Skylight installation for Tonbridge: the essentials
For Tonbridge homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
We work across Kent, including Tonbridge, and in neighbouring towns such as Tunbridge Wells and Sevenoaks. Access, parking and how the glass reaches the roof are all checked at the survey.

What to check first

Planning and building rules for Tonbridge
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. 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.

Questions about skylight installation in Tonbridge
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 you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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 Tonbridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Tonbridge?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
