All figures from each company's latest filed Companies House accounts; detailed filers only, with implausible outliers and scale artifacts excluded. Filed accounts lag the present by roughly 12–24 months, and group-vs-parent scope changes can move a figure between filings. Banks and insurers that don't report a turnover line are under-represented on the turnover-based boards.
