Directors' remuneration as disclosed in filed accounts. Group filings may report key-management-personnel compensation, which is broader than the board; LLP members' profit share is excluded. Treat as "highest disclosed", not a like-for-like board ranking.

Companies ranked from their latest filed accounts at registered offices in Dartford. Registered office is where a company files, which is not always where it trades — see the badges. Implausible outliers are excluded. Snapshot from Companies House.
