Commercial lanterns and atrium rooflights fail in the same ways as domestic ones, but access, safety and disruption matter more. Send photos from Harrow (HA2) and we'll tell you which it is — with the price agreed in writing before any work.

Covering Harrow and nearby
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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
We cover Harrow as part of Greater London, about 10 miles from Westminster.

What should you expect to pay in Harrow?
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.
