The UK company law requires every limited company to disclose the PERSON with SIGNIFICANT CONTROL (PSC) of the company with Companies House.
The PSC is anyone in the company who meets one or more of the conditions listed in the legislation. This is someone who:
1) Owns more than 25% of the company's shares
2) Holds more than 25% of the company's voting rights
3) Holds the right to appoint or remove the majority of directors
4) Has the right to, or actually exercises significant influence or control
5) Holds the right to exercise or actually exercises significant control over a trust or company that meets one of the first four conditions
The PSC's names would be published in Companies House website. Where a nominee shareholder or a nominee director is used for your limited company for whatever reasons the PSC in the case would be the person the nominee is representing in the limited company.
