Planning and building regulations for Hatfield
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 Hatfield 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 Hatfield
Do I need triple glazing to meet building regulations?
Not usually. Well-specified double glazed lanterns generally meet the limiting values for rooflights. Triple glazing is an upgrade, not normally a requirement. Your building control body can confirm for your project.
Can I have triple glazing with solar control?
Yes. Triple units usually include a solar-control or neutral coating.
How quickly can I get a roof lantern in Hatfield?
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 AL10.
Is it worth having solar-control glass in Hatfield?
With the midsummer sun about 61.7° high at noon, roof glass in Hatfield gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
