Planning and building regulations for Corsham
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.
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 Corsham 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 Corsham
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 anthracite grey the same as RAL 7016?
Yes. Some suppliers call it slate grey or charcoal grey, which can cause confusion, so always check the RAL number.
Is it worth having solar-control glass in Corsham?
With the midsummer sun about 62.0° high at noon, roof glass in Corsham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do you deliver roof lanterns to Corsham?
Yes. Delivery to Corsham (SN13) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
