UK Property Intelligence · Developed by Talent Dragon Ltd

The Property Detective

A free reconnaissance tool for buyers. Type any UK postcode and house number — receive every public record we can pull.

EPC API credentials (optional but recommended)

To pull energy ratings, floor area, and £/sqft directly into the report, you need a free EPC API key. Sign up at epc.opendatacommunities.org — they'll email a key. Stored locally in this browser only; never sent anywhere except the EPC API.


Companies House API key (optional)

To pull every company registered at this address directly into the report. Free — sign up at developer.company-information.service.gov.uk and create an "API client" in the dashboard. Note: Companies House blocks browser requests, so the call is routed through the public CORS proxy corsproxy.io — your key passes through it. If that's a concern, leave blank and the section will fall back to a deep link.
