Replacement roof lanterns for Cheltenham homes
Swap a tired, leaking or polycarbonate lantern for modern double glazing.
In midsummer the noon sun stands about 61.5° high over Cheltenham, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Supply only or a fitting quote
- Often a one-day swap on a sound kerb

Planning and building regulations for Cheltenham
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Cheltenham are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Cheltenham
My old lantern leaks. Is it the lantern or the roof?
Often the roof or kerb detailing. A survey or close inspection will tell. If the lantern is the problem, replacing it is usually better value than repairing old polycarbonate.
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
How quickly can I get a roof lantern in Cheltenham?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for GL50.
Is it worth having solar-control glass in Cheltenham?
With the midsummer sun about 61.5° high at noon, roof glass in Cheltenham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
