Planning and building regulations for Streatham
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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Streatham 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 Streatham
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.
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.
