Flat rooflights for Oxford homes
A single near-flat pane on an upstand: minimal, low and discreet.

- Sized to your upstand
- Minimal, frameless-looking from inside

Planning and building regulations for Oxford
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 Oxford 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 Oxford
Can a flat rooflight open?
Some ranges offer electric opening versions. Ask for availability for your size.
Can I walk on a flat rooflight?
Only if it is a walk-on rooflight designed for foot traffic. Standard rooflights are not designed to be walked on.
Who checks building regulations for a lantern in Oxford?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
Do I need planning permission for a roof lantern in Oxford?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
