Sell Your Accounting Business in the UK (2026): Multiples, PE Buyers, Regulator Transfer & Tax Structuring - CT Acquisitions

Sell Your Accounting Business in the UK

Cpa Accounting business in the UK

If you operate an accounting business in the UK and you have searched “sell my accounting business in the UK”, the variables that drive your sale price are United Kingdom-specific in ways the broader category data does not capture. The named PE platforms with active deal posture in the UK in 2026, the EBITDA-tier multiples bands stated in £ GBP, the jurisdiction-specific tax-arbitrage structuring (which is the single largest after-tax lever any owner has), the regulator transfer procedure under HM Revenue & Customs (HMRC) and the relevant industry licensing body, and the 2024-2026 dated comparable transactions all reshape the multiple a buyer will pay. This page walks through the the UK valuation framework as accounting businesses are actually trading in mid-2026, the named buyers actively acquiring here, and the regulator transfer + tax structuring that determine net-of-tax proceeds.

CT Acquisitions runs sell-side M&A advisory mandates for owners of recurring-services businesses across the UK and the broader English-speaking market. The introductory conversation is confidential and NDA-protected. This page is the localised valuation framework for 🇬🇧 the UK accounting sellers, built from named-and-dated 2024-2026 transactional research rather than generic broker-listing rules of thumb.

The the UK accounting M&A landscape in 2026

The detailed market sizing, named-buyer table, EBITDA-tier multiples bands, regulator transfer procedure, jurisdiction-specific tax-arbitrage structuring, and 2024-2026 dated comparable transactions for the UK accounting are set out below. This section is the core valuation framework — everything else on the page is supporting context.

17. CPA-ACCOUNTING (UK)

1. Market Size & Structure

The UK accountancy services market is one of the largest professional-services markets in Europe. The Office for National Statistics’ Annual Business Survey aggregates SIC 69.20/1 (accounting and auditing activities) and SIC 69.20/2 (bookkeeping activities) at a combined £36.4bn of UK turnover for 2023, the most recent ONS data. Adding SIC 69.20/3 (tax consultancy) takes the total to ~£41bn. The IFA, ICAEW, ACCA and AAT memberships combined cover roughly 480,000 individual practitioners and trainees in the UK as of late 2024 per the FRC’s Key Facts and Trends in the Accountancy Profession 2024 report.

By revenue, the UK accountancy profession is split into 4 tiers:

Tier 1: Big Four — Deloitte UK, PwC UK, KPMG UK, EY UK. Combined UK fee income ~£20bn (FY2024). Not in scope.

Tier 2: Mid-tier (“challenger”) firms — BDO UK, Grant Thornton UK, RSM UK, Forvis Mazars (rebranded from Mazars in June 2024 after the US merger), Crowe UK, PKF, Saffery (rebranded from Saffery Champness), Evelyn Partners (Smith & Williamson + Tilney combined in 2020, now owned by Apax Partners since the September 2024 acquisition of S&W). Fee income £150m to £900m. Partially or fully PE-backed in several cases.

Tier 3: Roll-up platforms (PE-backed mid-market consolidators) — Per the Business & Accountancy Daily Top 75 Firms Survey 2025, 17 firms in the Top 75 are PE-backed with combined fee income up 19.8% YoY to £2.73bn versus an overall Top 75 growth of 5%.

Named platforms:

Tier 4: Independent practices — Roughly 11,500 to 13,000 ICAEW practising firms and ~3,800 ACCA registered firms in the UK. Most are sub-£2m fee income. The 800+ practices with fee income £2m to £15m are the actively-traded pool for the PE consolidators.

2. PE Buyer Landscape

UK accountancy is the most concentrated PE roll-up sector in UK professional services. Per the 2025 Top 75, 17 of the top 75 firms are PE-backed and they are growing roughly 4x as fast as the un-backed firms.

Strata A: UK lower-mid-market PE platforms ($30m to $200m EBITDA platform creation) — This is the layer that buys £1m to £8m EBITDA founder-led practices and rolls them into a national platform:

Strata B: UK mid-market PE generalists:

Strata C: International / US platforms expanding into UK:

3. EBITDA-Tier Multiples Bands

Accounting roll-up multiples in the UK have come off the 2023 peak (which saw take-privates and platform creations at 13x-to-15x EV/EBITDA) into a 9x-to-12x normal band for 2026.

