Planning and building regulations for Weymouth

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.

Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.

Building regulations in Weymouth 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.

Roof lantern questions from Weymouth

Is it worth having solar-control glass in Weymouth?

With the midsummer sun about 62.8° high at noon, roof glass in Weymouth gets strong summer sun. Solar control is recommended for large or south-facing lanterns.

Who checks building regulations for a lantern in Weymouth?

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.

Do I need planning permission for a roof lantern in Weymouth?

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.
