Ownership and control

Companies House does not publish a PSC register for LSEG because the company has voting shares admitted to trading on a UK regulated market. For a listed company, ownership is therefore better understood through the share register, major-shareholder disclosures and market filings than by expecting a conventional PSC entry.

A public-company profile is not a real-time shareholder register. Briefed separates the legal entity record from market ownership so a stale or incomplete registry field is not presented as the whole ownership picture.
