engagement letter.
• Verdict: the co-first call with DC Advisory for a £10 million-£150 million software, services or consumer company, and the one independent here with dated Midlands evidence.

3. BDO UK Corporate Finance

• Dated UK sell-sides (own releases): Templant Hire Limited to Camfaud Concrete Pumps Ltd (31 March 2026); Saltire Facilities Management Ltd to Daikin UK (22 July 2025; a Scottish target); Colpac Limited to Sabert Corporation (4 August 2025). Insider Media (17 January 2026) reported more than £2.5 billion of BDO deals across the Midlands and East of England in 2025, and Scottish Financial News (23 January 2026) £1.5 billion for BDO Scotland.
• Registration: Financial Services Register (checked 19 September 2026): BDO LLP, FRN 229378, authorised since 23 December 2003; there is no separate BDO corporate finance entity on the register, so the corporate finance team's permissions sit inside the LLP.
• Verdict: the right call for a £5 million-£75 million manufacturing, facilities or packaging business outside London when you also want vendor due diligence in the same building; ask who issues the numbers and who runs the process, because BDO sells both.

4. RSM UK Corporate Finance

• Dated UK sell-sides: The Health & Safety Group (own release, 1 April 2026; buyer not named); Charles Saunders to Kitwave, the AIM-listed wholesaler (Consultancy.uk, 3 August 2026); Gloucestershire-based care homes (Consultancy.uk, 11 September 2025).
• Registration: Financial Services Register (checked 19 September 2026): RSM UK Corporate Finance LLP is licensed by the ICAEW under the Designated Professional Body regime and listed on the FCA register as an exempt professional firm, not FCA-authorised, so it carries no firm reference number; that is a lawful route for accountancy-led corporate finance, and the register notes that the Financial Ombudsman and FSCS are unlikely to apply.
• Verdict: a solid second interview for a £5 million-£50 million services, food-distribution or care business, with the same numbers-versus-process question as BDO.

5. Grant Thornton UK Corporate Finance

• Dated UK sell-sides (trade press): Templegate Electrical Supplies Limited (Business News Wales, 8 April 2026); Chestnut Nursery Schools to AcadeMedia (Consultancy.uk, 24 June 2026); RJ Power to Ipsum (Consultancy.uk, 9 July 2025).
• Registration: Financial Services Register (checked 19 September 2026): Grant Thornton UK LLP, FRN 231791, authorised since 1 July 2004; since the February 2025 split the advisory practice sits in Grant Thornton UK Advisory & Tax LLP, FRN 1024656, an appointed representative of Grant Thornton UK LLP since 27 February 2025, so ask which of the two entities signs your engagement letter.
• Verdict: the accountancy bench with the widest regional evidence trail (Wales, the North, education, electrical distribution); a natural third interview for a regional owner.

6. Cavendish

• Where it sits: the AIM-listed group formed from finnCap and Cenkos, a full-service investment bank for public and private companies whose footer lists four UK offices (London, Edinburgh, Manchester and Birmingham; Business Live reported the Manchester opening in November 2024) and whose services run from sponsor, nomad and broking to M&A sell-side.
• Dated evidence: thin. Cavendish lists Ariya Neuro Care on its deal wall, and Freeths, the sellers' lawyers, announced the sale to Choice Care on 7 May 2026; the rest of the wall is undated.
• Registration: Financial Services Register (checked 19 September 2026): Cavendish Capital Markets Limited, FRN 467766, authorised since 31 July 2007; the listed parent, Cavendish Financial plc, is the unregulated holding company, so the engagement letter should come from the Capital Markets entity.
• Verdict: listed on footprint, not on dated evidence. The right interview for an owner weighing a listing against a sale; ask for three dated private M&A completions first.

7. Rothschild & Co (including Arrowpoint Advisory)

• Where it sits: the large-cap reference desk, with FTSE-scale 2026 UK releases: lead financial adviser to Associated British Foods on its roughly £15 billion demerger of Primark and FoodCo (21 April 2026, announced) and financial adviser to McCormick on its combination with Unilever Foods (31 March 2026, announced and pending). Private Banker International (30 July 2026) reported GlobalData's H1 2026 tables placing it first among Europe M&A advisers by volume.
• The mid-market arm: Insider Media and Consultancy.uk (6 and 7 May 2025) reported a North West mid-market team under the Arrowpoint Advisory brand, led from Manchester by Shahbaz Qasim; no dated Arrowpoint deal is captured here.
• Registration: Financial Services Register (checked 19 September 2026): N M Rothschild & Sons Limited, FRN 124451, authorised since 1 December 2001, with Arrowpoint Advisory recorded as its trading name since 7 July 2022; the former Arrowpoint Advisory LLP (FRN 400968, the renamed Livingstone Partners LLP) has not been authorised since 21 November 2022, and the register carries clone warnings against the Rothschild name, so match the FRN.
• Verdict: wrong desk for a sub-£50 million owner-managed sale; relevant above that, and in Manchester through Arrowpoint if the team shows its own completions.

