Planning and building regulations for Purley
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 Purley 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 Purley
What is the largest square lantern?
Ranges differ. Many go to around 3 m square, with extra hip bars on larger sizes. Tell us your kerb size and we will confirm which ranges can make it.
Is a pyramid lantern more expensive than a rectangular one?
Per square metre it can cost slightly more, because every pane is a triangle and the apex needs a special joint. The difference is usually small next to the effect of size and glass choice.
Can you fit a roof lantern in Purley?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Purley?
With the midsummer sun about 62.1° high at noon, roof glass in Purley gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
