Planning and building regulations for London
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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in London 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 London
Will a traditional lantern need planning permission?
The style does not change the planning position; size, height and location do. Listed buildings and conservation areas are the main cases where consent is more likely to be needed.
Do you make timber traditional lanterns?
Our range is aluminium and uPVC. Aluminium can be powder-coated in heritage colours that suit timber windows and doors.
Do you deliver roof lanterns to London?
Yes. Delivery to London (EC1A) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Is it worth having solar-control glass in London?
With the midsummer sun about 61.9° high at noon, roof glass in London gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
