Planning and building regulations for Caterham
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 Caterham 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 Caterham
Do flat rooflights leak?
They should not, provided they are installed on a properly flashed upstand with the right fall and the seals are maintained.
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 you deliver roof lanterns to Caterham?
Yes. Delivery to Caterham (CR3) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Who checks building regulations for a lantern in Caterham?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
