These are the go-to choice if you're a large business needing audit, international tax structuring, or big-ticket advisory work.\n\n- **Deloitte** – Founded in 1845, Deloitte is part of the global \"Big Four,\" with more than 27,000 professionals in the UK serving finance, healthcare, public sector, private equity and energy clients.\n- **EY** – A prominent player in the UK's professional services sector, with thousands of employees across 21 offices in the UK, known for its focus on financial services, energy, technology, and consumer products.\n- **PwC and KPMG** round out the Big Four, alongside strong revenue positions — the ten largest accounting firms in the UK by revenue are PwC (£5.79bn), Deloitte (£5.6bn), EY (£3.76bn), KPMG (£2.96bn), BDO (£935m), Grant Thornton (£654m), Evelyn Partners (£600.8m), RSM, Azets, and Mazars.\n\n### Strong Mid-Tier Alternatives (SMEs, private clients)\nIf you don't need Big Four scale, these are widely respected and commonly used by UK businesses and individuals:\n\n- **BDO, Grant Thornton, RSM, Azets, Mazars** – all sit just below the Big Four in size and reputation and are commonly chosen by mid-sized businesses.\n- **Moore Kingston Smith** – one of the largest independent firms based in and around London, with a history dating back to 1923, particularly well regarded for corporate finance and forensic accounting work.\n- **Saffery** – best for private clients and complex wealth structures, founded in 1855 with deep expertise advising private clients, trusts and family businesses.\n- **Haines Watts** – has spent decades focusing specifically on owner-managed businesses, with an advisory style that tends to be pragmatic and closely tied to day-to-day business realities.\n- **Xeinadin** – has expanded quickly across the UK and Ireland, built around a network of accountancy practices operating under one group.\n\n### For Freelancers/Small Businesses (outsourced/online accountants)\nSmaller firms like **Makesworth Accountants** are popular for straightforward compliance work — a professional firm offering comprehensive accounting services including bookkeeping, tax preparation, and financial reporting, praised for efficiency, professionalism, flexible pricing and reliable handling of accounts.\n\n---\n\n## Accounting Software UK Businesses Actually Use\nRather than just picking a firm, most UK businesses now pair an accountant with cloud software (especially with Making Tax Digital requirements). Leading firms combine professional expertise with cloud accounting platforms such as Xero, QuickBooks, NetSuite, and Sage. These four are the dominant brands you'll see recommended by UK accountants:\n\n- **Xero** – the most popular cloud platform among small-to-medium UK practices and startups.\n- **QuickBooks** – widely used by sole traders and SMEs, strong Making Tax Digital support.\n- **Sage** – a long-standing UK-based brand, popular with SMEs and payroll-heavy businesses.\n- **NetSuite** – used more by larger, scaling businesses needing full ERP functionality.\n\n---\n\n## Practical Recommendation\n- **Large corporate/complex international needs:** Deloitte, PwC, EY, or KPMG.\n- **Growing SME/private client with more personal service:** BDO, Grant Thornton, Moore Kingston Smith, Saffery, or Haines Watts.\n- **Freelancer/small business/startup:** A smaller online","extractedBrands":[{"name":"Deloitte","domain":"deloitte.com","position":1},{"name":"EY","domain":"ey.com","position":2},{"name":"PwC","domain":"pwc.com","position":3},{"name":"KPMG","domain":"kpmg.com","position":4},{"name":"BDO","domain":"bdo.com","position":5},{"name":"Grant Thornton","domain":"grantthornton.com","position":6},{"name":"RSM","domain":"rsmuk.com","position":7},{"name":"Azets","domain":"azets.com","position":8},{"name":"Mazars","domain":"mazars.com","position":9},{"name":"Moore Kingston