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.
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 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
What black is it?
Usually RAL 9005. If your doors are a different black, such as RAL 9004 or 9011, give us the code.
Is a black lantern too dark inside?
The frame is a small part of what you see; the glass dominates. Black frames inside create a graphic grid that many people like. If you want a softer look, choose white inside.
Is it worth having solar-control glass in Penzance?
With the midsummer sun about 63.3° high at noon, roof glass in Penzance gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
