All 33 London boroughs · postcode-district reports
Planning Permission Checker covers all 33 London boroughs. Each borough guide carries the full list of conservation areas and Article 4 directions from official planning.data.gov.uk geometry, live house-price data and verified planning commentary; each district report drills into the local postcode area and links to service guidance for licences to alter, internal alterations, extensions, lofts, basements, garden rooms, purchase feasibility and listed or conservation works. For a specific house, run the address-level check — it tests your exact coordinates against the constraint boundaries.
