Planning and building regulations for Islington
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 Islington 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 Islington
Are flat rooflights cheaper than lanterns?
Usually, size for size. They use one glass unit and a simple frame.

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 Islington?
Yes. Delivery to Islington (N1) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Do I need planning permission for a roof lantern in Islington?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
