Planning and building regulations for Finchley
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 Finchley 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 Finchley
Can I add a lantern to my existing orangery roof?
If the roof has a suitable opening and upstand, yes. If not, the roof needs structural alteration first, which is a job for a builder with an engineer's input.
What is the difference between an orangery and a conservatory?
A conservatory has a mostly glazed roof; an orangery has a mostly solid roof with a lantern in the middle and usually more solid wall. Orangeries are easier to keep comfortable year round.
Is it worth having solar-control glass in Finchley?
With the midsummer sun about 61.8° high at noon, roof glass in Finchley gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
How quickly can I get a roof lantern in Finchley?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for N3.
