Planning and building regulations in Hertfordshire
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.
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 Hertfordshire: 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.
Do I need planning permission for a roof lantern in Hertfordshire?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
