Get the PSC (Persons with Significant Control) register for a UK company. Returns individuals, corporate entities, and legal persons who own 25%+ of shares, hold 25%+ of voting rights, or have significant influence or control. Each PSC includes decoded control types in plain English (e.g. 'Owns 25-50% of shares' instead of raw codes). Individual PSCs also carry ECCTA identity verification: verification_status (verified, pending, overdue or unknown), identity_verified, identity_verified_on, and verification_deadline. pending means that person's deadline has not yet passed and is not a compliance failure; unknown means Companies House publishes no record for them, an absence of data rather than a breach. Only overdue means a deadline was missed. Corporate entity PSCs include their company number for ownership chain traversal, and carry none of the verification fields. Also detects PSC exemptions for listed PLCs. Cached for 24 hours.
