Planning and building regulations for Sandown
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.
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 Sandown 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 Sandown
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 a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
Is it worth having solar-control glass in Sandown?
With the midsummer sun about 62.8° high at noon, roof glass in Sandown gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Who checks building regulations for a lantern in Sandown?
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.
