How we approach skylight installation in Dunstable
Skylight installation in Dunstable means survey, supply and fit — new openings, extensions and fit-only work. We cover the LU6 district and the rest of Bedfordshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Dunstable, as anywhere, skylight installation is the usual choice for builders' projects and retrofits into finished roofs.
Neighbouring towns include Luton (7 km) and Leighton Buzzard (10 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Dunstable?
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. 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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight installation in Dunstable: questions
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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.
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 I need to be at home for the survey in Dunstable?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Dunstable?
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.
