Built for AI agents
Your AI agent can now look up any home.
Homedata works inside Claude, Codex and the agents you already use. Paste one message with your key and your agent can check a home's energy, flood risk, schools and prices, and tell you where every answer came from.
Install the Homedata MCP server (npx -y homedata-mcp) with my API key, YOUR_API_KEY, then find 63 Harvey Lane, Norwich to check it works.

Built by a property data company. Not a data reseller.
Most property data APIs cobble together a few public datasets. With 29 million UK properties covered, Homedata combines UPRN-matched records, market activity data and authoritative public records, all behind a single API.
-
Live listing intelligenceProperty-level market activity, price changes, new listings and status signals in one place.
-
UPRN-precise by defaultEvery record anchored to a Unique Property Reference Number. Address-matched from OS AddressBase, not geocoded approximations.
-
One API. Not three.EPC data, risk scores and price history in a single call. No stitching together an address provider, the EPC register and a flood risk service.
-
Self-serve. No sales calls.Sign up, get a key, make a call. No demo, no contract, no procurement process.

Check one property, no account needed
Public records, one property at a time. No tokens.
Why we built this
Market data, the most useful part, was basically non-existent.
So we built it: one licensed feed, one canonical UPRN, every record matched and reconciled, every endpoint returning the same shape.
Read why we built Homedata →What is a property data API?
A property data API lets developers query UK property information (EPC ratings, sold prices, flood risk, council tax, planning history) as structured JSON via HTTP. Integrate once; get clean data in real time for any of 29 million properties.
What UK property data is publicly available?
Land Registry Price Paid (sold prices), MHCLG EPC register, Environment Agency flood risk maps, VOA council tax bands, OS Open UPRN, and planning.data.gov.uk are all open data. Homedata aggregates them into one normalised API.
How many properties does the Homedata API cover?
29 million UK properties covered, identified by UPRN. We hold over 23 million EPC certificates for England and Wales. Sold price history covers England and Wales back to 1995.
What is the difference between Homedata and Land Registry?
HM Land Registry is a government body that registers property ownership in England and Wales and publishes Price Paid transaction data as open data. Homedata is a commercial API that combines Land Registry, EPC, flood risk, planning, AVM, and listing event data into a single developer-friendly JSON API.
How do I get started with the Homedata API?
Sign up (no subscription needed), get your API key instantly, and make your first call: GET /address/match/?address=10+Downing+Street&postcode=SW1A+2AA. Full docs, code examples, and a live playground are included.
