Planning and building regulations for Grantham
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 Grantham 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 Grantham
Does it help in winter?
Solar control mainly limits summer heat. Winter heat loss is governed by the U-value, which depends on the glazing unit and frame.
Will solar-control glass make the room dark?
It lets slightly less light through than clear glass, but a roof lantern admits so much daylight that most people do not notice the difference.
How quickly can I get a roof lantern in Grantham?
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 NG31.
Who checks building regulations for a lantern in Grantham?
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.
