Planning and building regulations in Lancashire
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 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.

Opening roof lanterns in Lancashire: questions
Can a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
Can I have a manual opening vent?
Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
Who checks building regulations for a lantern in Lancashire?
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.
