Planning and building regulations for Calne
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.
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 Calne 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 Calne
Can I get a grey uPVC lantern?
Some ranges offer foiled colours. The choice is narrower than aluminium.
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 it worth having solar-control glass in Calne?
With the midsummer sun about 62.0° high at noon, roof glass in Calne gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Can you fit a roof lantern in Calne?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