The Xeinadin and Sumer case study (Henrico Dolfing’s analysis of the hidden assumption behind accounting roll-ups) is required reading for any UK accounting owner contemplating a PE sale. The headline-multiple sticker price masks earnouts, deferred consideration, sweet-equity dilution and the integration tax that compresses post-completion economics.

4. Regulator Transfer & Licensing

UK accountancy has the densest regulatory wrapper of any UK professional-services sector.

ICAEW Practice Licence: Any ICAEW-member firm describing itself as ICAEW Chartered Accountants requires an ICAEW Practising Certificate held by at least one principal, and Practice Assurance registration. Change of beneficial ownership (control acquisition above 25%) must be notified to ICAEW Practice Regulation within 30 days.

ACCA Practice Certificate: ACCA-member practitioners require an ACCA Practising Certificate. Where ACCA members are principals, the firm requires ACCA Registered Practice status. Notification of control change to ACCA within 30 days.

Audit Registration (FRC, RSB): Statutory audit work is reserved to firms registered with a Recognised Supervisory Body (ICAEW the largest, ACCA, ICAS Scotland, CAI Ireland/NI). On control change the RSB will assess the new control. Where the firm holds Public Interest Entity (PIE) audits the FRC’s direct regulation applies.

AML Supervision: Under the Money Laundering Regulations 2017 (as amended), every firm providing accounting, tax, trust-or-company-formation or insolvency services must be supervised for AML. Default supervisors are ICAEW, ACCA, ICAS, ATT, CIOT, AAT and IFA for member firms; HMRC supervises the unaffiliated.

FCA Registration (Designated Professional Body regime): ICAEW and ACCA both operate as Designated Professional Bodies under FSMA 2000 Part XX, which allows their member firms to undertake limited incidental investment business without separate FCA authorisation. On a sale, FCA Form A (Change in Control) under FSMA s.178 applies for any acquisition of 10% or more of an FCA-authorised firm; the FCA has 60 working days to determine.

Insolvency Practitioner Licensing: IP licence is personal not firm-level under the Insolvency Act 1986.

HMRC Agent ID, Companies House Authentication, ICO Registration — all transferable but require notification at completion.

5. Tax Structuring & Arbitrage

UK accounting-practice owners selling in 2025-2026 face the same BADR arbitrage as HVAC owners, but with additional structuring nuances driven by the LLP-to-Ltd conversion that most sell-ready firms execute pre-process.

LLP-to-Ltd conversion: Most UK accountancy practices operate as LLPs (Limited Liability Partnerships under the LLPA 2000). LLPs are tax-transparent (partners taxed on their profit share at marginal rates of up to 45% income tax + 2% NIC), which is unattractive to a PE buyer wanting EBITDA-multiple sale economics. Standard pre-sale step is to incorporate the LLP business into a Ltd company at market value, with the LLP partners taking shares in the new Ltd as consideration. The reorganisation needs 12 months minimum to season the SSE and BADR qualifying-period clocks.

Business Asset Disposal Relief rate trajectory:

For a 5-partner firm where each partner holds 20% of the converted Ltd, each partner uses their own £1m BADR cap. Pre-6 April 2026 completion captures the 14% rate on £5m of gross gain (vs 18% post-cliff), a delta of £200k across the 5 partners on the first £5m.

Substantial Shareholding Exemption (SSE): For a converted Ltd with a UK Topco interposed at least 12 months pre-sale, SSE shields the corporate gain on the sale.

Section 135 share-for-share rollover on the partner roll-over equity into the PE buyer’s Newco.

Goodwill amortisation deductibility: Corporation tax relief on the buyer’s amortisation of customer-relationship goodwill is restricted under CTA 2009 Part 8; for related-party transfers between connected persons it is generally non-deductible.

EOT route: Available but rarely chosen in PE-aware accountancy markets given the multiple-arbitrage. EOT sales at headline 5x to 6x partner profit-share vs PE process at 8x to 11x EBITDA.

Personal service company / IR35 risk: Many accounting firms historically engaged partners and senior managers via PSCs. The off-payroll working rules (IR35 reformed for the private sector in April 2021) push most accountancy firms back to employed-status for senior managers.

6. NSI Act 2021 + CMA Merger Review

Accountancy practice acquisitions sit largely outside the 17 mandatory NSI sectors. Two exceptions: Critical Suppliers to Government (firms providing internal-audit or finance-transformation services to HMG departments under significant Crown Commercial Service frameworks), and Critical Suppliers to Emergency Services (rare for non-specialist mid-market firms). The voluntary regime allows a call-in within 5 years (or 6 months of awareness).

