Planning and building regulations for Swanley
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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 Swanley 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 Swanley
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.
Can the coating be damaged?
Yes, by abrasive cleaning, some chemicals and silicone. Follow the care instructions supplied with your lantern.
How quickly can I get a roof lantern in Swanley?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for BR8.
Can you fit a roof lantern in Swanley?
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.
