Planning and building regulations in Dorset
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 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.

White roof lanterns in Dorset: questions
Is white cheaper?
White is a stock colour, so it costs the same as the other stock colours.
Which white matches uPVC windows?
Gloss white, often RAL 9016, is usually closest. Send us a photo of your windows if you are unsure.
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.
How quickly can I get a roof lantern in Dorset?
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 Dorset.
