Planning and building regulations for Nelson
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 in Nelson 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 Nelson
Does a large lantern need structural calculations?
The roof structure around it usually does. Your engineer or building control body will want the lantern's weight and the opening size.
What is the biggest roof lantern you can supply?
It depends on the range. Some go to about 6 m by 4 m with intermediate rafters. Send us your kerb size and we will confirm what can be made.
Can you fit a roof lantern in Nelson?
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.
Is it worth having solar-control glass in Nelson?
With the midsummer sun about 59.6° high at noon, roof glass in Nelson gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
