Statistics - Audit firms
Sources for statistics on audit firms, including fee income and stock market clients.
Fee income of registered firms
The Financial Reporting Council (FRC) has published an annual survey of the profession called Key Facts and Trends in the Accountancy Profession since 2002 which includes a section on audit firms in the UK and the Republic of Ireland.
The report includes information on the fee income of many of the larger registered audit firms as well as charts which show the split between audit fee income, fee income from non-audit work to audit clients and fee income from non-audit clients. A separate table is provided which shows the fee income of audit firms registered with the ICAEW by size.
An archive of previous editions are available through the FRC website.