Smith","domain":"mooreks.co.uk","position":10},{"name":"Saffery","domain":"saffery.com","position":11},{"name":"Haines Watts","domain":"hwca.com","position":12},{"name":"Xeinadin","domain":"xeinadin.com","position":13},{"name":"Makesworth Accountants","domain":"makesworthaccountants.com","position":14},{"name":"Xero","domain":"xero.com","position":15},{"name":"QuickBooks","domain":"quickbooks.intuit.com","position":16},{"name":"Sage","domain":"sage.com","position":17},{"name":"NetSuite","domain":"netsuite.com","position":18}]},{"provider":"deepseek","run":1,"model":"deepseek-v4-flash","capturedAt":"2026-08-05T04:02:41.585Z","text":"It depends on what you actually need—a big corporate audit, a local accountant for your limited company, or just software to file your Self Assessment. Here’s a practical UK-focused breakdown of the most used and highly regarded options.\n\n## For large businesses, complex tax and audit: The Big Four + mid-tier firms\n\nIf you’re an international company, a large Ltd, or need heavyweight tax advice, the best-known firms are:\n\n- **PwC**\n- **Deloitte**\n- **EY**\n- **KPMG**\n\nThese dominate large corporate audit and complex tax/advisory work. For mid-market and larger SMEs, the most respected UK firms are usually:\n\n- **BDO**\n- **Grant Thornton**\n- **RSM UK**\n- **Mazars**\n- **Moore Kingston Smith**\n- **Saffery Champness** (great for HNW individuals and family offices)\n\nThese are “best” in the sense of prestige and capability, but they’re not what most small business owners actually use day-to-day.\n\n---\n\n## For small businesses, freelancers and contractors: Online accountants people actually use\n\nIf you’re running a small UK business, a limited company, or you’re self-employed, you’re better off looking at cloud-based accountants that bundle software with a dedicated accountant. The most popular in the UK are:\n\n- **Crunch Accounting** – One of the most-used online accountants in the UK. Great for freelancers, contractors, and small limited companies. Includes FreeAgent software, a dedicated accountant, and handles your Self Assessment and Corporation Tax.\n- **Accountancy Cloud** – Another popular choice, especially with startups and founder-led businesses. They charge a monthly fee and include Xero + Dext, with a proper accountant behind it.\n- **Gorilla Accounting** – Very well regarded by contractors, especially those inside/outside IR35. They have strong IR35 expertise.\n- **Coconut** – More of a simple accounting service for sole traders and the self-employed, with a clean app for bookkeeping and tax.\n\nIf you just need someone to file your annual Self Assessment, a local high-street **AAT/ACCA/ICAEW** accountant is often cheaper and fine. But for ongoing support, the online firms above are the ones with the best UK user reviews.\n\n---\n\n## Accounting software “products” people actually use in the UK\n\nIf you want to do it yourself, or your accountant tells you to use a specific product, the standard UK options are:\n\n- **Xero** – The most popular cloud accounting software among UK small businesses. Great for connecting to your bank, invoicing, VAT, and has a huge app marketplace. Strong for selling through apps like Shopify.\n- **QuickBooks** – Very widely used, especially for service-based businesses and payroll. Good all-rounder, and popular with UK bookkeepers.\n- **Sage** – Deeply embedded in the UK. **Sage Accounting** (cloud) is beginner-friendly; **Sage 50** is still the classic for many traditional UK businesses and accountants. Good for VAT and payroll.\n- **FreeAgent** – Built specifically for freelancers and contractors in the UK. Very easy for limited companies and sole traders. Bonus: it’s free if you bank with **Mettle**, or included in certain **NatWest** / **Royal Bank of Scotland** business accounts.\n- **FreshBooks** – Less common in the UK than Xero/QuickBooks, but excellent if you run a service business and want simple invoicing and time tracking.