Planning and building regulations for Penzance
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 Penzance 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 Penzance
Do you need to survey before fitting?
For a lantern on a ready upstand, clear photos and measurements are often enough. Replacements and new openings need a survey.
Can you build the upstand as well?
We can quote for upstands and associated roofing on a survey basis.
Do I need planning permission for a roof lantern in Penzance?
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 Penzance?
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.
