Planning and building regulations in Cornwall

In England, building regulations energy guidance sets a limiting U-value of 2.2 W/m²K for new and replacement rooflights in existing homes, measured horizontally.

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 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.

uPVC roof lanterns in Cornwall: questions

Can I get a grey uPVC lantern?

Some ranges offer foiled colours. The choice is narrower than aluminium.

Are uPVC lanterns as good as aluminium?

They do the same job at a lower price, with bulkier frames and fewer colour and size options. For most showpiece extensions aluminium is worth the extra.

Is uPVC heavier?

Weight is dominated by the glass, so the difference is small.

Do I need planning permission for a roof lantern in Cornwall?

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.
