About the UK accounting companies sector
The UK accounting sector is one of the largest professional-services markets in Europe. The Big Four (PwC, Deloitte, EY, KPMG) lead by revenue, but thousands of mid-market and independent UK accounting firms operate across England, Scotland, Wales and Northern Ireland. Together they make up the full list of accounting companies in the UK shown on this page.
If you are looking for a list of accounting companies in the UK for outbound sales, an email list of UK accountants for marketing campaigns, or a mailing list for direct outreach, the list above is filterable by region, employee size, revenue band and founding year. Every active firm is verified against the UK companies register. Export to CSV or Excel, or request a free sample to evaluate.

UK accounting companies fall under the Business Services SIC division. The primary UK SIC 2007 code is 69201: Accounting and auditing activities. The list above covers every active UK company tagged with this code plus closely related codes, so the regional and revenue breakdowns reflect the entire sector rather than a sample.
