Planning and building regulations for Holloway
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 Holloway 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 Holloway
What is the biggest roof lantern you can supply?
It depends on the range. Some go to about 6 m by 4 m with intermediate rafters. Send us your kerb size and we will confirm what can be made.
Do large lanterns overheat a room?
A large area of south-facing glass can make a room warm on sunny days. Solar-control glass, an opening vent and good background ventilation all help. Our guide on overheating explains the options.
Do I need planning permission for a roof lantern in Holloway?
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 Holloway?
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.
