Planning and building regulations for Boston
In England, building regulations energy guidance sets a limiting U-value of 2.2 W/m²K for new and replacement rooflights in existing homes, measured horizontally.
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 Boston 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 Boston
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.
Can the inside be a different grey?
Yes. Any combination is possible on most aluminium ranges; non-stock colours carry a small surcharge.
Is it worth having solar-control glass in Boston?
With the midsummer sun about 60.5° high at noon, roof glass in Boston gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Can you fit a roof lantern in Boston?
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.
