Planning and building regulations for Dunstable
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Dunstable 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 Dunstable
My old lantern leaks. Is it the lantern or the roof?
Often the roof or kerb detailing. A survey or close inspection will tell. If the lantern is the problem, replacing it is usually better value than repairing old polycarbonate.
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
Do you deliver roof lanterns to Dunstable?
Yes. Delivery to Dunstable (LU6) 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 Dunstable?
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.
