Planning and building regulations for Chelmsford
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 Chelmsford 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 Chelmsford
Is white cheaper?
White is a stock colour, so it costs the same as the other stock colours.
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.
Do I need planning permission for a roof lantern in Chelmsford?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
Is it worth having solar-control glass in Chelmsford?
With the midsummer sun about 61.7° high at noon, roof glass in Chelmsford gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
