London Conservation Area Checker
Look up any London postcode, search by conservation area name, or pick a borough. The tool returns the conservation area, its Article 4 scope, the council that decides applications, and direct links to the relevant appraisal and our specialist heritage planning advice.
Uses postcodes.io. We do not store your address. For the authoritative boundary, confirm on the borough's interactive planning map.
