Data Sources & Methodology

PlanningScout covers active local planning authorities in England. We use open public-sector datasets and do not manufacture estimates for authorities where a dataset has no coverage.

A dash (—) on a council page means the source dataset does not currently cover that authority. It does not mean the true count is zero.

Live constraints checker methodology

The Planning Constraints Checker sends the entered England postcode or UPRN to the official Planning Data API and requests current intersecting records from selected heritage, environmental, flood, Green Belt, Article 4 and protected-tree datasets. PlanningScout displays returned records without creating inferred designations.

  • Coverage varies by dataset and local planning authority.
  • A postcode represents an area and may not match the exact red-line site boundary.
  • No returned record does not mean that no constraint exists.
  • The council's own constraints map, planning history and source designation remain the final checks.

Planning Data platform

Live and bulk England planning datasets used for council records and the constraints checker. Coverage limitations are shown with results.

Corrections

Public datasets change and local authority boundaries can be reorganised. If a council link, count or planning rule looks wrong, send the page URL and the supporting source.
