Planning and building regulations for Welwyn Garden City
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Welwyn Garden City 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 Welwyn Garden City
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.
Will black fade?
Quality powder coatings are designed for UK weather. Matt finishes may show a slight sheen change over many years.