8. Clearwater (UK)

• Where it sits: one of the larger independent UK mid-market houses, Birmingham-based (Consultancy.uk, 15 December 2025), with an ownership change under way: KeyCorp, parent of KeyBanc Capital Markets, announced in April 2026 an agreement to acquire Clearwater's UK business, and its Form 10-Q for the quarter ended 30 June 2026 (filed 4 August 2026) still described it as an announced agreement, so the deal was pending at that date. The continental Clearwater International business is separate.
• Dated evidence: none with Clearwater's role stated in a 2025-26 UK headline; its site is walled, so check the current brand before you engage.
• Registration: Financial Services Register (checked 19 September 2026): Clearwater Corporate Finance LLP, FRN 483062, authorised since 24 July 2008, corporate finance business only; the register's head office is 10 Livery Street, Birmingham, which matches the base above.
• Verdict: listed on footprint and reputation, with a mandatory caveat: ask who will own the firm at your completion date and whether the partner pitching you is staying.

9. Big Four corporate finance (Deloitte, KPMG, PwC, EY)

• Where they sit: integrated corporate finance inside the audit firms, selling lead advisory alongside vendor due diligence, tax structuring and quality of earnings; strong on numbers and acquirer relationships, weak on attention for a £10 million seller. Financial Services Register (checked 19 September 2026): each LLP is directly authorised and there is no separate corporate finance entity for any of them, so the deal team's permissions sit inside the audit firm: Deloitte LLP (FRN 213218), KPMG LLP (FRN 210513), PricewaterhouseCoopers LLP (FRN 221411) and Ernst & Young LLP (FRN 196203).
• Dated evidence and verdict: Private Banker International reported on 27 April 2026 that GlobalData's Q1 2026 tables placed KPMG first among Europe M&A advisers by volume; Consultancy.uk reported PwC supporting Bluesky on its sale to Woolpert (3 June 2025) and advising alongside PKF Smith Cooper on a SEND education deal (15 May 2025); nothing surfaced for Deloitte or EY. The numbers bench for a £50 million-plus sale with a complex tax structure or a carve-out; ask which partner runs the process and whether the same firm audits your likely buyer.

10. Houlihan Lokey (UK)

• Where it sits: one of the largest mid-market advisers in London, and the volume leader in GlobalData's 2025-26 M&A adviser tables as reported by Private Banker International (global, 21 April 2026; North America, 30 July 2026; financial services, 3 August 2026). None is a UK table. Financial Services Register (checked 19 September 2026): Houlihan Lokey UK Limited, FRN 792919, authorised since 1 May 2018, corporate finance business only; six legacy vehicles including Houlihan Lokey (Europe) Limited are no longer authorised and an unauthorised clone entry uses the name, so match the entity.
• Dated evidence and verdict: HL's own transaction pages list 2026 pairings such as CorpAcq and TDR Capital (17 June 2026) and MASECO and Creative Planning (26 March 2026) without stating which side it advised, so I do not. One 2026 UK headline shows HL on a public deal without stating the side: Addleshaw Goddard's 4 March 2026 release says it advised Houlihan Lokey on the cash offer for Augmentum Fintech plc, which a Verdane-controlled bidder acquired for £185.7 million (scheme sanctioned 11 May 2026; Verdane announced completion on 14 May 2026). A reference desk for £100 million-plus sponsor processes; ask HL which party it advised, and for UK completions with the side stated.

11. K3 Advisory Group (KBS Corporate and Knight Corporate Finance)

• Where it sits: the highest-volume UK business-sales group, by its own account: KBS Corporate's site states that KBS Corporate Sales Ltd is a subsidiary of Bolton-headquartered K3 Advisory Group Limited, founded in 1998, floated on AIM in 2017 and acquired by Sun European Partners in 2023, with more than 1,200 professionals and 25 regional offices.
• What it publishes: K3 states that Experian MarketIQ ranked it the No.1 UK adviser by volume for the first half of 2026 (KBS release, 2 September 2026) and that it has led LSEG's annual statistics since 2017; those are self-reported volume ranks, and volume rewards small-deal count. Its technology boutique, Knight Corporate Finance (Manchester and London), publishes dated deals: adviser to CityFibre on its sale of Entanet to Virtual1 founder Tom O'Hagan (11 September 2026, completed).
• Registration: Financial Services Register (checked 19 September 2026): the group's authorised entity is K3 Deal Advisory Capital Markets Limited, FRN 1009438, authorised since August 2024, corporate finance business only; K3 Advisory Group Limited has no record of its own, and KBS Corporate Sales Ltd and Knight Corporate Finance Limited are not on the FCA register as an authorised firm, appointed representative or exempt professional firm when we checked on 19 September 2026, so ask the firm which exclusion or exemption it relies on and which entity signs the engagement letter (what that means).
• Verdict: the volume option for a £1 million-£10 million owner-managed business that wants a marketed process rather than a curated buyer list; Knight is a genuine technology boutique inside the group.

12. Marktlink (UK)

• Where it sits: a Dutch-headquartered mid-market adviser for owner-managed businesses whose UK contact page lists offices in Birmingham, London, Nottingham and Manchester, with a Manchester-code UK telephone number; the group opened its 22nd European office in February 2026 (Consultancy.eu, 4 February 2026).
• Evidence, registration and verdict: no dated UK deal captured, and Marktlink is not on the FCA register as an authorised firm, appointed representative or exempt professional firm when we checked on 19 September 2026; ask the firm which exclusion or exemption it relies on (what that means). Listed on footprint; a reasonable interview for a £5 million-£30 million Midlands or North West owner who wants a continental buyer list, and ask for three dated UK completions.

