If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos from Bletchley (MK3) and we'll tell you which it is — with the price agreed in writing before any work.

What usually causes it?
Clear or standard Low-E glass
Standard units let a lot of solar heat through; solar control coatings reflect more of it.
No ventilation
A lantern without opening vents traps warm air at ceiling level.
Covering Bletchley and nearby
Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.
We cover Bletchley as part of Buckinghamshire, about 13 miles from Aylesbury.
Neighbouring places we cover include Milton Keynes (3 miles), Leighton Buzzard (6 miles), Ampthill (10 miles).
How much should it cost?
Guide price for solar control and self-cleaning glass upgrades: £345–£895 ex VAT (£414–£1,074 inc 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.
