Am I in a Conservation Area?

Enter your address to check whether your property sits within a conservation area, AONB, National Park, Article 4 direction, or other designation — and find out exactly what this means for your permitted development rights before you start your project.

What this tool checks

Enter your address below. The tool queries three live government datasets to check five types of designation:

Conservation area
Restricts side extensions, cladding, roof changes visible from highway
AONB / National Park
Same PD restrictions as conservation areas
Listed building
Most works need Listed Building Consent in addition to planning permission
Article 4 direction
Removes specific PD rights — check what is listed in the direction

Green belt is also shown, though it does not change PD rights for home improvements. Data is sourced from MHCLG Planning Data and Natural England.

Check your address

Start typing your full address or postcode. Select your property from the dropdown to run the designation check — results appear within a few seconds.

About these checks

  • Conservation areas are designated by local planning authorities. Data comes from the MHCLG Planning Data platform. Some councils may not have fully uploaded their boundaries — always confirm with your LPA.
  • AONBs and National Landscapes are designated by Natural England and carry the same PD restrictions as conservation areas for home extensions.
  • Article 4 directions vary by area — the specific rights removed differ between directions. Always read the actual direction text from your council to understand what is and is not affected.
  • Listed buildings require Listed Building Consent for most works regardless of whether planning permission is also needed. This applies to all grades (Grade I, II*, and II).
  • This tool is a guide only. For certainty, apply for a Lawful Development Certificate (£262) or consult your LPA before starting work.
