Planning and building regulations for Swanley
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 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 help in winter?
Solar control mainly limits summer heat. Winter heat loss is governed by the U-value, which depends on the glazing unit and frame.
Is solar control the same as tinted glass?
Solar-control coatings often look slightly tinted, but the performance comes from the coating, not just the colour.
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.
Do I need planning permission for a roof lantern in Swanley?
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.
