The Big 4 accounting firms table ranks the top four firms in the UK by total UK fee income.
PwC, Deloitte, EY and KPMG are the leading players in the accountancy industry, with their services spanning advisory, audit and assurance, tax, risk consulting and management consulting, and capital and transaction management. All four firms work across a variety of industries, including aerospace, automotive, banking, construction, hospitality, pharmaceuticals, transportation, wealth management, media, government and public sector, manufacturing, private equity, technology, oil and energy, financial services, healthcare, insurance, professional services, real estate, retail, and telecommunications.
The Big 4 have experienced significant growth in recent years, and the UK firms are part of a global network of firms across Africa, the Americas, Asia-Pacific, Europe, and the Middle East.
Collectively, PwC, Deloitte, EY and KPMG have over 3,000 partners. The current senior partners and leaders of each UK firm are Kevin Ellis (PwC), David Sproul (Deloitte), Steve Varley (EY), and Bill Michael (KPMG).
As part of firm strategy and direction, all four firms have strengthened their focus on tackling key economic and social issues affecting both the accountancy sector and the UK as a whole in recent years. These issues include Brexit, diversity and the gender pay gap, social mobility, and digital transformation.
