Planning and building regulations for Carshalton
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 Carshalton 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 Carshalton
Can the inside be a different grey?
Yes. Any combination is possible on most aluminium ranges; non-stock colours carry a small surcharge.
Does anthracite show dirt?
Less than white. Dust and pollen are more visible on dark gloss finishes, which is why most grey lanterns use a matt or textured finish.

Is it worth having solar-control glass in Carshalton?
With the midsummer sun about 62.1° high at noon, roof glass in Carshalton gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
