Skylight replacement for Ewell: the essentials
We handle skylight replacement across Surrey, including Ewell. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Ewell, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
Ewell sits about 3 km from Epsom and 4 km from Banstead, and we cover the whole KT17 postcode district and the roads in between.

Planning and building rules for Ewell
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.
