How this list is made

From each company's latest accounts filed at Companies House, or its annual report for listed groups: the figures as filed, nothing estimated. Changes compare the two latest filed years. Only companies that report in pounds are ranked; groups that report in dollars or euros aren't converted. Subsidiaries whose figures are part of a listed group's are counted once, in the group. Updated daily as new accounts are filed.
