Planning and building regulations for Blackburn
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 Blackburn 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 Blackburn
How accurate do my measurements need to be?
Accurate to the millimetre on the outside of the kerb, measured at several points. Kerbs are rarely perfectly square, so measure both diagonals too. Our measuring guide shows how.
Will I see a drawing before it is made?
For made-to-measure and special shapes, yes: the order is based on a drawing you approve, so the size you check is the size that gets made.
How quickly can I get a roof lantern in Blackburn?
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 BB1.
Do you deliver roof lanterns to Blackburn?
Yes. Delivery to Blackburn (BB1) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