\n- **GoSimpleTax** – Popular for people who only need to file a UK Self Assessment tax return. It works with HMRC and is easy to use.\n- **HMRC’s own online filing** – Free and fine for very simple personal tax returns, but no guidance. Most people prefer a tool.\n\n---\n\n## If you need an accountant, how to choose one in the UK\n\n- Check they are registered with a recognised body: **ICAEW**, **ACCA**, **ICAS**, **IPA** or **AAT**.\n- For VAT, ensure they support **Making Tax Digital (MTD)** for VAT — almost all cloud software and online accountants do now.\n- Read Google/Trustpilot reviews that mention real UK businesses like yours, e.g. “limited company contractor” or “self-employed hairdresser.”\n\n**The short version:**\n- Big corporate? → PwC, Deloitte, EY, KPMG\n- Mid-market UK business? → BDO, Grant Thornton, RSM,","extractedBrands":[{"name":"PwC","domain":"pwc.com","position":1},{"name":"Deloitte","domain":"deloitte.com","position":2},{"name":"EY","domain":"ey.com","position":3},{"name":"KPMG","domain":"kpmg.com","position":4},{"name":"BDO","domain":"bdo.global","position":5},{"name":"Grant Thornton","domain":"grantthornton.com","position":6},{"name":"RSM UK","domain":"rsmuk.com","position":7},{"name":"Mazars","domain":"mazars.com","position":8},{"name":"Moore Kingston Smith","domain":"mooreks.co.uk","position":9},{"name":"Saffery Champness","domain":"saffery.com","position":10},{"name":"Crunch Accounting","domain":"crunch.co.uk","position":11},{"name":"FreeAgent","domain":"freeagent.com","position":12},{"name":"Accountancy Cloud","domain":"accountancycloud.com","position":13},{"name":"Xero","domain":"xero.com","position":14},{"name":"Dext","domain":"dext.com","position":15},{"name":"Gorilla Accounting","domain":"gorillaaccounting.com","position":16},{"name":"Coconut","domain":"coconut.com","position":17},{"name":"QuickBooks","domain":"quickbooks.intuit.com","position":18},{"name":"Sage","domain":"sage.com","position":19},{"name":"FreshBooks","domain":"freshbooks.com","position":20},{"name":"GoSimpleTax","domain":"gosimpletax.com","position":21},{"name":"HMRC","domain":"hmrc.gov.uk","position":22},{"name":"NatWest","domain":"natwest.com","position":23},{"name":"Royal Bank of Scotland","domain":"rbs.co.uk","position":24},{"name":"ICAEW","domain":"icaew.com","position":25},{"name":"ACCA","domain":"accaglobal.com","position":26},{"name":"ICAS","domain":"icas.com","position":27},{"name":"IPA","domain":"ipa.uk.com","position":28},{"name":"AAT","domain":"aat.org.uk","position":29}]},{"provider":"gemini","run":1,"model":"gemini-3.5-flash","capturedAt":"2026-08-05T04:02:41.585Z","text":"Here in the UK, the \"best\" accounting firm is entirely dependent on who you are and what your business needs. The UK has one of the most sophisticated financial services sectors in the world, ranging from multinational giants to highly efficient digital-first practices. \n\nTo help you find the right fit, the top accounting brands and products are categorised below by how they are actually used in the UK market.\n\n---\n\n### 1. The \"Big Four\" (For Multinationals & FTSE 350 Corporates)\nIf you are running a large corporate entity, a listed company, or need complex international tax structuring, the **Big Four** dominate the market. They audit roughly 98% of the FTSE 350.\n*   **PwC (PricewaterhouseCoopers):** The largest accounting firm in the UK by revenue. PwC is the gold standard for high-end corporate audit, global tax planning, and complex forensic accounting.\n*   **Deloitte:** Massively influential, particularly because of its heavyweight consulting and technology advisory arms alongside traditional audit and tax.\n*   **EY (Ernst & Young):** Highly respected for corporate finance, transaction advisory, and assurance. \n*   **KPMG:** Renowned for corporate restructuring, tax advisory, and its solid mid-market corporate expansion services.