Overview
Why skylights?
A skylight is the simplest way to bring daylight deep into a loft, landing or dark extension, because light from above reaches parts of a room that wall windows can't.
For pitched roofs we fit VELUX — our standard spec — and FAKRO as a value alternative. For flat roofs we fit bespoke Cambridge Skylights rooflights.

Good to know
Planning, regulations and timings
Planning permission
Rooflights in a pitched roof are usually permitted development if they don't project more than 150 mm above the roof slope. Listed buildings, conservation areas and front roof slopes facing a road can need consent, and cutting rafters needs Building Regulations approval. We check at survey.
Survey to installation
Typically 4–8 weeks from survey to installation, agreed with you up front. One named project manager runs your job from survey to sign-off, and our own fitters do the work — we don't subcontract glazing.
Questions
Skylights: your questions answered
How much does a skylight cost?
A VELUX or FAKRO roof window costs £900–£2,500 installed, with electric and solar models at the top end. A bespoke flat rooflight costs £1,800–£5,000. Indicative, supplied and installed in London and the South East, including VAT; prices updated 11 October 2026. A survey confirms the final figure.
VELUX or FAKRO?
VELUX is our standard spec for loft conversions and pitched roofs, with INTEGRA electric and solar options. FAKRO is a strong-value alternative, including FTT Thermo triple-glazed windows and fire-escape windows.
Do I need planning permission for a skylight?
Usually not, if it doesn't project more than 150 mm above the roof slope. Listed buildings, conservation areas and front roof slopes facing a road can need consent.
Can a skylight open and close automatically?
Yes. VELUX INTEGRA roof windows open electrically or by solar power, and a rain sensor closes them when it rains.
