Planning and building regulations in Cornwall
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.
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 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.

Aluminium roof lanterns in Cornwall: questions
Is aluminium recyclable?
Yes, aluminium can be recycled repeatedly. Ask your local waste site about the glass and seals, which are handled separately.
Will the colour fade?
Polyester powder coatings are designed for outdoor use and hold their colour well. Coastal sites benefit from occasional washing to remove salt deposits.
Can I paint an aluminium lantern later?
It can be repainted with suitable systems, but it is far better to choose the right powder-coated colour at the start.
Who checks building regulations for a lantern in Cornwall?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
