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.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.

Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Hounslow
Can I have a manual opening vent?
Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.
What happens if it rains while the vent is open?
With a rain sensor the vent closes automatically. Without one it stays where you left it, so a sensor is worth having.
Can you fit a roof lantern in Hounslow?
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 Hounslow?
With the midsummer sun about 62.0° high at noon, roof glass in Hounslow gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
