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.
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 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 the coating be damaged?
Yes, by abrasive cleaning, some chemicals and silicone. Follow the care instructions supplied with your lantern.
Does it work under trees?
Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.
Do you deliver roof lanterns to Sevenoaks?
Yes. Delivery to Sevenoaks (TN13) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
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.
