Planning and building regulations for Dereham
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 Dereham 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 Dereham
What is the difference between an orangery and a conservatory?
A conservatory has a mostly glazed roof; an orangery has a mostly solid roof with a lantern in the middle and usually more solid wall. Orangeries are easier to keep comfortable year round.
Should the lantern match my bifold doors?
A common choice is to match the outside colour, often anthracite. The inside can be white to keep the ceiling bright.
Is it worth having solar-control glass in Dereham?
With the midsummer sun about 60.8° high at noon, roof glass in Dereham gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Who checks building regulations for a lantern in Dereham?
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.
