Planning and building regulations for Dunstable
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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
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.
Is it worth having solar-control glass in Dunstable?
With the midsummer sun about 61.6° high at noon, roof glass in Dunstable gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
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.
