Planning and building regulations for Sevenoaks
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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Sevenoaks 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 Sevenoaks
Is white cheaper?
White is a stock colour, so it costs the same as the other stock colours.
Which white matches uPVC windows?
Gloss white, often RAL 9016, is usually closest. Send us a photo of your windows if you are unsure.
Do I need planning permission for a roof lantern in Sevenoaks?
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.
Is it worth having solar-control glass in Sevenoaks?
With the midsummer sun about 62.2° high at noon, roof glass in Sevenoaks gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
