Top Accounting Firms in the UK

Over the years, I have worked in accounts for a various amount of UK and international businesses, these have ranged from small start-up businesses to internationally recognised manufacturing companies. My roles have also varied, I have been the local bookkeeper to the companies cost accountant. Through my years of accounting experience though, I have never worked for a large accountancy firm or practice. I have worked with chartered accountancy firms but these have been small town-based practices. In this post I will list the top 5 accounting firms in the UK by revenue.

Accounting Firm #1 - PwC

PwC (PricewaterhouseCooper) is the largest professional services firm in the world, not just the UK. In the UK alone, PwC had an annual turnover of £2,814,000,000 in 2015 and is number 1 on our top accounting firm list. It's main financial and accounting services include assurance, advisory and tax related services. PwC was founded in 1998 (merged from Price Waterhouse and Coopers & Lybrand).

Accounting Firm #2 - Deloitte

Deloitte (Deloitte Touche Tohmatsu Limited) was founded in 1845 in London, England, it's headquarters now in New York City, USA. It's main services include audit and consulting services. Deloitte recently had a annual turnover of £2,550,000,000 in the UK and is number 2 on our top accounting firms list.

Accounting Firm #3 - KPMG

KPMG, formerly KMG (Klynveld Main Goerdeler) before merging with Peat Marwick, specialises in audit, advisory and tax related services. Though KPMG is number 3 on our top accounting firm list, it is perhaps the most recognised accounting brand in the UK, this could be due to the media attention in recent years with KPMG being designated many times to oversee the administration of several UK companies. KPMG recently had an annual turnover of £1,874,000,000 in the UK and has it's headquarters in Amstelveen, Netherlands.

Accounting Firm #4 - EY

EY (Ernst & Young) was founded in 1989 through the merger of Ernst & Whinney and Arthur & Young Co. The company had a recorded UK turnover of £1,860,000,000 in 2015 and has seen much expansion in the 21st century. It's main financial and accounting services include advisory, tax and assurance related services.

Accounting Firm #5 - Grant Thornton UK

Grant Thornton was founded in 1980 and has it's headquarters in London, England. The accounting firm continues to grow and is number 5 on our top accounting firm list. In 2015, Grant Thornton recorded a UK annual turnover of £515,000,000.
