| Shareholders Note |
This is the UK statutory members register (the legal shareholder list under Companies Act 2006 Part 8). It is NOT the Persons with Significant Control (PSC) register - the two disagree: a 10% shareholder appears here but not in PSC; a corporate trustee can appear in PSC without being on this members register. If the user asked about 'shareholders' / 'members', this is the right tool; if they asked about 'beneficial owners' / 'who controls', call `get_persons_with_significant_control` instead.
UK Companies House does not expose shareholders (members) as a structured API field. Shareholder data is filed inside two kinds of documents:
• latest_shareholder_filing - the most recent filing that carries a members-list snapshot. Post-2016 this is a CS01 'confirmation-statement-with-updates'; pre-2016 it is an AR01 annual return whose description ends in 'full-list-shareholders' (the statutory triennial full list under the old regime). Check the `description` field to know which format the attached document is in. Null means neither is on record - e.g. very new company, PLC whose register is kept by a third-party registrar like Equiniti, or a company that has only ever filed 'with-no-updates' CS01s and 'no-member-list' AR01s.
• incorporation_filing - the company's IN01 form. Its 'Statement of capital and initial shareholdings' section names the founding subscribers with share counts and nominal values. For companies with no shareholder filing on record (e.g. within the first 12 months after incorporation, before the first review period), IN01 is the authoritative and most current shareholder list available.
Pass the filing's document_id to fetch_document to retrieve the PDF/XHTML and extract shareholders from the document content.
For LSE-listed PLCs whose register is not at Companies House, also check FCA's National Storage Mechanism (data.fca.org.uk/a/nsm) for TR-1 notifications of major holdings (>=3% voting rights). |
