Planning and building regulations for Mitcham
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.
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 Mitcham 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 Mitcham
Will a square lantern leak at the top?
It should not when it is correctly installed and maintained. The apex is factory-designed to shed water; leaks usually come from the upstand or roof membrane rather than the lantern itself, which is why the upstand detail matters.
Is a pyramid lantern more expensive than a rectangular one?
Per square metre it can cost slightly more, because every pane is a triangle and the apex needs a special joint. The difference is usually small next to the effect of size and glass choice.
Who checks building regulations for a lantern in Mitcham?
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 Mitcham?
With the midsummer sun about 62.0° high at noon, roof glass in Mitcham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
