uk_psc — UK persons with significant control of companies (Companies House, 2026)

Description

The network of the persons with significant control (PSC) of the companies of the United Kingdom, from the PSC register of Companies House, the UK registrar of companies. Since 2016, UK companies and limited liability partnerships must report the individuals and legal entities that have significant control over them (more than 25 % of the shares or votes, the right to appoint or remove the majority of the board, or significant influence or control otherwise), and since 2022 the overseas entities that own UK property must report their registrable beneficial owners. The network is built from the daily snapshot of the register of 31 October 2026 (the snapshot is replaced every day), and contains both the current controllers and those that have ceased (with their date of cessation), 15,174,793 records in all.

Each directed edge goes from a controller to the company that it controls, with the nature of the control. The companies are identified by their company number, and described by the "Free Company Data Product" of Companies House of 1 October 2026 (name, category, status, dates, postcode, SIC codes); the companies that are not in it (e.g. dissolved long ago) only have their number. The controllers that are legal entities registered in the UK (corporate PSCs whose registration number is that of a UK company) are the same nodes as the companies themselves, so that the network contains chains of control between UK companies; the other corporate controllers are identified by their name, registration number and country of registration. The register gives no identifier of the individuals: they are merged by their name (forenames, middle names and surname, without titles, upper-cased) and month and year of birth (the day of birth is not public), so that two persons with the same name born in the same month are taken as one, and the same person with differently written names (or a wrong date) is split into several nodes. Legal persons (e.g. governments, which have no registration number) are merged by name, legal form and legal authority. The "super-secure" PSCs, whose details are withheld for their protection, are one node each (without any data). The statements of companies that have no registrable PSC, and the exemptions, are not included.

The network has the following properties:

  • (Node) kind: company (a UK company or overseas entity of the register), individual, corporate_entity (a legal entity that is not a UK company), legal_person, super_secure.
  • (Node) company_number (companies): the company number at Companies House (its page is https://find-and-update.company-information.service.gov.uk/company/<company_number>).
  • (Node) name: the name of the company, of the individual (as given in the first record), or of the legal entity.
  • (Node) birth_month, birth_year (individuals): the month and year of birth (-1 if not given).
  • (Node) nationality, country_of_residence (individuals): as given in the first record.
  • (Node) registration_number, legal_form, legal_authority, country_registered (corporate entities and legal persons): their identification, as given.
  • (Node) company_category, company_status, country_of_origin, incorporation_date, dissolution_date, postcode, sic_codes (companies in the company data): the category (e.g. Private Limited Company), the status (e.g. Active), the country of origin, the dates of incorporation and dissolution (YYYY-MM-DD), the postcode of the registered office, and the SIC codes of the activities (e.g. 99999 - Dormant Company).
  • (Edge) psc_kind: the kind of record (e.g. individual-person-with-significant-control, corporate-entity-person-with-significant-control, individual-beneficial-owner for the beneficial owners of overseas entities).
  • (Edge) natures_of_control: the natures of the control (e.g. ownership-of-shares-75-to-100-percent, voting-rights-25-to-50-percent, right-to-appoint-and-remove-directors, significant-influence-or-control).
  • (Edge) notified_on, ceased_on: the dates on which the control was notified and ceased (YYYY-MM-DD; empty if it has not ceased).
  • (Edge) ceased: whether the control has ceased.
  • (Edge) is_sanctioned: for beneficial owners of overseas entities, whether they are under sanctions (1, 0, or -1 if not given).
