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.
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 a white lantern show dirt?
Outside, white shows dirt more than grey. Self-cleaning glass helps with the glass, and the frames benefit from an occasional wash.
Is white cheaper?
White is a stock colour, so it costs the same as the other stock colours.
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.
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.
