What the job involves
A new skylight install involves cutting an opening in the roof structure, trimming the rafters, fitting the frame, and flashing it into the surrounding covering. Velux is the dominant UK brand; Fakro and Keylite are credible alternatives at lower price points.
The structural work requires attention to rafter trimming — Building Regulations require any rafter that is cut to be supported by the trimmer either side. A structural calculation is sometimes needed on larger openings.
Cambridge — local context
Traditional material: Clay pantile (East Anglia tradition) and clay plain tile.
Central Cambridge has an exceptionally high density of listed buildings and college estates; Listed Building Consent is commonly required for re-roofs, and clay-based materials are almost always specified.

Do I need Building Regulations approval?
Yes, because structural rafters are being cut. A registered roofer or builder can usually notify Building Control or a private approved inspector. Smaller roof windows in existing rafter bays may be simpler; anything larger needs a structural sign-off.
Is Velux worth paying more for?
Velux spares and replacement parts are widely available for 30+ years, which matters when seals and gaskets eventually need replacing. Cheaper brands can be fine if you don’t mind replacing the whole unit when something fails.
