Planning and building regulations in Kent

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.

Aluminium roof lanterns in Kent: questions

Do aluminium lanterns get cold and drip?

Thermally broken frames are designed to reduce cold bridging. Condensation can still form if a room is very humid and poorly ventilated, which is why kitchens and bathrooms need extract ventilation.

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.

Is aluminium recyclable?

Yes, aluminium can be recycled repeatedly. Ask your local waste site about the glass and seals, which are handled separately.

Who checks building regulations for a lantern in Kent?

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.
