Planning and building regulations in Cornwall
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.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations 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.

Black roof lanterns in Cornwall: questions
What black is it?
Usually RAL 9005. If your doors are a different black, such as RAL 9004 or 9011, give us the code.
Does black get hotter?
The frame surface does, but the effect on the room is small next to the choice of glass.
Will black fade?
Quality powder coatings are designed for UK weather. Matt finishes may show a slight sheen change over many years.
Do I need planning permission for a roof lantern in Cornwall?
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.
