Planning and building regulations for Barnet
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 Barnet 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 Barnet
Is aluminium recyclable?
Yes, aluminium can be recycled repeatedly. Ask your local waste site about the glass and seals, which are handled separately.
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 Barnet?
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.
Is it worth having solar-control glass in Barnet?
With the midsummer sun about 61.8° high at noon, roof glass in Barnet gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
