Growth between the latest published financial year and the one three years earlier, in full-time equivalents reported in the company's own annual accounts (statutory, not consolidated). Compared companies reported staff for four financial years in a row, were incorporated before the starting year, had at least 10 FTE at the start and accounts less than 3 years old. Growth can also come from a merger, a transfer of business or a financial year of unusual length: each company page links to the filed accounts.

Ranking based on each company's own annual accounts (statutory, not consolidated): a subsidiary and its parent appear separately, and the ranking differs from lists based on consolidated group accounts.
