Planning and building regulations for Christchurch
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 Christchurch 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 Christchurch
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.
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.
Who checks building regulations for a lantern in Christchurch?
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.
Can you fit a roof lantern in Christchurch?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
