Skylight installation for Gerrards Cross: the essentials
We handle skylight installation across Buckinghamshire, including Gerrards Cross. In short: survey, supply and fit — new openings, extensions and fit-only work. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of skylight installation for builders' projects and retrofits into finished roofs.
Gerrards Cross sits about 3 km from Chalfont St Peter and 7 km from Uxbridge, and we cover the whole SL9 postcode district and the roads in between.

Planning, building control and Gerrards Cross
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Our planning guide covers each nation in more detail.
