How we approach skylight installation in Godalming
Our skylight installation service in Godalming covers survey, supply and fit — new openings, extensions and fit-only work. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
Godalming sits about 6 km from Guildford and 12 km from Aldershot, and we cover the whole GU7 postcode district and the roads in between.

Consents for skylight installation in Godalming
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight installation in Godalming
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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 fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Will I need planning permission in Godalming?
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.
Do I need to be at home for the survey in Godalming?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