13. Benchmark International (UK)

• Where it sits: a global sell-side house whose live site lists Manchester and Oxford as its UK offices, alongside Tampa, Austin, Nashville, Denver, Los Angeles and European and South African offices. It is not headquartered in Birmingham, whatever older lists say. Its tombstones use its own phrase, "successfully facilitated the transaction".
• Evidence, registration and verdict: its homepage lists UK-relevant transactions such as Thermal Detection Limited and Thundercat Industries Limited without dates, carries no FCA statement, and Benchmark International is not on the FCA register as an authorised firm, appointed representative or exempt professional firm when we checked on 19 September 2026 (its only register history is an introducer appointed-representative link to St. James's Place that ended on 12 May 2022); ask the firm which exclusion or exemption it relies on (what that means). The second volume option for a £2 million-£20 million owner-managed business; ask what "facilitated" meant on the last three deals.

Which dated 2025-26 deals put these advisers on the record?

The table is the evidence behind the ranking, newest first. Every row is the headline of the firm's own release unless the status says trade press; announced means announced, not closed, and no value is printed except the one in Rothschild's own headline.

What the table omits is as telling: no dated 2025-26 UK headline with the adviser's role stated for Clearwater, Cavendish (Ariya Neuro Care is inferred from its deal wall plus the sellers' lawyers' announcement), Marktlink, Benchmark, Houlihan Lokey, Lazard, Evercore, Deloitte or EY, which is why those rows are ranked on footprint.

Who did we leave off, and why?

Six categories, each with a checkable reason.

• Sector specialists that belong in the London guide. Arma Partners, the London software boutique, is on the Financial Services Register as Arma Partners LLP, FRN 454270 (checked 19 September 2026), and publishes a dated deal wall (adviser to Finastra on the sale of its Universal Banking division to Pollen Street Capital, June 2026); GP Bullhound publishes exact-dated technology deals (Origo's sale to iPipeline, 1 September 2026) and is authorised as GP Bullhound Corporate Finance Ltd, FRN 915053, the earlier GP Bullhound LLP being no longer authorised; ICON Corporate Finance is authorised as ICON Corporate Finance Limited, FRN 231285, with its registered head office in Bristol, and works only in technology. Right calls for a software seller, wrong rows for a generalist bench; see the London guide and our software M&A advisers hub.
• Public-company brokers and nominated advisers. Peel Hunt, Panmure Liberum, Zeus and Shore Capital serve listed companies, and all four were confirmed on the Financial Services Register on 19 September 2026: Peel Hunt LLP (FRN 530083); Panmure Liberum Limited (FRN 403721, principal to the appointed representative Panmure Liberum Cambridge Capital Limited, FRN 1022870); Zeus Capital Limited (FRN 224621, Manchester head office), which also states that it is approved as a nominated adviser by AIM, an Exchange matter the register does not show, and publishes private M&A roles; and Shore Capital and Corporate Limited (FRN 146629, the corporate finance arm), beside which the register carries two unauthorised Shore Capital clone warnings. A nomad appointment is a duty to the Exchange and the listed company, not a sell-side mandate for shareholders. Cavendish made the list because its verified footprint and services span both lanes.
• Bulge names without dated UK evidence. Lazard and Evercore: no dated 2025-26 UK advisory headline was captured for either, so I do not rank them; both are FCA-authorised (Lazard & Co., Limited, FRN 114054; Evercore Partners International LLP, FRN 532714), and the register carries clone warnings against both names.
• Regional accountancy-led corporate finance. Azets, FRP Corporate Finance (the former Spectrum Corporate Finance domain now redirects to FRP Advisory; the FCA-authorised M&A arm is FRP Corporate Advisory Limited, FRN 716736), PKF Smith Cooper, Saffery, Hazlewoods, Dow Schofield Watts, HURST and Cowgills are real teams with real deals and belong on the city benches. Dow Schofield Watts' corporate finance entities, Cowgills Corporate Finance Limited and HURST Accountants Limited are each licensed by the ICAEW under the Designated Professional Body regime and listed on the FCA register as exempt professional firms, not FCA-authorised (checked 19 September 2026). HURST joined the Dains Group on 27 January 2026; Beever and Struthers merged into Menzies on 4 August 2025 and is an audit house, not a sell-side adviser. See the Manchester guide.
• Name traps. Cavendish Maxwell is a Dubai property consultancy, not Cavendish. Spectrum Corporate Finance's site now forwards to FRP. Catalyst Corporate Finance is Alantra. K3 Capital Group is the former listed name of K3 Advisory Group.
• Business transfer agents with no footer, no dates and a cold email. The category is legal, because arranging an asset sale can sit outside the FCA perimeter article that catches share sales. I name none; no FCA line, no dated completions and no named partner means no engagement letter.

Which UK city guide should you read next?

The city guides own the benches that actually staff a £5 million-£50 million regional sale.

London

Every national desk on this page is London-led, so the London guide is where DC Advisory, Alantra, Cavendish, Rothschild & Co and Houlihan Lokey appear again with their London evidence. What it adds: the software specialists (Arma Partners, GP Bullhound, ICON Corporate Finance) with their dated deal walls; the public-markets tier (Zeus, Shore Capital, Panmure Liberum, Peel Hunt); the London deal engines in fintech, software, business services, consumer and healthcare, with both sides of a transaction on record (Uncovered's sale to LBG Media in June 2026 had GP Bullhound on the sell side and Zeus on the buy side); and an honest count of which London rows carry dated evidence and a register-checked FCA status.

