Planning and building regulations for Horsham
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.
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 Horsham 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.
