Built by people who process completions, not just data.
Homedata is a product of the HM Haus Group — a UK property technology company that has spent years aggregating and structuring UK property data. We built the data layer that powers property search, listing intelligence, and market analytics at scale.
Built out of necessity
— The Homedata Team
Homedata started because UK property data is a mess. To assemble one usable property record we were stitching together half a dozen obscure APIs — one for addresses, another for sold prices, separate ones for EPC, environmental risk, planning, council tax. Each had its own auth, its own rate limits, its own field names, its own update cadence.
Market data — the most useful part — was basically non-existent.
Listing events, days on market, price reductions, withdrawal patterns, sold-vs-asking ratios — the signals that actually move a deal — weren't in any of the public feeds. And the bits that did exist sat behind silently inconsistent UPRN matching: the same property could be a different identifier in two feeds, or missing entirely from one. Records didn't line up. Fields conflicted. Joining a sold price to an EPC to a flood-risk score reliably took weeks of glue code per integration, and the joins broke quietly when an upstream schema shifted.
We built Homedata to fix that for ourselves. One licensed feed covering 90%+ of the UK property market, one canonical UPRN, every record matched and reconciled, every endpoint returning the same shape. The free tier is here because we wanted other developers to skip the work we had to do.
Why we built this
The HM Haus Group has been operating property platforms and working with estate agents across the UK for years. Listing portals, agent tools, property data — we know the space inside out.
Over that time, we accumulated something valuable: deep, structured data on UK properties — Land Registry records, EPC data, environmental risk scores, market activity data, and much more.
We combined that with public data sources — the EPC register, OS AddressBase, MHCLG deprivation indices, environmental risk datasets — and built a single API that returns everything a developer needs about any UK property.
Homedata is the result. Not a data reseller. Not a wrapper around Land Registry. A property data API built by a team that lives and breathes property technology.
What makes us different
Property & market intelligence. We combine property records, pricing history, and market activity data so developers can monitor changes without stitching together multiple sources.
UPRN-anchored. Every record tied to a Unique Property Reference Number from OS AddressBase. No geocoded approximations.
Self-serve from day one. Sign up, get a key, make a call. No sales demos, no procurement cycles, no six-week onboarding.
One API, not three. EPC, risk scores, price history, and property data in a single call. No stitching together multiple providers.
