Planning and building regulations in the Isle of Wight
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.
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 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.

Opening roof lanterns in the Isle of Wight: questions
Can a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
What happens if it rains while the vent is open?
With a rain sensor the vent closes automatically. Without one it stays where you left it, so a sensor is worth having.
Can I have a manual opening vent?
Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.
Who checks building regulations for a lantern in the Isle of Wight?
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.
