Flat rooflights for Cambridge homes

- Very low profile from outside
- Usually cheaper than a lantern

Planning and building regulations for Cambridge
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.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Cambridge 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 Cambridge
Are flat rooflights cheaper than lanterns?
Usually, size for size. They use one glass unit and a simple frame.
Do flat rooflights leak?
They should not, provided they are installed on a properly flashed upstand with the right fall and the seals are maintained.
Do you deliver roof lanterns to Cambridge?
Yes. Delivery to Cambridge (CB1) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Is it worth having solar-control glass in Cambridge?
With the midsummer sun about 61.2° high at noon, roof glass in Cambridge gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
