Roof lantern replacement in Greater London

Across Greater London — Westminster, Islington, Bexley and beyond — we replace lanterns that are beyond economic repair, checking the kerb and re-making the junction. Photos first, then a written fixed price.

We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed. We carry out roof lantern replacement across Greater London, with a guide price from your photos and a fixed price in writing before any work starts.

Roof lanterns in Greater London

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.

Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.

What should you expect to pay for roof lantern replacement in Greater London?

Guide price, supplied and fitted£1,995–£4,995 ex VAT£2,394–£5,994 inc VAT

Most roof lantern replacement jobs come in between £1,995 and £4,995 ex VAT (£2,394–£5,994 including VAT), supplied and fitted. 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.
