Companies House

UK government register of companies. Search and retrieve company data including profiles, officers, filing history, and charges.

Data Model

  • Company Search — search by name, returns paginated results with company_number, title, address, status, date_of_creation.
  • Company Profile — full profile by company_number: registered office, SIC codes, accounts dates, confirmation statement dates, status, type.
  • Officers — list of current and resigned officers (directors, secretaries) with appointment dates, roles, nationality.
  • Filing History — chronological list of documents filed (annual accounts, confirmation statements, appointments). Each has a description, date, and optional document links.
  • Charges — secured charges/mortgages registered against the company, with status, created/delivered dates, and persons entitled.

Gotchas

  • Company numbers: Always 8 characters, zero-padded (e.g. '00000006' for oldest company). Scottish companies start with 'SC', Northern Irish with 'NI'.
  • Rate limits: 600 requests per 5 minutes per registered application (vendor-documented).
  • Pagination: Uses start_index (0-based) and items_per_page. Default page size varies by resource type.
  • Filing documents: Filing history items may have links.document_metadata for downloadable PDFs (requires separate document API).
