Planning and building regulations for London
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in London 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.
