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 black get hotter?
The frame surface does, but the effect on the room is small next to the choice of glass.
Is a black lantern too dark inside?
The frame is a small part of what you see; the glass dominates. Black frames inside create a graphic grid that many people like. If you want a softer look, choose white inside.
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.
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.
