Planning and building regulations for Dartford
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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 Dartford 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 Dartford
Does a small lantern need an opening vent?
Not usually. Background ventilation for the room can come from trickle vents or extract fans. Vents are more useful on lanterns over kitchens and large living spaces.
Can I fit a small lantern myself?
Small lanterns are within the reach of a competent builder or roofer. The critical parts are a level, square, weatherproof upstand and the manufacturer's fixing instructions. In existing homes, replacement rooflights are building work that may need building control involvement.
Do I need planning permission for a roof lantern in Dartford?
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.
Who checks building regulations for a lantern in Dartford?
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.
