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 copying data from 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?
No: there is no free tier and no free allowance. Homedata is pay as you go (100 tokens = £1, no subscription needed). Every account includes address lookup, property details, EPC ratings, council tax band, sold price history, and broadband speed data.
How does token pricing work?
Most endpoints cost 1 token. Address match costs 5 tokens on success; comparables are arranged per customer rather than sold at a fixed weight. 100 tokens = £1, bought as prepaid top-ups that never expire: your first is matched, and an optional monthly subscription earns bonus tokens. Spend them across any endpoint combination. No per-property charges.
Can I try the API before committing?
Absolutely. Sign up (no subscription needed) and your first top-up is matched 100%: £20 becomes 4,000 tokens. 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. Authentication is via API key in the Authorization header.
