Planning and building regulations for Portslade
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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 Portslade 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 Portslade
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.
Will a new lantern be warmer?
A modern double glazed lantern with a thermally broken frame loses far less heat than polycarbonate.
Can you fit a roof lantern in Portslade?
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.
Do I need planning permission for a roof lantern in Portslade?
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.
