Planning and building regulations for Wymondham
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.
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 Wymondham 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 Wymondham
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.
Can a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
Do you deliver roof lanterns to Wymondham?
Yes. Delivery to Wymondham (NR18) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Do I need planning permission for a roof lantern in Wymondham?
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.