Manchester and the North West

Manchester is the one UK region outside London with a bench deep enough for its own guide, and the Manchester guide ranks it on primary evidence: Dow Schofield Watts (Koto's acquisition of Stereo Creative, 14 September 2026), Knight Corporate Finance (Entanet, 11 September 2026), GP Bullhound's Manchester office (Zuto, 19 November 2025), HURST Corporate Finance (Wilkinson Cowan Partnership to Roger Hannah, 26 May 2026) and Cowgills Deal Advisory (GreenThumb to KEYTO Group). It also carries the "Manchester is being bought into" spine: Cavendish's Manchester office, Rothschild's Arrowpoint North West team and KeyCorp's pending agreement for Clearwater UK, alongside the consolidation that took HURST into Dains and Beever and Struthers into Menzies.

Birmingham, Leeds, Scotland, Wales, Bristol and Northern Ireland

No city guide yet, and I would rather say so than invent one. Two examples of what the national firms evidence: in Birmingham and the Midlands, Alantra's Joblogic mandate, BDO's reported £2.5 billion-plus of Midlands and East of England deals in 2025, Clearwater's registered Birmingham head office and Marktlink's and Cavendish's Birmingham offices; in Scotland, BDO Scotland's reported £1.5 billion of 2025 deals, the Saltire Facilities Management sale to Daikin UK and Cavendish's Edinburgh office. In each region, ask the national firm's local team for its own dated completions, not the firm's national list.

How do UK tax and law change a business sale?

Seven rules, each read from the statute or the responsible body's own page in September 2026. Model them with a UK tax adviser and deal counsel before heads of terms; the 2024 guidance still circulating is wrong on the first two.

Business Asset Disposal Relief: 18% since 6 April 2026 on the first £1 million

HMRC's guidance states the schedule: BADR means you pay tax at 18% on qualifying gains disposed of from 6 April 2026, 14% between 6 April 2025 and 5 April 2026, and 10% on or before 5 April 2025 (gov.uk, Business Asset Disposal Relief). The lifetime limit is £1 million, set by section 169N(4) of the Taxation of Chargeable Gains Act 1992, which applies the reduced rate only to so much of the aggregate qualifying gains as does not exceed £1 million (legislation.gov.uk, TCGA 1992 s.169N). Non-qualifying gains are taxed at 24% for a higher or additional rate taxpayer for disposals from 30 October 2024, and at 18% within the basic rate band. The conditions: for at least two years before you sell, the company must be your personal company (at least 5% of the shares and voting rights, and at least 5% economic entitlement), you must be an employee or office holder, and the company must be trading.

The arithmetic: the relief is worth 6 percentage points (18% against 24%) on the first £1 million of lifetime qualifying gains, so the maximum lifetime saving is £60,000, against £100,000 under the 14% rate and £140,000 under the 10% rate. A £5 million gain to a higher-rate taxpayer with the full £1 million available costs £180,000 plus £960,000, £1,140,000 in all (22.8% effective); a year earlier it cost £1,100,000. I call this the BADR Ceiling: the relief now moves the needle by at most £60,000 on any sale, so structure, price and the buyer list decide what you keep.

The Substantial Shareholding Exemption for corporate sellers

If a holding company sells the trading subsidiary, the gain can be exempt in full under Schedule 7AC to TCGA 1992. Paragraph 8 defines a substantial shareholding as not less than 10% of the ordinary share capital with 10% of distributable profits and winding-up assets, and paragraph 7 requires it to have been held throughout a twelve-month period beginning not more than six years before the disposal, in a trading company or trading group (legislation.gov.uk, TCGA 1992 Sch 7AC Part 2). It is not 10% for 24 months, a figure that still circulates.

Share sale or asset sale: stamp duty, TUPE and the planned Securities Transfer Tax

Three statutory reasons UK mid-market deals are overwhelmingly share sales. First, the transfer tax is the buyer's and it is small: when you buy shares you usually pay a tax or duty of 0.5%, as stamp duty on a stock transfer form for transactions over £1,000 or as Stamp Duty Reserve Tax on an electronic transfer (gov.uk, Tax when you buy shares). Second, HMRC's policy paper of 13 July 2026 states that a single, self-assessed Securities Transfer Tax will replace stamp duty and SDRT, with the government aiming to introduce it in 2027 through Finance Bill 2026-27 and an update on commencement this autumn (gov.uk, Securities Transfer Tax policy paper); no rate is stated and the 0.5% stamp duty has not been abolished, so a 2026 completion is stamped the old way. Third, TUPE: regulation 3 of the Transfer of Undertakings (Protection of Employment) Regulations 2006 applies where an undertaking situated in the United Kingdom transfers as an economic entity that retains its identity (legislation.gov.uk, TUPE 2006 reg 3). A share sale changes the owner of the employer, not the employer, so TUPE is not triggered; an asset sale transfers the undertaking, so employees move on existing terms with information and consultation duties attached.

Employee Ownership Trusts after Finance Act 2025

The EOT relief treats a qualifying disposal of a controlling interest to an employee-ownership trust as made for no gain and no loss, the 0% capital gains tax headline. Finance Act 2025, section 31 and Schedule 6, set conditions for disposals made on or after 30 October 2024 (legislation.gov.uk, FA 2025 Sch 6): the trustees must be resident in the United Kingdom at the disposal and for the rest of that tax year; fewer than 50% of the trustees may be excluded participators and excluded participators must not control the settlement; the trustees must have taken all reasonable steps to secure that the consideration does not exceed market value and that interest on deferred consideration does not exceed a reasonable commercial rate; the clawback window is now any of the first four tax years after the tax year of disposal; and the claim must state the number of employees and the consideration, including amounts due after the disposal. The practical point: an EOT pays market value over years out of the company's profits, so you are its creditor and your relief is exposed for four tax years, while a trade sale pays cash at completion; the two routes need different advisers, so decide first.