CMA merger control: Under the Enterprise Act 2002 (as amended by the DMCC Act 2024 with the £100m UK turnover test from 1 January 2025) the mid-market UK accountancy sector is generally below the jurisdictional thresholds. The DMCC Act 2024 also introduced a new merger threshold (the “merger of an existing or potential competitor” test triggered by 33% UK share + £350m UK turnover of one party). Sumer at £300m and Azets at £405m are within sniff of these thresholds for the largest bolt-ons.

7. Recent Transactions (2024-2026 named)

  1. Goldman Sachs Alternatives acquires AAB Group from August Equity, announced July 2025, estimated £250m per Daily Business. August Equity returns its seventh successful realisation since 2022 at a blended 4.6x money multiple.

  11. Forvis Mazars formal launch June 2024 (combination of Mazars UK with US Forvis network).

8. Regional Sub-Markets

London and South East: Highest fee-per-partner, premium client base, corporate-finance and tax-advisory revenue mix above 35%. Concentration of financial-services, technology, media, real-estate, private-client (HNW and UHNW) work. Buyer competition is most intense here; multiples sit 0.5x to 1.0x above national average. Local platforms: Raffingers (now Xeinadin), Silver Levene (now Xeinadin), HW Fisher, Saffery, BKL.

Midlands: Birmingham, Nottingham, Leicester. SME-heavy compliance base with growing tech and professional-services advisory revenue. Cooper Parry (Lee Equity, ex-Waterland) is the dominant Midlands platform.

North West: Manchester, Liverpool, Lancaster. Strong manufacturing and SME client base with healthcare and tech advisory growth. DJH (Tenzing) is the Stoke/Manchester-led platform.

North East: Newcastle, Durham, Teesside. Lower fee-per-partner, heavy SME compliance base.

Yorkshire: Leeds, Sheffield, Hull. Leeds financial-services district drives premium-office advisory.

Scotland: ICAS-regulated rather than ICAEW. Distinct regulatory regime. Strong AAB / Goldman Sachs presence (Aberdeen, Edinburgh, Glasgow); Johnston Carmichael (independent, Scottish HQ in Aberdeen).

Wales: Smaller market, regulatory regime same as England. Bevan Buckland (independent, Swansea / Cardiff) is the largest indigenous Welsh firm.

Northern Ireland: Distinct regulatory environment (CAI and ACCA dominant; ICAEW present). Cross-border practice into RoI common. AAB has Belfast presence post-James Walter Hamilton acquisition.

9. Labour and Workforce

Trade unions: Largely non-unionised at the practice level. Prospect union represents some HMRC and FCA staff but practice-firm union density is below 5%.

Shortage status: SOC 2024 codes 2421 (chartered and certified accountants) and 2422 (management accountants) both sit on the Migration Advisory Committee’s Shortage Occupation List as of the 2024 SOL refresh. The Skilled Worker visa salary threshold of £38,700 (from April 2024) plus the £41,500 going-rate for SOC 2421 makes visa-sponsorship a routine talent-acquisition tool.

Newly-qualified pipeline: ICAEW ACA qualifications awarded 2024 ~5,800 per ICAEW Key Facts. ACCA new fellows ~10,200 globally with ~3,400 UK. AAT qualifications ~13,000 annually. Big Four hires 55% of ICAEW ACA trainees; mid-market and lower-mid-market firms compete for the remainder.

Wages: Newly-qualified ICAEW ACA in London commands £60k to £65k base 2026 per Robert Half Salary Guide; manager-level £75k to £90k; director / partner-track £100k to £160k; equity partner profit-share £180k to £450k+ in mid-tier and roll-up platforms. Outside London discount 25-35%.

Partner retention post-sale: Standard PE-platform model locks partners in via 3-to-5-year service agreements with non-compete and non-solicit covenants, equity rollover at the platform level (5% to 20% of consideration), and ratchets tied to EBITDA growth. The acid test is the second partner to leave (the first leaver is expected; the second triggers a panic).

10. Working Capital and Asset Considerations

Accountancy working capital is dominated by debtors and work-in-progress (WIP); fixed assets are minimal.

