Flat rooflights for Cirencester homes
A single near-flat pane on an upstand: minimal, low and discreet.
In midsummer the noon sun stands about 61.7° high over Cirencester, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Very low profile from outside
- Usually cheaper than a lantern
- Fixed or electric opening versions

Planning and building regulations for Cirencester
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Cirencester 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.

Some ranges offer electric opening versions. Ask for availability for your size.
Do I need planning permission for a roof lantern in Cirencester?
