Planning and building regulations for Formby
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 Formby 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 Formby
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.
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.

We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
How quickly can I get a roof lantern in Formby?
