Planning and building regulations for Sevenoaks
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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Sevenoaks 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 Sevenoaks
Can I have a contemporary lantern in white?
Yes, though most buyers choose grey or black because the slimmer frame is the point and dark frames disappear against the sky.
Do contemporary lanterns cost more?
Usually a little more per size than a standard range, because the bigger glass units cost more to make and handle.
Can you fit a roof lantern in Sevenoaks?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Who checks building regulations for a lantern in Sevenoaks?
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.
