Planning and building regulations for Washington
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 Washington 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 Washington
Can the inside be a different grey?
Yes. Any combination is possible on most aluminium ranges; non-stock colours carry a small surcharge.
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.
Is it worth having solar-control glass in Washington?
With the midsummer sun about 58.5° high at noon, roof glass in Washington gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
How quickly can I get a roof lantern in Washington?
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 NE37.
