Replacement roof lanterns for Northwich homes
Swap a tired, leaking or polycarbonate lantern for modern double glazing.
In midsummer the noon sun stands about 60.2° high over Northwich, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Replace old polycarbonate with glass
- Supply only or a fitting quote
- Reuse the kerb if sound and to size

Planning and building regulations for Northwich
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 Northwich 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.
