Planning and building regulations for Trowbridge
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 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.

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.

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 BA14.
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.
