Planning and building regulations for Daventry
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 Daventry 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 Daventry
Who makes the upstand weatherproof?
Your roofer, by dressing the roof membrane up the outside of the upstand. The lantern then sits over it.
What height should my upstand be?
High enough to keep water away from the lantern seal, commonly at least 150 mm above the finished roof surface. Follow the instructions for your chosen range.
Do you deliver roof lanterns to Daventry?
Yes. Delivery to Daventry (NN11) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Who checks building regulations for a lantern in Daventry?
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.
