In Cambridge, 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.

Signs you need commercial roof lantern repairs

Common causes we find
Access

Deferred maintenance
Leaks appear when maintenance has slipped.
Roof lanterns in Cambridge
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
If you're just outside Cambridge, we also cover Newmarket (13 miles), Ely (15 miles), Huntingdon (16 miles).
How much should it cost?
Typical range: £495–£2,995 ex VAT, which is £594–£3,594 with 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
