Flat rooflights for Chichester homes
A single near-flat pane on an upstand: minimal, low and discreet.
In midsummer the noon sun stands about 62.6° high over Chichester, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Single glazed unit with a slight fall
- Fixed or electric opening versions
- Sized to your upstand

Planning and building regulations for Chichester
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 Chichester 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.