The Takeover Code after 3 February 2025

Most owner-managed private companies were never in scope, and since 3 February 2025 the remaining private and unquoted public companies have been leaving it. The Takeover Panel's scope page states that the Code now applies to a UK registered company if any of its securities are admitted to trading on a UK regulated market, a UK multilateral trading facility or a Channel Islands or Isle of Man exchange, or if its securities were UK quoted on or after 3 February 2025 and ceased to be within the previous two years (Takeover Panel, Companies to which the Code applies). Before that date, certain private companies were caught for ten years after they had been quoted, had shares marketed under section 693(3)(b) of the Companies Act 2006 or had filed a prospectus. Companies in scope on 2 February 2025 are transition companies until no later than 2 February 2027, so a formerly quoted private company or an unquoted plc should confirm its position with counsel before going to market; shares traded on a private platform such as PISCES do not bring a company into scope by that fact alone. Our hostile takeover explainer covers the mechanics when the Code does apply.

The National Security and Investment Act

The Act came into force on 4 January 2022 and is administered by the Investment Security Unit in the Cabinet Office, with the Chancellor of the Duchy of Lancaster as decision maker (gov.uk, NSI Act guidance, last updated 15 July 2026). If you are selling a qualifying entity in one of 17 defined sensitive areas and the buyer's shareholding or voting rights cross the 25%, 50% or 75% threshold, the acquisition is notifiable and needs approval before completion; completing without approval makes it void. The 17 areas are Advanced Materials, Advanced Robotics, Artificial Intelligence, Civil Nuclear, Communications, Computing Hardware, Critical Suppliers to Government, Cryptographic Authentication, Data Infrastructure, Defence, Energy, Military and Dual-Use, Quantum Technologies, Satellite and Space Technologies, Suppliers to the Emergency Services, Synthetic Biology and Transport. Outside them notification is voluntary, material influence is never mandatory, and the government retains a call-in power. Review runs up to 30 working days from acceptance of a notification; if called in, a 30-working-day initial assessment can be extended by 45. A civil penalty can reach 5% of global turnover or £10 million, whichever is greater.

The seller's job is the 17-Area Check: before the teaser goes out, your adviser and counsel decide whether the company is a qualifying entity in any of the 17 areas, because a software supplier to the emergency services, an engineering firm with a defence sub-contract or a data-centre operator may be caught when its owner assumes it is not; the buyer most likely to pay in 2026 is also the buyer most likely to need a filing.

W&I insurance

Warranty and indemnity insurance is a buy-side policy that pays for losses from breaches of the seller's warranties in the share purchase agreement, which lets the seller's liability be capped at a nominal amount and the proceeds leave escrow at completion; it is common on private-equity-led UK mid-market deals. The insurer excludes known issues, so everything found in diligence and everything in the disclosure letter falls outside the cover, which means the data room and the disclosure exercise define what is insured. No premium, retention or adoption figure is verified for this guide, and I print no rule of thumb.

What does FCA authorisation mean for a UK M&A adviser, and how do I check it?

Arranging deals in investments is a specified kind of activity under article 25 of the Financial Services and Markets Act 2000 (Regulated Activities) Order 2001: making arrangements for another person to buy, sell, subscribe for or underwrite a particular investment which is a security (legislation.gov.uk, RAO art. 25). Shares in a private limited company are a specified investment, so an adviser who arranges the sale of your shares needs authorisation, appointed-representative status or an applicable exclusion.

The appointed-representative route is why some mid-market advisers are not directly authorised: the FCA states that an AR carries on regulated activity under the responsibility of an authorised principal, which must make sure the AR is fit and proper and complies with the FCA's rules, notify the FCA at least 30 days before the appointment and review each AR at least every 12 months (FCA, Appointed representatives and principals). The third status is structural: a firm that arranges asset sales rather than share sales, or only makes unregulated introductions, may sit outside article 25 altogether; that is an observation about the perimeter, not about any named firm, and it is why some business transfer agents steer owners toward asset deals that cost the seller BADR and the buyer a TUPE process.

