Planning and building regulations for Windsor
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 Windsor 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 Windsor
What happens if it rains while the vent is open?
With a rain sensor the vent closes automatically. Without one it stays where you left it, so a sensor is worth having.
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
Is it worth having solar-control glass in Windsor?
With the midsummer sun about 62.0° high at noon, roof glass in Windsor gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in Windsor?
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.
