What does skylight installation in Sherborne involve?
Our skylight installation service in Sherborne 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.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. In Sherborne, as anywhere, skylight installation is the usual choice for new extensions, new openings and fit-only jobs.
Sherborne sits about 8 km from Yeovil and 26 km from Dorchester, and we cover the whole DT9 postcode district and the roads in between.

Consents for skylight installation in Sherborne
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
How long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Is the survey free?
Yes, for new installations. Repair visits are charged.
How do I book a survey in Sherborne?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Sherborne?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