WIP and debtor balances: A mid-market accountancy practice typically runs WIP at 6 to 10 weeks of revenue and debtor days at 65 to 95 days. NWC sits at 18% to 25% of revenue, materially higher than HVAC or any installer trade. Buyers diligence the WIP-aged provision aggressively; partners notoriously over-state recoverable WIP on jobs they personally booked. Standard QofE adjustment is 15% to 25% writedown on WIP older than 90 days and 100% writedown on debtors older than 180 days unless specific evidence of recovery.

Deferred consideration / earn-out: Standard PE-roll-up earn-out is 25% to 40% deferred over 3 years against EBITDA hurdles. Trade buyers (Tier 2 firms) tend toward 20% deferred / shorter term.

Practice goodwill on the balance sheet: Where the firm previously bought another practice and capitalised goodwill under FRS 102, that goodwill carries through but is irrelevant to the multiple. The valuation runs off normalised EBITDA, not balance-sheet net assets.

Professional indemnity insurance: Run-off cover for the selling LLP / Ltd structure typically covers 6 years post-sale and is a routine SPA condition. Six-year run-off premium runs 30% to 60% of the final-year PII premium as a one-off cost, captured in the equity bridge.

Practice management system / IT stack: CCH ProSystem fx (Wolters Kluwer), IRIS Practice Management, Xero Practice Manager, QuickBooks Online Accountant.

Client-money accounts: Where the firm holds client money, the regulatory regime under the Money Laundering Regulations 2017 and the ICAEW Clients’ Money Regulations applies. Audit-clean client-money balances are a closing condition. Reconciliation discrepancies are the most common closing-day delay in UK accountancy sales.

Frequently asked questions: selling the UK accounting businesses in 2026

What multiple should I expect for my the UK accounting business in 2026?

Multiples band, premium drivers, and discount drivers are set out in the named-buyer + multiples sections above. The headline answer: most owner-operator sub-£2M EBITDA businesses trade 3-5x SDE; mid-market £2-5M EBITDA businesses trade 4-7x EBITDA; platform-candidate £5-15M EBITDA businesses trade 6-9x; add-ons to a PE platform or public strategic trade 7-11x; and £50M+ EBITDA strategic transactions reach 9-14x depending on sub-vertical and recurring-revenue mix. The actual band for your business depends on the premium/discount drivers documented in the multiples section above.

Which PE platforms and strategic acquirers are actively acquiring the UK accounting businesses in 2026?

The named-buyers section above lists the 3-5 most-active acquirers in the UK for accounting as of mid-2026, with ownership, HQ, recent acquisitions, and approximate revenue band documented per buyer. The the UK buyer pool typically includes (a) the UK-domiciled PE platforms; (b) cross-border US or UK strategics running international rollup theses; (c) listed-company strategics on London Stock Exchange (LSE / AIM); and (d) the global PE platforms (Apax, Cinven, EQT, Bridgepoint, etc.) running cross-border platforms.

How does the HM Revenue & Customs (HMRC) regulator-transfer procedure affect my sale timeline?

The regulator-transfer procedure section above documents the specific consents, novations, or new-entity applications required for a the UK accounting sale. Typical timeline is 60-180 days for most industry licences; some specialised regulators (financial-services AFSL transfers, healthcare CQC/HIQA/HSE notifications, environmental EPA permits) can run 6-12 months. Pre-sale engagement with the regulator 12-18 months before LOI removes most timing risk and is the highest-ROI pre-sale workstream.

What tax-arbitrage structuring is available to the UK accounting sellers in 2026?

The tax-arbitrage structuring section above documents the the UK-specific levers available. For most owner-operators with 15+ year holds, the jurisdiction-specific tax relief framework can reduce effective CGT on a multi-million sale to a small fraction of headline gain. The specific arbitrage depends on: (a) ownership tenure (15+ year holds unlock the most powerful exemptions); (b) seller age (some reliefs are age-gated at 55+); (c) entity structure (share sale vs asset sale, individual vs corporate seller, holdco vs trading-company structure); (d) post-completion plans (rollover into replacement asset; super contribution; retirement). Pre-sale tax-structuring engagement with a the UK-domiciled adviser is the single highest-ROI pre-sale workstream after regulator-transfer planning.

What recent 2024-2026 dated comparable transactions in the UK accounting should I know about?

The recent-transactions section above lists the 1-3 most-relevant dated comparable transactions in the UK accounting from 2024-2026 with named buyer, named target, approximate consideration where disclosed, and source citations.
