Planning and building regulations for Witham
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.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Witham 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 Witham
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.
Will I see a drawing before it is made?
For made-to-measure and special shapes, yes: the order is based on a drawing you approve, so the size you check is the size that gets made.
Who checks building regulations for a lantern in Witham?
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.
