Planning and building regulations for Enfield
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.
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 in Enfield 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 Enfield
Can I have a manual opening vent?
Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.
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.
Who checks building regulations for a lantern in Enfield?
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.
Do I need planning permission for a roof lantern in Enfield?
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.