\n\n* **The Reality:** For the average UK business owner or SME, the Big Four are usually too expensive and their processes too heavy. \n\n---\n\n### 2. The Mid-Market Giants (For Ambitious SMEs, Scale-Ups & Family Businesses)\nThis tier is where the vast majority of established UK businesses actually find their partners. These firms offer the sophistication of the Big Four but with a much more hands-on, relationship-driven approach.\n*   **BDO LLP:** The undisputed leader of the mid-market and the primary \"challenger\" to the Big Four. If you are a fast-growing scale-up or mid-sized business looking to go international, BDO is arguably the most capable partner in the UK.\n*   **Grant Thornton:** Consistently ranks highly for client satisfaction. They are incredibly strong in public sector auditing, advisory, and supporting dynamic, owner-managed UK businesses. \n*   **RSM UK:** Heavily relied upon by regional mid-market businesses. RSM is excellent for practical corporate tax advice, outsourced accounting, and HR/payroll integration.\n*   **Forvis Mazars:** Following their major global merger, they are a formidable force for mid-sized UK enterprises, particularly those with strong European and international trade links.\n*   **Azets UK:** If you run a local business and want a regional presence, Azets has grown rapidly by acquiring local high-street offices. They specialize in local SMEs, offering digital-first bookkeeping and personal tax support.\n\n---\n\n### 3. High-Net-Worth & Specialist Private Client Firms\nIf your needs are personal rather than corporate—such as managing trust funds, inheritance tax planning, landed estates, or complex property portfolios—you want a specialist private client firm.\n*   **Saffery:** Widely regarded as the premier firm for landed estates, agricultural businesses, and ultra-high-net-worth families.\n*   **Blick Rothenberg:** Based in London, they are highly sought after by high-net-worth individuals, tech founders, and international expats moving to or from the UK.\n*   **Crowe UK:** Excellent for non-profits, academies, and private wealth management.\n\n---\n\n### 4. Digital-First & Contractor Specialists (What Small LTDs & Sole Traders Actually Use)\nOver the last few years, the way micro-businesses, contractors, and freelancers handle accounting has shifted. Instead of visiting a physical high-street office, hundreds of thousands of self-employed Brits use **hybrid digital-first firms** that package accounting software together with a dedicated human accountant for a flat monthly fee.\n*   **Gorilla Accounting:** Highly popular among IT contractors, locums, and freelancers. They offer a dedicated accountant and include a premium subscription to FreeAgent software in their monthly fee.\n*   **Crunch:** One of the original and most popular online accounting platforms in the UK. Perfect for sole traders and small limited companies who want an easy, online dashboard to upload receipts and file VAT returns.\n*   **Sleek:** An incredibly popular all-in-one digital service. They manage your bookkeeping, payroll, and HMRC tax filings, using Xero behind the scenes to keep your business running smoothly.\n\n---\n\n### 5. The \"Software\" Products Everyone Uses\nYou cannot discuss modern UK accounting without mentioning the digital tools that power it. Under HMRC’s **Making Tax Digital (MTD)** initiative—which requires digital record-keeping and VAT submissions—nearly every business owner uses one of these three products:\n*   **Xero:** The market leader for UK small-to-medium businesses. Most modern UK chartered accountants are \"Xero Certified\" and will expect you to use this app to feed your business bank accounts directly to them.\n*   **FreeAgent:** Highly popular for freelancers and contractors. *Tip:* If you business-bank with NatWest, Royal Bank of Scotland, or Mettle, you get FreeAgent entirely for free.