In Caerphilly, 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.

Covering Caerphilly and nearby
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
We cover Caerphilly as part of Gwent, about 9 miles from Newport, Gwent.
Close by, we also cover Risca (6 miles), Pontypridd (6 miles), Blackwood (6 miles).
Guide prices for commercial roof lantern repairs in Caerphilly
Guide price for commercial roof lantern repairs: £495–£2,995 ex VAT (£594–£3,594 inc 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 Wales?
In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
