Planning and building regulations for Bolton
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 Bolton 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 Bolton
How is a large lantern delivered?
On pallets, usually with the frame and glass packed separately. The heaviest single item is normally a glass unit, which needs two or more people to lift safely.
Does a large lantern need structural calculations?
The roof structure around it usually does. Your engineer or building control body will want the lantern's weight and the opening size.
Who checks building regulations for a lantern in Bolton?
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.
Can you fit a roof lantern in Bolton?
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.
