How we approach skylight installation in Darlington
Skylight installation in Darlington means survey, supply and fit — new openings, extensions and fit-only work. We cover the DL3 district and the rest of Durham, with a survey before any price is fixed.
Many North East homes have loft rooms that benefit from larger roof windows with blackout blinds. Skylight installation suits new extensions, new openings and fit-only jobs.
We cover all of Darlington and the DL3 district, and nearby Newton Aycliffe and Stockton-on-Tees.

Planning, building control and Darlington
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. 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. 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.

Common questions
Is the survey free?
Yes, for new installations. Repair visits are charged.
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.
Will I need planning permission in Darlington?
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.
How do I book a survey in Darlington?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
