Planning and building regulations for Whitehaven
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 Whitehaven 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 Whitehaven
Which way should the ridge run?
The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.
Can a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
How quickly can I get a roof lantern in Whitehaven?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for CA28.
Who checks building regulations for a lantern in Whitehaven?
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.
