What does skylight replacement in Bexley involve?
Skylight replacement in Bexley means replacing tired domes and failed glass with a modern rooflight. We cover the DA5 district and the rest of Greater London, with a survey before any price is fixed.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Skylight replacement suits older extensions due a modern rooflight.

Planning and building rules for Bexley
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.
