The best UK property data APIs in 2026: compared

Where things stand in 2026

UK property data APIs have grown rapidly since 2020. Government open data releases (Land Registry Price Paid, MHCLG EPC register, Environment Agency flood risk, OS Open UPRN) have made the underlying data freely available, but accessing it reliably at scale and as structured JSON still requires an aggregation layer. That is what the providers below offer.

Choosing by use case

Start from the job, not the provider. Most teams need one of these:

• Address lookup on a form only. Ideal Postcodes or Loqate. Both sell pay-as-you-go credits and charge only when a full address is returned.
• An address plus the facts about the property (EPC, sold prices, flood risk, title, council tax) in one call. Homedata or Street Data, both pay as you go.
• Investment metrics by area (yields, rents, growth, demand). PropertyData.
• Branded property reports for agents, surveyors and brokers. Sprift.
• Site sourcing, planning and land ownership on a map. Searchland.
• Australian addresses. getAddress, which no longer lists UK data.

For address lookup only, Ideal Postcodes or Loqate. For investment metrics such as yields and growth, PropertyData.
