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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
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 have triple glazing with solar control?
Yes. Triple units usually include a solar-control or neutral coating.
Do I need triple glazing to meet building regulations?
Not usually. Well-specified double glazed lanterns generally meet the limiting values for rooflights. Triple glazing is an upgrade, not normally a requirement. Your building control body can confirm for your project.
How quickly can I get a roof lantern in Calne?
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 SN11.
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.
