Planning and building regulations for Northolt
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 Northolt 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 Northolt
Can a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
Do I need planning permission for a roof lantern in Northolt?
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.
Who checks building regulations for a lantern in Northolt?
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.
