Homes within 1 km whose energy certificates show the floor area growing: extensions, loft and garage conversions. Tap a home on the map or in the list for its full history. Back to HD4 6TY
Not every extension shows here. We only see building work when a new energy certificate is lodged, which happens when a home is sold, let or newly built. A loft or extension added since then won't appear, even with planning permission and building control sign-off, because those records aren't published as open data outside London. Missing work doesn't mean missing paperwork.

From energy performance certificates (MHCLG): a later certificate shows at least 15 m² and 15% more floor area than an earlier one (and no more than 2.5 times, to leave out typing errors). Some changes come from a more careful measurement rather than building work. Addresses: HM Land Registry. Contains HM Land Registry data © Crown copyright and database right 2026, OGL v3.0.
