How this list was made

Industry
Companies with any of these SIC codes on their Companies House record:
  • 69201 – Accounting and auditing activities
  • 69202 – Bookkeeping activities
  • 69203 – Tax consultancy
Location
The whole UK: every company on the register, wherever its registered office is.
Periods compared
Each company's latest annual accounts against its accounts for the year before. Companies whose two latest accounts are not for consecutive years are left out.
Ranking
Ranked by the percentage change in net assets between the latest two consecutive annual accounts. Companies must have started with net assets of at least £50,000, so very small starting values cannot top the list.
Exclusions
Companies that are dissolved, in liquidation, in administration or proposed to be struck off; dormant companies; and companies whose latest accounts end more than 21 months before the newest accounts in the data (or are dated after it). Figures that cannot be right, which are most likely filing errors, are also left out:
  • net assets more than 50 times the year before
  • net assets above £100,000,000 in micro-entity accounts, or above £1,000,000,000 in small company accounts
