How we approach skylight replacement in Bentley
Skylight replacement in Bentley means replacing tired domes and failed glass with a modern rooflight. We cover the DN5 district and the rest of South Yorkshire, with a survey before any price is fixed.
Many Yorkshire homes have had kitchen extensions with flat roofs, where a larger glass rooflight is a straightforward upgrade from an old dome. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
We work across South Yorkshire, including Bentley, and in neighbouring towns such as Doncaster and Rotherham. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Bentley
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. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
