Flat rooflights for Whitstable homes
A single near-flat pane on an upstand: minimal, low and discreet.
In midsummer the noon sun stands about 62.1° high over Whitstable, 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
- Minimal, frameless-looking from inside
- Usually cheaper than a lantern

Planning and building regulations for Whitstable
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 Whitstable 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.
