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.
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.

Questions from Canterbury
Can I have an opening vent in a pyramid lantern?
Some ranges can fit a vent in one of the triangular panes, others cannot. We will tell you on the quote whether your chosen range allows it.
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 it worth having solar-control glass in Canterbury?
With the midsummer sun about 62.2° high at noon, roof glass in Canterbury gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
