Choosing flat rooflights in Lincolnshire
A single near-flat pane on an upstand: minimal, low and discreet.
Across Lincolnshire, the shortest day brings around 7h 32m of daylight and the midsummer sun reaches about 60.3° at noon. A lantern collects light from the bright overhead sky all year, and the right glass keeps the long summer days comfortable.
- Sized to your upstand
- Single glazed unit with a slight fall
- Usually cheaper than a lantern
- Fixed or electric opening versions

Planning and building regulations in Lincolnshire
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 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.
