Frequently asked questions
What is a property data API?
A property data API is a programmatic interface that lets developers query UK property information — addresses, EPC ratings, sold prices, flood risk, council tax, planning applications, schools, and more — directly from their applications. Instead of scraping websites or buying static datasets, you make HTTP requests and get structured JSON responses in real time.
How many UK properties does Homedata cover?
Homedata covers 29 million UK properties identified by their Unique Property Reference Number (UPRN). This includes residential and commercial properties across England, Wales, and Scotland.
Is there a free UK property data API?
Yes. Homedata offers a free tier with 100 API calls per month, no credit card required. The free tier includes address lookup, property details, EPC ratings, council tax band, sold price history, and broadband speed data.
How does the call-weighted pricing work?
Most endpoints cost 1 API call. Address lookup costs 2 calls. Comparables analysis costs 10 calls. Your monthly plan includes a set number of calls — use them across any endpoint combination. No per-property charges.
Can I try the API before committing?
Absolutely. Sign up for the free tier (no credit card) and get 100 calls/month. The Starter tier also includes a 14-day free trial. We also offer a live playground in your dashboard where you can test any endpoint with real data.
What format does the API return?
All endpoints return structured JSON over HTTPS. We also support CSV and JSON bulk export for Growth tier and above. Authentication is via API key in the Authorization header.
