Planning and building regulations for Hertford
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 in Hertford 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 Hertford
How long does replacement take on site?
For a like-for-like swap on a sound kerb, often a day. Kerb or roof repairs add time.

A modern double glazed lantern with a thermally broken frame loses far less heat than polycarbonate.
Do I need planning permission for a roof lantern in Hertford?
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.
