Planning and building regulations for Berkhamsted
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 Berkhamsted 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 Berkhamsted
Do I still need to clean self-cleaning glass?
Occasionally. It keeps the glass cleaner for longer, but heavy dirt and droppings still need a gentle rinse, especially in dry spells.
Does it work under trees?
Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.
Do you deliver roof lanterns to Berkhamsted?
Yes. Delivery to Berkhamsted (HP4) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Who checks building regulations for a lantern in Berkhamsted?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
