Three panes for lower heat loss, a warmer inner surface and less noise.

Planning and building regulations for Bath
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 Bath 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 Bath
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.
Can I have triple glazing with solar control?
Yes. Triple units usually include a solar-control or neutral coating.
Do you deliver roof lanterns to Bath?
Yes. Delivery to Bath (BA1) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Do I need planning permission for a roof lantern in Bath?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
