Planning and building regulations for Carlisle
In England, building regulations energy guidance sets a limiting U-value of 2.2 W/m²K for new and replacement rooflights in existing homes, measured horizontally.
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 Carlisle 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 Carlisle
Do bespoke lanterns cost much more?
For simple rectangles the premium over a stock size is usually modest. Special shapes cost more because each one is engineered individually.
How accurate do my measurements need to be?
Accurate to the millimetre on the outside of the kerb, measured at several points. Kerbs are rarely perfectly square, so measure both diagonals too. Our measuring guide shows how.
Who checks building regulations for a lantern in Carlisle?
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.
