How this is built — and its limits
- Control, not ownership. PSC filings disclose significant control (≥25% shares/votes, board rights, significant influence) — not economic ownership. We never assert a cap table.
- "PSC control" is a band, not an exact stake. Companies House discloses control only in ranges (25–50%, 50–75%, 75–100%), and we show the stronger of the share or voting band on the holding's nearest disclosed edge — the firm's own stake for directly-held companies, the immediate intermediate's for those held through a chain. A band below 50% (or a blank —) here means control rests on board-appointment rights or significant influence rather than a majority shareholding — common in PE structures.
- Every holding is chain-verified. The line under each company ("controlled via N hops · every link ≥X%") is the shortest PSC control chain we found from 3i Group's vehicles down to it — each hop a real Companies House disclosure. Where a company is also controlled by another tracked firm, that's flagged inline.
- Full accounts, not apportioned. A controlled company's figures are counted in full, not scaled by stake. A jointly-controlled asset counts fully under each controller.
- No double-counting. Where a consolidated parent and its subsidiaries both file, only the topmost is counted.
- Coverage is a floor. Only 16 of 80 majority-controlled companies file detailed accounts in our enriched set, so totals understate the true portfolio.
- UK-visible only. Chains that exit to Jersey, Guernsey or other registries terminate there — we can't follow beyond the UK.
