How do I check planning history on a UK property?

You can check the planning history of any UK property by searching the relevant local planning authority's online register, or by using HouseData which aggregates planning data from 425+ local councils into a single search. Planning records include all applications (approved, refused, and pending), building control sign-offs, and enforcement notices.

Three ways to check planning history

1. HouseData — search any postcode to see planning applications near the property, sourced from local authority feeds across England and Wales.
2. Local council website — visit your local planning authority's website and search by address or postcode. Most councils publish their planning register online.
3. Planning Portal — the Planning Portal provides links to all local authority planning registers.

What planning records show

Record type	What it tells you
Full planning application	Extensions, new builds, change of use
Householder application	Domestic alterations (loft conversions, garages)
Listed building consent	Works to listed or heritage properties
Building control	Compliance certificates for structural works
Enforcement notice	Unauthorised development flagged by the council

Why planning history matters

Checking planning history is essential before buying a property. It reveals whether extensions or conversions were carried out with proper permission, and whether any enforcement action is outstanding. HouseData's risk scoring methodology factors planning history into its overall property risk assessment.
