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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
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.

Yes, to mainland Britain addresses, with Northern Ireland, the Highlands and islands by arrangement. Tell us about access, parking restrictions and whether a forklift or tail lift will be needed.
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.
