Planning and building regulations for Windsor
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 Windsor 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 Windsor
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.
Is uPVC heavier?
Weight is dominated by the glass, so the difference is small.
Who checks building regulations for a lantern in Windsor?
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.
