Planning and building regulations for Truro
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 Truro 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 Truro
Are flat rooflights cheaper than lanterns?
Usually, size for size. They use one glass unit and a simple frame.
Can I walk on a flat rooflight?
Only if it is a walk-on rooflight designed for foot traffic. Standard rooflights are not designed to be walked on.
Do I need planning permission for a roof lantern in Truro?
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.
Can you fit a roof lantern in Truro?
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.
