Planning and building regulations for Darwen
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 Darwen 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 Darwen
Can I have white inside and anthracite outside?
Yes, that is one of the most common combinations.
Does a white lantern show dirt?
Outside, white shows dirt more than grey. Self-cleaning glass helps with the glass, and the frames benefit from an occasional wash.
Is it worth having solar-control glass in Darwen?
With the midsummer sun about 59.7° high at noon, roof glass in Darwen gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Can you fit a roof lantern in Darwen?
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.
