Skylight installation in Seaford: what is involved?
Skylight installation in Seaford means survey, supply and fit — new openings, extensions and fit-only work. We cover the BN25 district and the rest of East Sussex, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Skylight installation suits builders' projects and retrofits into finished roofs.
Seaford is around 18 km from Brighton, and we survey and fit throughout that part of East Sussex, including the BN25 district.

Planning and building rules for 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Skylight installation in Seaford: questions
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Do you offer skylight installation in Seaford?
Yes. We carry out skylight installation in Seaford and across East Sussex. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Seaford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
