Planning and building regulations in County Durham
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 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.

Opening roof lanterns in County Durham: questions
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
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 a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
Who checks building regulations for a lantern in County Durham?
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.
