Planning and building regulations for Hertford
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 Hertford 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 Hertford
Is a pyramid lantern more expensive than a rectangular one?
Per square metre it can cost slightly more, because every pane is a triangle and the apex needs a special joint. The difference is usually small next to the effect of size and glass choice.
What is the largest square lantern?
Ranges differ. Many go to around 3 m square, with extra hip bars on larger sizes. Tell us your kerb size and we will confirm which ranges can make it.
Do I need planning permission for a roof lantern in Hertford?
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.
Can you fit a roof lantern in Hertford?
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.
