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

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.
