In Caterham, as everywhere, commercial lanterns and atrium rooflights fail in the same ways as domestic ones, but access, safety and disruption matter more. Send photos and we'll tell you what we think has failed.

Roof lanterns in Caterham
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

What should you expect to pay in Caterham?
Most commercial roof lantern repairs jobs come in between £495 and £2,995 ex VAT (£594–£3,594 including VAT), per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
