Planning and building regulations for London
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.
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 in London 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 London
What is the smallest roof lantern?
Many ranges start at around 800–1000 mm. Below that, a flat rooflight is usually the better product.
Does a small lantern need an opening vent?
Not usually. Background ventilation for the room can come from trickle vents or extract fans. Vents are more useful on lanterns over kitchens and large living spaces.
Is it worth having solar-control glass in London?
With the midsummer sun about 61.9° high at noon, roof glass in London gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do you deliver roof lanterns to London?
Yes. Delivery to London (EC1A) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