\n*   **QuickBooks Online:** A powerhouse for small businesses, known for having a highly intuitive mobile app for snapping photos of receipts on the go.\n\n### Summary Recommendation\n*   If you are a **freelancer, sole trader, or contractor**: Go with a digital hybrid like **Gorilla Accounting** or **Crunch**, powered by **FreeAgent** or **Xero**.\n*   If you are a **growing SME or tech startup**: Look at a tech-forward mid-market firm like **Azets** or a specialist regional charter.\n*   If you are an **established mid-market company looking to scale**: Look at **BDO** or **Grant Thornton**.","extractedBrands":[{"name":"PwC","domain":"pwc.com","position":1},{"name":"Deloitte","domain":"deloitte.com","position":2},{"name":"EY","domain":"ey.com","position":3},{"name":"KPMG","domain":"kpmg.com","position":4},{"name":"BDO LLP","domain":"bdo.global","position":5},{"name":"Grant Thornton","domain":"grantthornton.co.uk","position":6},{"name":"RSM UK","domain":"rsmuk.com","position":7},{"name":"Forvis Mazars","domain":"mazars.com","position":8},{"name":"Azets UK","domain":"azets.co.uk","position":9},{"name":"Saffery","domain":"saffery.com","position":10},{"name":"Blick Rothenberg","domain":"blickrothenberg.com","position":11},{"name":"Crowe UK","domain":"crowe.com","position":12},{"name":"Gorilla Accounting","domain":"gorillaaccounting.com","position":13},{"name":"Crunch","domain":"crunch.co.uk","position":14},{"name":"Sleek","domain":"sleek.com","position":15},{"name":"Xero","domain":"xero.com","position":16},{"name":"FreeAgent","domain":"freeagent.com","position":17},{"name":"QuickBooks Online","domain":"quickbooks.intuit.com","position":18}]},{"provider":"google_aio","run":1,"model":"google_aio","capturedAt":"2026-08-05T04:02:41.585Z","text":"","extractedBrands":[]},{"provider":"grok","run":1,"model":"grok-4.5","capturedAt":"2026-08-05T04:02:41.585Z","text":"**The top accounting firms in the UK are dominated by the Big Four, followed by strong mid-tier national firms. Choice depends heavily on business size, complexity, and needs (e.g., FTSE/large corporate audit and advisory vs SME bookkeeping, tax, and compliance).**[[1]](https://accountancyage.com/2025/12/11/accountancy-age-top-5050-rankings-2025-in-partnership-with-intuit-quickbooks/)\n\n### Big Four (Largest by Fee Income and Market Presence)\nThese firms handle the vast majority of large-company audits (especially FTSE 100/250), complex tax, consulting, deals, and risk work. They are the brands large corporates, multinationals, and ambitious scale-ups actually use for prestige, global reach, and depth of expertise. Recent rankings (Accountancy Age Top 50+50 and Accountancy Daily Top 75 surveys) consistently place them at the top by UK fee income:[[2]](https://www.accountancydaily.co/top-75-firms-survey-2025-watershed-year-accountants)\n\n- **PwC (PricewaterhouseCoopers)** — Frequently ranked No. 1 or very top by UK fee income (reports exceeding £6bn in some recent figures; earlier pure-UK figures around £4.3–4.4bn). Strong across audit, tax, deals, and consulting. Widely used by major UK businesses.[[1]](https://accountancyage.com/2025/12/11/accountancy-age-top-5050-rankings-2025-in-partnership-with-intuit-quickbooks/)\n- **Deloitte** — Often No. 1 or 2 (e.g., ~£4.9bn in one pure-UK survey). Excellent for audit, consulting, technology, and risk. Extremely prominent in the UK market.[[2]](https://www.accountancydaily.co/top-75-firms-survey-2025-watershed-year-accountants)\n- **EY (Ernst & Young)** — Consistently top 3 (~£3.7bn+ range). Strong in assurance, tax, strategy, and transactions.\n- **KPMG** — Completes the Big Four (around £3bn range). Solid across audit, tax, and advisory; known for certain sector strengths.\n\nThese four control the bulk of large-listed company audit work and are the default for complex, high-stakes work. They are less cost-effective (and sometimes less personal) for pure SMEs.