Planning and building regulations in Wiltshire
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.

Roof lantern upstands in Wiltshire: questions
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
Can I order a lantern before the upstand is built?
Yes, if you build the upstand to the lantern's stated external size. Many people order the lantern and upstand together so they match.
Who makes the upstand weatherproof?
Your roofer, by dressing the roof membrane up the outside of the upstand. The lantern then sits over it.
Do I need planning permission for a roof lantern in Wiltshire?
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.
