What do sliding rooflights in Frome involve?
For Frome homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for sliding rooflights include walk-out access where a hatch would feel cramped.
Frome is around 17 km from Bath, and we survey and fit throughout that part of Somerset, including the BA11 district.

Planning, building control and Frome
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.
Read the planning permission guide before you commit to a design.

Questions about sliding rooflights in Frome
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
How do I book a survey in Frome?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Frome?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