[[2]](https://www.accountancydaily.co/top-75-firms-survey-2025-watershed-year-accountants)\n\n### Leading Mid-Tier / Next-Tier Firms\nThese are excellent alternatives for growing businesses, mid-market companies, and many SMEs needing strong national coverage, technical depth, and better value/personal service than the Big Four. They are frequently recommended and actively used:\n\n- **BDO** — Clearly the fifth-largest (first to break £1bn fee income in recent surveys). Strong national footprint, good for mid-market audit, tax, and advisory. A very popular “step up” from smaller firms.[[1]](https://accountancyage.com/2025/12/11/accountancy-age-top-5050-rankings-2025-in-partnership-with-intuit-quickbooks/)\n- **Grant Thornton UK** — High mid-tier ranking (often 6th–7th, ~£650m+). Broad services, private equity backing for growth, solid for SMEs scaling up and mid-market clients.\n- **RSM** — Strong national presence and growth; frequently ranked highly in the top 10. Good all-rounder for businesses needing proactive advice.\n- **Evelyn Partners** (formerly linked to Smith & Williamson) — High mid-tier (around 6th in some tables, ~£650m+). Strong in wealth, tax, and private client/business services; private equity backed.\n- Others frequently appearing high in rankings and used by businesses: **Azets** (consolidator with good SME focus, often top 10), **Forvis Mazars**, **Moore UK**, **Crowe**, **MHA**, **Sumer** (fast-growing via acquisitions, SME champion), **PKF**, and **Saffery**.[[2]](https://www.accountancydaily.co/top-75-firms-survey-2025-watershed-year-accountants)\n\nThese mid-tier firms are what many growing UK businesses “actually use” once they outgrow a local high-street accountant but don’t need (or want to pay for) Big Four scale.\n\n### For Small Businesses, Start-ups, Sole Traders & Freelancers\nBig Four/mid-tier can be overkill and expensive. People commonly use:\n- Local or regional chartered firms (ACA/ACCA qualified) recommended via word-of-mouth, ICAEW/ACCA directories, or platforms like Unbiased.\n- Specialist SME/cloud-focused firms and franchises such as TaxAssist Accountants, Crunch, Mazuma, Accounts and Legal, Gorilla Accounting, and various fixed-fee or virtual providers. These emphasise accessibility, cloud tools, fixed pricing, and practical support (VAT, payroll, Corporation Tax, self-assessment).[[3]](https://myiva.co/blog/10-best-accountants-for-small-businesses/)\n- Many SMEs work with accountants who are Xero- or QuickBooks-certified for seamless cloud bookkeeping.\n\n**Look for** qualified professionals (ICAEW, ACCA, or AAT), good reviews (Trustpilot, Google), fixed-fee options where possible, and proactive advice rather than pure compliance. Sector specialists (e.g., contractors, e-commerce, property) add real value.\n\n### Accounting Software Brands People Actually Use (UK)\nFirms and businesses heavily rely on cloud platforms (Making Tax Digital compliant):\n- **Xero** — Often the default/most recommended for UK SMEs. Excellent bank feeds, integrations (1,000+), and accountant ecosystem. Extremely widely adopted.[[4]](https://bankreconciler.app/blogXeroVsQuickBooksVsSage)\n- **QuickBooks Online (Intuit)** — Strong contender, popular for its features, reporting, and ease; frequently partnered with rankings and firms.\n- **Sage** — Long-established UK brand (Sage 50, Sage Business Cloud). Preferred by many for more complex needs, payroll, or traditional setups; still very common.\n- Others: FreeAgent, KashFlow, or simpler tools for micro-businesses; enterprise systems (e.g., Oracle, SAP, or Microsoft Dynamics) for larger firms via the Big Four/mid-tier.\n\nMost modern UK accountants push cloud software for real-time collaboration, automation, and MTD compliance. Xero has particularly strong mindshare among UK practices and SMEs.