Planning and building regulations for Putney
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 Putney 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 Putney
Is triple glazing heavier to lift?
Yes, the glass is roughly 45% heavier. Plan for extra hands or lifting equipment on larger lanterns.
Do I need triple glazing to meet building regulations?
Not usually. Well-specified double glazed lanterns generally meet the limiting values for rooflights. Triple glazing is an upgrade, not normally a requirement. Your building control body can confirm for your project.
Who checks building regulations for a lantern in Putney?
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.
Is it worth having solar-control glass in Putney?
With the midsummer sun about 62.0° high at noon, roof glass in Putney gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
