Am I in a conservation area?
Enter a full postcode in England to see whether it lies inside a conservation area, which one, and what that means for heat pumps, solar panels, wall insulation and windows. Boundaries: councils via planning.data.gov.uk, 3 November 2026.
How the checker answers
- Inside — the centre of the postcode (ONS Postcode Directory) lies inside a conservation area boundary, or every home in the postcode with an energy certificate does.
- Partly — some homes in the postcode are inside and some are not: the boundary runs through it. Check your own address on the council's map.
- Not found — neither the centre of the postcode nor any home in it with an energy certificate lies inside a conservation area in the data. That is not a guarantee: a council's own map is the legal record.
For each area found you get its page: the rules for heat pumps, solar panels, wall insulation and windows there, any Article 4 direction we found, listed buildings and the homes inside by energy certificate. 209,935 postcodes in England have their centre (189,878) or at least one certified home inside a conservation area.