I call the check the Footer-to-Register Test: read the footer for the entity name and any firm reference number; search that entity on the Financial Services Register at register.fca.org.uk; confirm the status reads authorised or appointed representative and the permissions include arranging or advising on investments; and match the entity to the one that will sign your engagement letter. On 19 September 2026 I ran every firm named on this page through the register, and the outcomes fall into three groups: FCA-authorised with an FRN (DC Advisory as Daiwa Corporate Advisory Limited 175853, Alantra Corporate Finance LLP 478406, Cavendish Capital Markets Limited 467766, Clearwater Corporate Finance LLP 483062, Houlihan Lokey UK Limited 792919, N M Rothschild & Sons Limited 124451 trading as Arrowpoint Advisory, BDO LLP 229378, Grant Thornton UK LLP 231791 with Grant Thornton UK Advisory & Tax LLP 1024656 as its appointed representative, Deloitte LLP 213218, KPMG LLP 210513, PricewaterhouseCoopers LLP 221411, Ernst & Young LLP 196203, K3 Deal Advisory Capital Markets Limited 1009438, Arma Partners LLP 454270, GP Bullhound Corporate Finance Ltd 915053, ICON Corporate Finance Limited 231285, Peel Hunt LLP 530083, Panmure Liberum Limited 403721, Zeus Capital Limited 224621, Shore Capital and Corporate Limited 146629, FRP Corporate Advisory Limited 716736, Lazard & Co., Limited 114054 and Evercore Partners International LLP 532714); ICAEW Designated Professional Body exempt professional firms listed on the register without an FRN and not FCA-authorised (RSM UK Corporate Finance LLP, Dow Schofield Watts' corporate finance entities, Cowgills Corporate Finance Limited, HURST Accountants Limited); and not on the register as an authorised firm, appointed representative or exempt professional firm (Marktlink, Benchmark International, KBS Corporate Sales Ltd, Knight Corporate Finance Limited), which is not an accusation, because unregulated intermediation is common and can be lawful, but is a question to put to the firm in writing. The register also showed three things a footer does not: the registered name often differs from the brand (DC Advisory, GP Bullhound, Houlihan Lokey, FRP), legacy vehicles carrying the same brand are marked no longer authorised (Houlihan Lokey (Europe) Limited, GP Bullhound LLP, the former Livingstone Partners LLP that became Arrowpoint Advisory LLP and lost authorisation on 21 November 2022), and clone warnings sit beside the real entries for Shore Capital, Alantra, Lazard, Evercore, Rothschild and Houlihan Lokey, so match the FRN, not the name.

What do UK M&A advisers charge, and what does the only dated European survey say?

UK advisers do not publish rate cards, so the only dated evidence is the Firmex Europe M&A Fee Guide 2024-25, published in May 2025 from a survey of 456 middle-market M&A professionals in December 2024 and January 2025, of whom 289 were European advisers, with Germany, the United Kingdom and Switzerland the largest groups (Firmex, Europe M&A Fee Guide 2024-25). Its figures are in US dollars and pan-European, so treat them as a range, not a UK table, and do not mix them with the US edition in our M&A adviser fees guide, which says something different about direction.

Success fees. Averages ran from 4.3% on a $5 million deal, 3.6% at $10 million, 3.0% at $20 million, 2.3% at $50 million and 1.7% at $100 million, to 1.6% at $150 million, and at nearly every deal size fee levels were lower in 2024 than in 2023, with the largest drop on smaller deals. The most common structure, used by 40% of firms, was the Lehman formula: in its classic version 5% on the first $1 million, 4% on the second, stepping down to 1% on everything above $5 million; 22% used an accelerating ratchet (up from 16%) and 26% a flat percentage. More than three-quarters write a minimum success fee into the engagement letter, and 35% impose a break-up fee where the client rejects a bona fide offer.

Retainers and expenses. Monthly work fees were the most common structure (31% of firms), fixed fees second (25%), and 12% charged no work fee. The guide's model engagement letter carries a monthly work fee of $5,000 to $10,000 in addition to the success fee, a success fee with a specified minimum and a declining Lehman-style rate payable at closing, and client reimbursement of travel and the virtual data room; travel was passed on by 74% of firms and the data room by 64%.

The arithmetic in sterling. The Lehman formula is a definition, so I can apply it in pounds: on a £5 million sale, 5%, 4%, 3%, 2% and 1% on five successive millions is £150,000, or 3.0%; on £20 million it is £300,000, or 1.5%. The survey's 4.3% average at $5 million sits above what classic Lehman produces, which tells you minimum fees and ratchets do the work at the small end; I call the gap the Minimum-Fee Wedge, and it is the term to negotiate first.

Is the retainer credited against the success fee?

Usually, and it is the first term to check after the minimum: a £7,500 monthly work fee over nine months is £67,500, an advance on the success fee if credited and an extra 0.3% on a £20 million sale if not. Then negotiate the tail (12 months is common, 24 is long), the exclusivity length with a termination right, the break-up fee if you reject an offer, and whether the fee is calculated on enterprise value with debt assumed and deferred consideration at face, which is how a 2% headline quietly becomes 2.5%.

Which data room should a UK seller use?

You need one from the first buyer conversation; when the buyer most likely to pay is a foreign strategic or a sponsor that already owns your competitor, the data room is the confidentiality system and the W&I file at once. The requirements: staged disclosure so customer pricing, change-of-control clauses and the employee roster sit behind a post-heads-of-terms gate; a room per bidder; dynamic watermarks on every page; NDA gates on sensitive folders; auto-indexing so the disclosure exercise is complete before the insurer's exclusions are drafted; and page-level analytics to see which bidder read the customer-concentration schedule.

The honest landscape:

Bottom line: For a UK software, services, manufacturing or care business under roughly £100 million, Peony's Data Room plan at $52 per admin per month billed annually gives you per-viewer dynamic watermarks, signed NDA gates, a custom domain, unlimited bidder rooms and page-level analytics at a flat rate; Datasite and Intralinks are the right call above £200 million or where counsel requires them.

We make Peony, so this is honest disclosure, including on hosting, which a UK solicitor will ask about first: our UK data room providers guide states the position (US processing under Standard Contractual Clauses on standard plans, UK or EU residency on Enterprise, Drooms and Imprima where counsel mandates European self-serve hosting) and I will not restate it differently. Two UK-specific setups: build the room before the insurer is approached, because the disclosure letter and the W&I exclusions are drafted from its index; and keep the NSIA 17-area assessment and the buyer's ownership chain in a counsel-only folder. Peony holds a 4.8 on G2 and a 4.9 on Capterra, has a registered office in London, and 6,800+ customers run rooms on it today.

