Planning and building regulations for Seaham
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 Seaham 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 Seaham
Will white uPVC yellow over time?
Modern uPVC profiles are UV-stabilised and should stay white with normal cleaning. Very old lanterns, especially with polycarbonate panels, are the ones that discolour.
Are uPVC lanterns as good as aluminium?
They do the same job at a lower price, with bulkier frames and fewer colour and size options. For most showpiece extensions aluminium is worth the extra.
How quickly can I get a roof lantern in Seaham?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for SR7.
Do you deliver roof lanterns to Seaham?
Yes. Delivery to Seaham (SR7) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
