Planning, building control and Tonbridge
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.
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.

Questions about glass links & glass box roofs in Tonbridge
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Is structural glass safe?
Structural glass is laminated so it stays in place if a ply breaks. The manufacturer designs it for the loads involved.
Is the survey in Tonbridge free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
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.
