Planning and building regulations in Greater Manchester

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.

On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.

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 Greater Manchester: questions

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.

Can I have a manual opening vent?

Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.

Do I need planning permission for a roof lantern in Greater Manchester?

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.