Frequently asked questions about UK M&A advisers

Who are the best M&A advisers in the UK?

On dated 2025-26 adviser-of-record evidence, the UK mid-market independents that lead a £5m-£250m sale are DC Advisory (nine UK-linked mandates in its own releases, November 2025 to August 2026) and Alantra (nine, February 2025 to July 2026). In the accountancy-led tier, BDO UK and RSM UK publish dated sell-side releases and Grant Thornton appears in dated trade press. Cavendish has four site-verified UK offices (London, Edinburgh, Manchester, Birmingham) but thin dated evidence; Clearwater's UK business has been subject to a pending KeyCorp acquisition agreement since April 2026. Rothschild & Co and Houlihan Lokey are reference desks for larger deals; K3 Advisory Group, Marktlink and Benchmark International are volume houses. On the Financial Services Register (checked 19 September 2026) DC Advisory, Alantra, Cavendish, Clearwater, Houlihan Lokey, Rothschild & Co, BDO, Grant Thornton, the Big Four LLPs and K3's deal-advisory entity are FCA-authorised; RSM UK Corporate Finance LLP is an ICAEW exempt professional firm, not FCA-authorised; Marktlink, Benchmark International, KBS Corporate and Knight Corporate Finance are not on the register at all, so ask which exclusion or exemption they rely on. I run Peony, the data room 6,800+ teams use, and dated releases are the evidence to demand, not list order.

How much do UK M&A advisers charge?

UK advisers do not publish rate cards, so the only dated evidence is the Firmex Europe M&A Fee Guide 2024-25 (May 2025; 289 European advisers, the UK among the three largest groups), and its figures are in US dollars. Average success fees ran from 4.3% on a $5 million deal, through 3.0% at $20 million and 1.7% at $100 million, to 1.6% at $150 million, and were lower in 2024 than in 2023 at nearly every deal size. The Lehman formula was used by 40% of firms, an accelerating ratchet by 22% and a flat percentage by 26%; monthly work fees were the most common retainer (31%) and the guide's model engagement letter carries $5,000 to $10,000 a month on top of the success fee. More than three-quarters write in a minimum success fee. Treat it as a European range, not a UK table, and negotiate the minimum, the retainer credit, the tail and the exclusivity term.

Does my M&A adviser need to be FCA-authorised?

If the adviser arranges or advises on the sale of your company's shares, yes, or it needs an equivalent lawful footing, because arranging deals in investments is a specified activity under article 25 of the Financial Services and Markets Act 2000 (Regulated Activities) Order 2001 and shares are a specified investment. Three statuses are lawful: directly authorised; an appointed representative of an authorised principal, which the FCA holds responsible for the AR; or unauthorised and relying on staying outside the perimeter, for example by arranging asset sales rather than share sales. Do not take a footer on trust: search the entity on the Financial Services Register at register.fca.org.uk and confirm the status and permissions. Every firm on this page was checked on the register on 19 September 2026: DC Advisory (Daiwa Corporate Advisory Limited, FRN 175853), Alantra Corporate Finance LLP (FRN 478406), Cavendish Capital Markets Limited (FRN 467766), Clearwater Corporate Finance LLP (FRN 483062), Houlihan Lokey UK Limited (FRN 792919), N M Rothschild & Sons Limited (FRN 124451), BDO LLP (FRN 229378), Grant Thornton UK LLP (FRN 231791), Deloitte LLP (FRN 213218), KPMG LLP (FRN 210513), PricewaterhouseCoopers LLP (FRN 221411), Ernst & Young LLP (FRN 196203) and K3 Deal Advisory Capital Markets Limited (FRN 1009438) are authorised; RSM UK Corporate Finance LLP is an ICAEW exempt professional firm, not FCA-authorised; Marktlink, Benchmark International, KBS Corporate and Knight Corporate Finance are not on the register as an authorised firm, appointed representative or exempt professional firm.

How does Business Asset Disposal Relief change in April 2026?

It already has. HMRC's guidance states that BADR taxes qualifying gains at 18% for disposals from 6 April 2026, 14% between 6 April 2025 and 5 April 2026, and 10% on or before 5 April 2025, on a lifetime limit of £1 million set by section 169N(4) of the Taxation of Chargeable Gains Act 1992; non-qualifying gains are taxed at 24% for a higher-rate taxpayer. So the relief is worth 6 percentage points on the first £1 million, a maximum saving of £60,000, down from £100,000 under the 14% rate and £140,000 under the 10% rate. To qualify, for at least two years you must hold at least 5% of the shares and voting rights with 5% economic entitlement, be an employee or office holder, and the company must be trading. Nothing further is scheduled; do not time a sale on the rate.

Should I sell to an Employee Ownership Trust instead?

Only if you can accept market value paid largely out of future profits and a four-year window in which the relief can be clawed back. A qualifying disposal of a controlling interest to an EOT is treated as made for no gain and no loss, the 0% capital gains tax headline, but Finance Act 2025 Schedule 6 set statutory conditions for disposals on or after 30 October 2024: UK-resident trustees; excluded participators may be fewer than half the trustees and must not control the trust; consideration at no more than market value, with deferred-consideration interest at no more than a commercial rate; a disqualifying event in the first four tax years after the year of disposal unwinds the relief; and the claim must state the employee count and the consideration. A trade sale pays cash at completion with BADR at 18% on the first £1 million then 24%. Decide first, because the two routes need different advisers.

