Planning and building regulations for Chelsea
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 Chelsea 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 Chelsea
Is a contemporary lantern the same as a flat rooflight?
No. A contemporary lantern still has sloping glass and a ridge or apex; it simply has slimmer frames and fewer bars. A flat rooflight is a single, nearly flat pane of glass on an upstand.
Can I have a contemporary lantern in white?
Yes, though most buyers choose grey or black because the slimmer frame is the point and dark frames disappear against the sky.
Is it worth having solar-control glass in Chelsea?
With the midsummer sun about 62.0° high at noon, roof glass in Chelsea gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do you deliver roof lanterns to Chelsea?
Yes. Delivery to Chelsea (SW10) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
