Buying a roof lantern in Cornwall
We price lanterns for Cornwall homes from the outside size of the kerb, check your measurements before ordering and confirm everything in writing first.
Daylight here ranges from about 8h 01m on the shortest day to 16h 26m in midsummer, so glass choice matters: self-cleaning glass for hard-to-reach roofs and solar control for big or south-facing lanterns.

Planning and building regulations in Cornwall
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 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.

Roof lanterns in Cornwall: questions
Can you fit a roof lantern in Cornwall?
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 Cornwall?
With the midsummer sun about 63.1° high at noon, roof glass in Cornwall gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do you deliver roof lanterns to Cornwall?
Yes. Delivery to Cornwall (Cornwall) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Can I order online and pay by card on the website?
Not yet. Every lantern is checked against your measurements before it is ordered, so orders are placed from a written quote. The quote explains how and when to pay.
