Planning and building regulations for Wellingborough
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 Wellingborough 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 Wellingborough
How long does replacement take on site?
For a like-for-like swap on a sound kerb, often a day. Kerb or roof repairs add time.
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.
Do you deliver roof lanterns to Wellingborough?
Yes. Delivery to Wellingborough (NN8) 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 Wellingborough?
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.
