Planning and building regulations for Braintree
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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Braintree 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 Braintree
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.
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.
Who checks building regulations for a lantern in Braintree?
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.
How quickly can I get a roof lantern in Braintree?
