Planning and building regulations for March
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in March 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 March
Does anthracite show dirt?
Less than white. Dust and pollen are more visible on dark gloss finishes, which is why most grey lanterns use a matt or textured finish.
Is anthracite grey the same as RAL 7016?
Yes. Some suppliers call it slate grey or charcoal grey, which can cause confusion, so always check the RAL number.
Who checks building regulations for a lantern in March?
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.
How quickly can I get a roof lantern in March?
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 PE15.
