Property Passport UK

See this information for your own home

Free address search across England and Wales. No account needed.

19.4 million searchable properties. EPC, flood risk, sold prices, planning, and more in one structured record per home.

Sources have different weight

Official datasets, seller statements, and agent marketing fulfil different jobs. Confusing them creates bad decisions.

Label what you know

When you keep notes, tag whether something came from Land Registry context, a PDF upload, or a conversation.

The product is designed to show provenance between official context and uploaded Documents when permissions allow.
