Is it free to find out who owns a property in the UK?

A basic title register search via HM Land Registry costs £3 per title. You can search by address or title number. For free bulk access, the Land Registry publishes an open dataset of England and Wales registered titles, but this is less current and does not include full proprietor details for commercial titles.

Can I find property ownership details via API?

Yes. The Homedata ownership API returns proprietor names, tenure (freehold/leasehold), title class, and date of registration for any UPRN in England and Wales. A single GET request to /api/properties/{uprn}/ownership/ returns this data in JSON format with sub-200ms response times.

Does every property in England and Wales have a Land Registry title?

No. Approximately 15% of property in England and Wales is still unregistered — typically older properties that have not changed hands recently. Registration is compulsory on sale, mortgage, or certain other triggers. For unregistered properties, ownership must be established via deeds held by the owner or their solicitor.

How to Find Out Who Owns a Property in the UK

Q: How do I find out who owns a property in the UK?

The most reliable method is to search HM Land Registry's title register at landregistry.data.gov.uk. A title register search costs £3 and returns the registered proprietor's name. For programmatic access at scale, the Homedata ownership API returns the same data via a REST call for any UPRN in England or Wales.

Where property ownership data comes from

In England and Wales, property ownership is recorded by HM Land Registry (HMLR). When a property is sold, mortgaged, or transferred, the transaction is registered, and HMLR updates the title register to show the new proprietor. This is a public record — anyone can pay £3 to view a copy.

Scotland uses the Registers of Scotland (£3 per search), and Northern Ireland uses the Land Registers of Northern Ireland. This guide focuses on England and Wales.

The £3 manual route

Visit landregistry.data.gov.uk and search by address or postcode. Select the correct title from the results and pay £3 to download a PDF title register. This shows:

Registered proprietor name(s)
Tenure (freehold or leasehold)
Title class (absolute, good leasehold, qualified, possessory)
Price paid on last registration (where applicable)
Charges registered (mortgages, restrictions)

This works well for one-off lookups but is not scalable for applications needing to check thousands of properties.

Ownership data via the Homedata API

For developers, conveyancers, and proptech companies needing programmatic access, the Homedata API wraps HMLR's title data and returns it as structured JSON. A single call to /api/properties/{uprn}/ownership/ returns the registered proprietor, tenure, title number, and date of registration.

GET /api/properties/10023456789/ownership/
Authorization: Api-Key YOUR_KEY

{
  "uprn": "10023456789",
  "title_number": "AV12345",
  "tenure": "freehold",
  "proprietor": "Smith, James Robert",
  "title_class": "absolute",
  "registered_date": "2019-04-11",
  "country": "England"
}

What ownership data doesn't tell you

Unregistered properties (~15% of England and Wales) do not appear in HMLR's digital register. Ownership must be established via physical deeds.
Company ownership — many investment properties are owned by companies or SPVs. The proprietor field shows the company name; Companies House must be checked separately for directors and shareholders.
Beneficial ownership — trusts and nominee arrangements mean the registered owner may differ from the beneficial owner.
Scotland and Northern Ireland — separate registers; the Homedata API covers England and Wales only.

Use cases for ownership API access

Conveyancers — verify title at instruction without manual HMLR searches.
Mortgage lenders — confirm proprietor against applicant name as part of AML/KYC workflow.
Estate agents — verify the seller is the registered owner before taking instructions.
Proptech developers — build property intelligence tools that surface ownership history alongside price paid and EPC data.

Pricing

Ownership lookups via the Homedata API cost 1 call per UPRN. The free tier includes 100 calls/month. Production plans start at £49/month.
