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
Can I have a manual opening vent?
Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.
Can a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
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.
Can you fit a roof lantern in Corsham?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
