Property Ownership Data API UK
Land Registry title data in a single API call. Pass a UPRN in England and Wales to get the title number, tenure, estate interest and title class, with the title boundary as GeoJSON. Used by conveyancers, mortgage lenders, property sourcing tools, and PropTech platforms building due diligence and portfolio intelligence workflows.
What's in the API
Title number
The HMLR title number for the registered title
Tenure
Freehold or leasehold, as registered at HM Land Registry
Estate interest
The registered estate, with its HMLR interest code
Title class
Quality of title, such as absolute freehold, with its HMLR class code
Title boundary
The registered extent as a GeoJSON polygon, ready to map
Title records, keyed to UPRN
Land Registry title data normally means an HMLR account, a title search per property and a polygon you have to georeference yourself. Pass a UPRN and get the registered title back as GeoJSON, already joined to the address.
- UPRN-keyed: join to any other Homedata dataset
- Tenure, estate interest and title class in one response
- Registered extent as a GeoJSON polygon, ready to map
- HMLR interest and class codes alongside the plain-English labels
- Restrictive covenant flag and record status

Can I look a title up by anything other than UPRN?
This endpoint is keyed on UPRN. If you are starting from an address or a postcode, resolve it first with the address endpoints, then pass the UPRN through. Every account reaches this endpoint: a monthly subscription simply earns bonus tokens for higher-volume work.
Which properties are covered?
Registered titles in England and Wales. HM Land Registry does not hold titles for Scotland or Northern Ireland, which have their own registers.
What if the property is unregistered?
Not every property in England and Wales has a registered title, and where there is no title there is nothing to return. The API never infers a title that HM Land Registry does not hold.
