Replacement roof lanterns for Ely homes
Swap a tired, leaking or polycarbonate lantern for modern double glazing.
In midsummer the noon sun stands about 61.0° high over Ely, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Reuse the kerb if sound and to size
- Replace old polycarbonate with glass
- Warmer, quieter, brighter

Planning and building regulations for Ely
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 Ely 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 Ely
Can I replace polycarbonate panels with glass?
Usually not in the old frame: glass is much heavier than polycarbonate and the frame was not designed for it. Replacing the whole lantern is the safer route.
How long does replacement take on site?
For a like-for-like swap on a sound kerb, often a day. Kerb or roof repairs add time.
Do you deliver roof lanterns to Ely?
Yes. Delivery to Ely (CB7) 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 Ely?
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.
