Planning and building regulations for Trowbridge
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 Trowbridge 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 Trowbridge
Do aluminium lanterns get cold and drip?
Thermally broken frames are designed to reduce cold bridging. Condensation can still form if a room is very humid and poorly ventilated, which is why kitchens and bathrooms need extract ventilation.
Is aluminium recyclable?
Yes, aluminium can be recycled repeatedly. Ask your local waste site about the glass and seals, which are handled separately.
Can you fit a roof lantern in Trowbridge?
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.
Is it worth having solar-control glass in Trowbridge?
With the midsummer sun about 62.1° high at noon, roof glass in Trowbridge gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
