Planning and building regulations for Greenwich
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.
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 Greenwich 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 Greenwich
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
Can I have a manual opening vent?
Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.
Can you fit a roof lantern in Greenwich?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Greenwich?
With the midsummer sun about 62.0° high at noon, roof glass in Greenwich gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
