Planning and building regulations for King's Lynn
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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 King's Lynn 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 King's Lynn
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.
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.
Who checks building regulations for a lantern in King's Lynn?
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.
Is it worth having solar-control glass in King's Lynn?
With the midsummer sun about 60.7° high at noon, roof glass in King's Lynn gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
