If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos from Tonbridge (TN9) 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
- Glare on screens or worktops
- Furniture or flooring fading under the lantern
- Clear, uncoated glass in an older 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.
About Tonbridge and the TN9 area
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Tonbridge is around 12 miles from Maidstone, and both are within our Kent coverage.

How much should it cost?
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?
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.
