Planning and building regulations for Surbiton
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 Surbiton 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 Surbiton
Can I order a lantern before the upstand is built?
Yes, if you build the upstand to the lantern's stated external size. Many people order the lantern and upstand together so they match.
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
Who checks building regulations for a lantern in Surbiton?
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.
Can you fit a roof lantern in Surbiton?
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.