\n\n### Quick Recommendations by Need\n- **Large corporate / listed / complex multinational** — Big Four (PwC, Deloitte, EY, or KPMG).\n- **Mid-market / scaling SME needing national reach and expertise** — BDO, Grant Thornton, RSM, or Evelyn Partners/Azets.\n- **Small business / start-up / sole trader** — Reputable local/qualified firm or specialist SME provider using Xero/QuickBooks; prioritise fit, communication, and fixed fees over brand prestige.\n- **Always** — Check latest fee income rankings (Accountancy Age Top 50+50 or Accountancy Daily Top 75), client reviews, cultural fit, and specific expertise (tax, sector, international). Fees, service quality, and partner attention vary significantly even within the same tier. Consider getting quotes from 2–3 firms and asking about technology stack and proactive advisory.\n\nThe market is dynamic with private equity investment, consolidations (e.g., Azets, Sumer, Xeinadin), and growth in mid-tier firms, so mid-sized options are stronger than ever for many UK businesses. For personalised advice, speak to a few firms or use a matching service, and verify current qualifications and insurance.","extractedBrands":[{"name":"PwC","domain":"pwc.com","position":1},{"name":"Deloitte","domain":"deloitte.com","position":2},{"name":"EY","domain":"ey.com","position":3},{"name":"KPMG","domain":"kpmg.com","position":4},{"name":"BDO","domain":"bdo.com","position":5},{"name":"Grant Thornton UK","domain":"grantthornton.co.uk","position":6},{"name":"RSM","domain":"rsmuk.com","position":7},{"name":"Evelyn Partners","domain":"evelyn.com","position":8},{"name":"Azets","domain":"azets.co.uk","position":9},{"name":"Forvis Mazars","domain":"mazars.com","position":10},{"name":"Moore UK","domain":"moore.co.uk","position":11},{"name":"Crowe","domain":"crowe.com","position":12},{"name":"MHA","domain":"mha-uk.com","position":13},{"name":"Sumer","domain":"sumer.com","position":14},{"name":"PKF","domain":"pkf.com","position":15},{"name":"Saffery","domain":"saffery.com","position":16},{"name":"Xero","domain":"xero.com","position":17},{"name":"QuickBooks Online","domain":"intuit.com","position":18},{"name":"Sage","domain":"sage.com","position":19},{"name":"FreeAgent","domain":"freeagent.com","position":20},{"name":"KashFlow","domain":"kashflow.com","position":21},{"name":"Oracle","domain":"oracle.com","position":22},{"name":"SAP","domain":"sap.com","position":23},{"name":"Microsoft Dynamics","domain":"microsoft.com","position":24}]},{"provider":"openai","run":1,"model":"gpt-5.5-2026-04-23","capturedAt":"2026-08-05T04:02:41.585Z","text":"## Short answer: the best UK accounting “brands” to start with\n\nIf you mean **accounting firms to hire**, the safest shortlist is:\n\n1. **PwC** — best for large UK/international businesses, complex audit, tax, deals, consulting.  \n2. **Deloitte** — best for large businesses needing audit plus technology/consulting transformation.  \n3. **EY** — best for tax, audit, transactions, international work.  \n4. **KPMG** — best for regulated industries, audit, tax, risk and advisory.  \n5. **BDO** — best “non-Big Four” option for mid-market companies.  \n6. **Grant Thornton UK** — strong for mid-market audit, tax, advisory and growth businesses.  \n7. **RSM UK** — strong for SMEs, owner-managed businesses and mid-market companies.  \n8. **Azets** — good for SMEs, regional businesses, payroll and outsourced accounting.  \n9. **Forvis Mazars** — good for audit, tax and international mid-market work.  \n10. **Evelyn Partners / S&W** — good for private clients, entrepreneurs, wealth-linked tax and business advice.\n\nBy current UK scale, **PwC, Deloitte, EY and KPMG remain the dominant “Big Four”**, with PwC listed as the UK’s largest accountancy firm by turnover, followed by Deloitte, EY and KPMG; BDO, Grant Thornton and RSM are the next major names commonly used by larger SMEs and mid-market companies.
