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
Do you need to survey before fitting?
For a lantern on a ready upstand, clear photos and measurements are often enough. Replacements and new openings need a survey.
Can you build the upstand as well?
We can quote for upstands and associated roofing on a survey basis.
Is it worth having solar-control glass in Swanley?
With the midsummer sun about 62.0° high at noon, roof glass in Swanley gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
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.
