What To Check Before You Rely On The Answer

Page type

Data/tool landing page

Legal scope

England-first scaffold unless a record states a devolved-country source.

What changes the answer

The page should only become fully indexable where source URLs, update dates and methodology are present.

Official-source basis

Council validation requirement pages and Planning Portal submission guidance.

When general guidance stops being enough

Do not rely on this scaffold as a complete local answer until the individual council row has been source-checked.

Source And Update Method

Launch phase: Phase 5

Status: Scaffolded; local validation notes must stay tied to council source URLs and update dates.

Source basis: Council validation requirement pages and Planning Portal submission guidance.
