UK Government Property Data API
Instead of integrating with 8 different government data portals (Land Registry, MHCLG EPC register, DLUHC planning data, council tax records, DfE schools, ONS census, Environment Agency flood data) Homedata consolidates them into a single REST API with consistent authentication and response format.
What's in the API
Land Registry
Sold prices (1995–), title records, tenure, proprietor
Explore →EPC Register
Over 23M certificates held, ratings, floor area, construction age
Explore →Planning Applications
Nearly 4M geocoded applications from 300+ LPAs
Explore →Council Tax
Council tax band for properties in England, Wales and Scotland
Explore →Schools (DfE GIAS)

Explore →Postcode Data
ONS postcode directory: coordinates, LSOA, ward
Explore →Companies House

Explore →One API key, all datasets
Government data portals require separate registrations, have inconsistent APIs, and often have rate limits that make bulk work impractical. Homedata normalises all datasets behind a single API key with predictable call-weight billing.
- Single authentication header
- Consistent JSON response shape
- UPRN-keyed: join any dataset to any other
- Dedicated support for integration questions

FAQ
Is this the same data as the government portals?
Yes: we source directly from HM Land Registry, MHCLG, Environment Agency, DfE, ONS, and other official open data releases. We normalise, UPRN-link, and serve via a clean REST API.
What happens to EPC data after May 2026?
The government's free EPC portal closes 30 May 2026. Homedata's EPC endpoint will continue operating with the same data. Migrate before the shutdown to avoid service interruption.
Can I combine multiple datasets per property?
Yes, all datasets share the UPRN as a common key. Call the property intelligence endpoint to get EPC, risk scores, price history, and planning data in a single response.
