Planning and building regulations for Cheshunt
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 Cheshunt 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 Cheshunt
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.
How is a large lantern delivered?
On pallets, usually with the frame and glass packed separately. The heaviest single item is normally a glass unit, which needs two or more people to lift safely.
How quickly can I get a roof lantern in Cheshunt?
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 EN8.
Is it worth having solar-control glass in Cheshunt?
With the midsummer sun about 61.7° high at noon, roof glass in Cheshunt gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
