Statistics - Accountancy firms by age of business

Sources for statistics on accountancy firms by age of business.

Age of business

United Kingdom: All firms


The ONS publication UK Business: Size, Activity and Location provided statistics on the number of firms in four groups, depending on the age of their business (less than 2 years, 2-3 years, 4-9 years, 10 or more years). This table was not included in the 2014 edition of UK Business: Size, Activity and Location.

Previous editions of UK Business: Size, Activity and Location can be accessed via the National Archives web site.

The figures are published in Table B3.3: United Kingdom - Number of VAT and/or PAYE based enterprises in all industries by age of business. The table shows statistics for a number of sectors and you will need to scroll down to the appropriate UK SIC code for accounting, book-keeping and auditing activities; tax consultancy (7412 in UK SIC 2003 - as used in the 2008 publication, 6920 in UK SIC 2007 - as used from the 2009 publication onwards).

These statistics record both VAT and PAYE based enterprises using the UK SIC code for accounting, book-keeping and auditing activities; tax consultancy. As such, they include all firms with this classification - not just the member firms of the CCAB bodies.

If comparing figures from different releases, please note that various changes have been made to the coverage of businesses over the years. See the publication's methodology for details.


Older editions of this publication are also available but it should be noted that the 2008 publication was 'the first to include businesses based on PAYE employers that are not also registered for VAT, extending the scope from the previous VAT-based tables.' This means that the figures from earlier editions cannot be compared directly with the 2008 edition or any subsequent editions.
