Planning and building regulations for Beckenham
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
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 Beckenham 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 Beckenham
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.
Is triple glazing heavier to lift?
Yes, the glass is roughly 45% heavier. Plan for extra hands or lifting equipment on larger lanterns.
Is it worth having solar-control glass in Beckenham?
With the midsummer sun about 62.0° high at noon, roof glass in Beckenham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do you deliver roof lanterns to Beckenham?
Yes. Delivery to Beckenham (BR3) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
