If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos from Holloway (N7) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need solar control and self-cleaning glass upgrades
- The room is noticeably hotter than the rest of the house in summer
- Glare on screens or worktops
- Furniture or flooring fading under the lantern
Common causes we find
Clear or standard Low-E glass
Standard units let a lot of solar heat through; solar control coatings reflect more of it.
Orientation
South- and west-facing lanterns gain the most heat in the afternoon.
Covering Holloway 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.
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.
We cover Holloway as part of Greater London, about 4 miles from Westminster.
If you're just outside Holloway, we also cover Highbury (1 mile), Archway (1 mile), Camden Town (1 mile).
What should you expect to pay in Holloway?
Most solar control and self-cleaning glass upgrades jobs come in between £345 and £895 ex VAT (£414–£1,074 including VAT), per glass unit. 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?
In England, 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, so we set out the route in writing first. 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.
