Data coverage

Homedata covers homes and businesses in England, Wales, Scotland and Northern Ireland that receive post. If something has no postal address, we don't hold it, and the API says so rather than guessing.

What we cover

  • Postal addresses in the UK. Residential and commercial addresses in England, Wales, Scotland and Northern Ireland that receive post, each with its UPRN.
  • Land Registry titles for England and Wales. Scotland's titles are held by a different registry and aren't included.
  • Some datasets cover less than Great Britain, for example flood zones cover England. Those endpoints say so in the answer, in query.coverage and query.in_coverage, and an answer outside coverage on those endpoints is not charged.

What we don't cover

  • Land parcels and fields, such as a paddock, a farm field or a plot with no postal address.
  • OS grid references, such as TL4256 5508 or TL 42565 55080. Address lookup matches postal addresses only. We spot grid references and say so with looks_like_grid_ref.
  • Non-postal UPRNs. Ordnance Survey gives UPRNs to things that never get post: street furniture, car parks, field boundaries. We only hold UPRNs for postal addresses, so the others get uprn_not_found, free of charge.

Coverage details for a particular dataset are available on request. Contact us for the latest, or see Errors for what each answer means.
