How we approach skylight installation in Caterham
Skylight installation in Caterham means survey, supply and fit — new openings, extensions and fit-only work. We cover the CR3 district and the rest of Surrey, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Caterham, as anywhere, skylight installation is the usual choice for builders' projects and retrofits into finished roofs.
We work across Surrey, including Caterham, and in neighbouring towns such as Coulsdon and Purley. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Caterham
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
