UK Property Data API for PropTech Developers
Stop integrating with eight different government portals and managing eight API keys. Homedata gives PropTech developers a single REST API for Land Registry, EPC, planning, flood risk, AVM valuation, and 20+ datasets, with consistent JSON response shapes and UPRN-keyed joins.
What you can build
Property portals
Enrich listings with EPC, flood risk, school ratings, and council tax: surface data buyers care about without building your own data pipeline.
Valuation tools
AVM valuations with confidence scores and comparable evidence: instant automated estimates for any UK UPRN.
Due diligence platforms
Bundle flood risk, leasehold, planning history, and ownership data into structured property reports for professionals.
Mortgage calculators
Pull council tax, EPC band, and flood risk data at the point of application to support underwriting automation.
Property search tools
Radius search for planning applications, comparable sales, and EPC data: building neighbourhood context into search.
Investment analysis tools
Combine AVM, comparable sales, rental yield, and area demographics to build data-driven investment scoring.
