Captured from Homedata's API and Lead Source on 17 Oct 2026. Solar figures are estimates from the roof's size and pitch. Rent is an estimate from nearby lettings. Its listing photos were tagged by an AI image model, 30 Sep to 3 Oct 2026: room types read at 80% confidence or more; the model's other tags are not shown. Price growth is for the NR7 district, not this home: the median sold price over the year to 22 May 2026 against the year before, captured 18 Oct 2026. Trees, ground movement and clay from our ground stability data, captured 18 Oct 2026: tree heights are measured, root reach is inferred; ground movement is the nearest satellite reading, for the area rather than this building.
* API data pre-screens: does not replace regulated CON29 or HMLR official searches where required by lender or insurer.

Worked example
The Conveyancing Association's BASPI form and HMLR's Digital Registration Service are driving a shift toward pre-populated property information at point of instruction. The Homedata API provides the structured data layer that makes this possible:
GET /properties/10023456789/summary/
Authorization: Api-Key YOUR_KEY
{
"uprn": "10023456789",
"address": "14 Thornton Road, Bristol, BS7 8EJ",
"tenure": "freehold",
"title_number": "AV12345",
"epc_rating": "D",
"council_tax_band": "E",
"flood_risk": {
"zone": "1",
"surface_water": "low"
},
"planning": {
"conservation_area": false,
"listed_building": false
}
}

Conveyancers use property data APIs to automate searches that traditionally required manual HMLR lookups or local authority search submissions. Common use cases include: verifying the registered proprietor at instruction, checking tenure (freehold/leasehold), screening flood and environmental risk, retrieving planning constraint status, and pulling sold price comparables for valuation reports. The Homedata API returns all of these for any UPRN in England and Wales in a single integration.
No: regulated CON29 local authority searches must be obtained from the relevant local authority or a licensed personal search company and cannot be replaced by API data alone. However, API data can pre-screen properties before searches are ordered (reducing wasted spend on abortive matters), populate BASPI and TA6 property information forms, and flag risk factors for early client disclosure.
BASPI (Buying and Selling Property Information) is the standardised property information questionnaire developed by the Conveyancing Association and HMLR as part of the Digital Property Logbook initiative. Pre-population means using API data to automatically fill known fields (address, UPRN, EPC rating, tenure, council tax band, flood risk zone) before sending the form to the seller, reducing form completion time from hours to minutes.
