How we approach skylight replacement in Seaford
We handle skylight replacement across East Sussex, including Seaford. 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Seaford, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Seaford sits about 12 km from Rottingdean and 13 km from Eastbourne, and we cover the whole BN25 postcode district and the roads in between.

Consents for skylight replacement in Seaford
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
Read the planning permission guide before you commit to a design.
