Planning and building regulations for Carshalton
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 Carshalton 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 Carshalton
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.
Can I have cresting without finials, or the other way round?
Usually yes. Ranges treat cresting and finials as options. Tell us what you want and the quote will list each item.
Do I need planning permission for a roof lantern in Carshalton?
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.
Can you fit a roof lantern in Carshalton?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