Does the National Security and Investment Act apply to my sale?

Only if your company is a qualifying entity in one of 17 defined sensitive areas and the buyer's stake crosses 25%, 50% or 75%, in which case the acquisition is notifiable and must be approved before completion; completing without approval makes it void. The 17 areas in the Cabinet Office guidance (last updated 15 July 2026) run from Advanced Materials, Artificial Intelligence, Communications and Data Infrastructure through Defence, Energy and Military and Dual-Use to Suppliers to the Emergency Services, Synthetic Biology and Transport; the full list is in this guide's NSIA section. Outside them notification is voluntary and material influence is never mandatory, but the government keeps a call-in power. Review takes up to 30 working days, then a 30-working-day assessment extendable by 45; penalties reach 5% of global turnover or £10 million, whichever is greater. With foreign buyers accounting for £25.4 billion of completed UK M&A value in Q2 2026 against £4.2 billion domestic, run the 17-area check before the teaser goes out.

Should I hire a London adviser or a regional corporate finance firm?

Decide on the buyer universe and the deal size, not the postcode. Below roughly £20 million of enterprise value with a UK strategic or regional sponsor buyer pool, a regional corporate finance team that staffs the mandate with a partner usually wins on attention, and Manchester now has its own guide. Between £20 million and £100 million, run a London independent (DC Advisory or Alantra on the evidence) against one accountancy-led team and one regional house, and pick on dated sector deals. Above £100 million, or with foreign strategics and international sponsors as likely buyers, the London desks matter because the buyer list, the NSIA filing and the W&I workstream are global.

Does the Takeover Code apply to my private company?

Almost certainly not. The Takeover Panel's scope page states that since 3 February 2025 the Code applies to a UK registered company only if its securities are admitted to trading on a UK regulated market, a UK multilateral trading facility or a Channel Islands or Isle of Man exchange, or were UK quoted on or after 3 February 2025 and ceased to be within the previous two years. Companies in scope on 2 February 2025 remain transition companies until no later than 2 February 2027, so a formerly quoted private company should check its position with counsel this year. Shares traded only on a private platform such as PISCES do not bring a company into scope, and a company that was never quoted was never in scope.

Is a share sale or an asset sale better for a UK seller?

For an individual seller a share sale is usually better, for statutory reasons. The gain is yours and can qualify for Business Asset Disposal Relief at 18% on the first £1 million of lifetime gains, then 24%; a corporate seller of a trading subsidiary can instead use the Substantial Shareholding Exemption. The buyer pays the transfer tax, currently 0.5% stamp duty on a stock transfer form (HMRC plans a Securities Transfer Tax from 2027, with no rate yet stated), and TUPE is not triggered because the employer does not change. On an asset sale the company pays corporation tax, you then extract the proceeds, and the 2006 TUPE Regulations transfer employees on their existing terms. Buyers ask for asset deals to leave liabilities behind; a clean company with a competent adviser rarely needs to concede one.

Which data room should a UK seller use, and where is the data hosted?

Use a room that gives each bidder its own workspace, gates every folder behind an NDA, stamps each page with the viewer's identity and shows which bidder read the customer-concentration schedule. Peony, which I co-founded, does that at $52 per admin per month on the Data Room plan billed annually (dynamic watermarks, signed NDA gates, custom domain); Deal Team at $64 adds redaction and archive download, Business at $30 carries view-only mode, screenshot protection, link revocation and a simple NDA, and the permanent Free plan carries password-protected links, link expiry and analytics. 6,800+ customers run rooms on it, it holds a 4.8 on G2 and a 4.9 on Capterra, and Peony has a registered office in London. On hosting, our UK data room guide states the position: standard plans process data in the United States under Standard Contractual Clauses with a DPA, and UK or EU data residency, BYOK and self-hosting are available on the Enterprise plan; where counsel mandates European self-serve hosting, it names Drooms and Imprima. Above £200 million, Datasite or Intralinks remain the right call.

How do I verify a UK M&A adviser before I sign an engagement letter?

Four checks, one afternoon. First, the register: search the legal entity name on the Financial Services Register and confirm status (authorised, appointed representative, ICAEW exempt professional firm or absent) and permissions; a marketing name is not an entity name, and this guide prints the 19 September 2026 outcome for every firm it names. Second, Companies House: confirm the entity exists, who controls it and whether ownership has changed, as it did this year at Clearwater UK, HURST and Beever and Struthers. Third, dated deals: three transactions from the last 24 months with the counterparty named, the announcement date and the partner who ran each. Fourth, staffing and terms: who runs the process day to day, and the success-fee schedule, minimum, retainer credit, tail and exclusivity in the engagement letter. If any of the four cannot be answered in writing, keep interviewing.

Is 2026 a good year to sell a UK business?

It is a year in which the buyer who pays is likely to be foreign and the domestic bidders are fewer than a year ago, and neither fact should decide your timing alone. The ONS's provisional Q2 2026 figures (released 1 September 2026) count 353 completed deals of £1 million or more, down from 407 in Q1; inward M&A was worth £25.4 billion across 162 deals, domestic M&A £4.2 billion across 130 deals, down from 241 domestic deals in Q2 2025, a 46% fall. The tax argument for waiting has gone: BADR stepped to 18% on 6 April 2026 and nothing further is scheduled. Sell when the business, the numbers and the data room are ready, and run a process that reaches the foreign strategics and sponsors writing the cheques.
