Updated 2 August 2026
You are generally a PSC if you:
- hold more than 25% of the shares
- hold more than 25% of the voting rights
- can appoint or remove a majority of the board
- otherwise exercise significant influence or control
Companies House keeps a register of PSCs so it is clear who is behind a company. Every PSC must verify their identity.
