Planning and building regulations for Portsmouth
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 Portsmouth 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.
