Planning and building regulations for Bodmin
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 in Bodmin 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 Bodmin
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.
Do I need planning permission for a roof lantern in Bodmin?
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.
Do you deliver roof lanterns to Bodmin?
Yes. Delivery to Bodmin (PL31) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
