Api Endpoint

Sirenic

UK persons with significant control (PSC register) live from Companies House, for KYB and group-structure checks: LEGAL-ENTITY controllers only (corporate entities, legal persons) with natures of control (ownership/voting bands), notification dates and register identification, plus official PSC statements. Natural-person controllers are COUNTED, never named (GDPR, CJEU C-798/24, since 2026-09-19). Ceased PSCs excluded by default (inclure_cesses=true adds them).
