Planning and building regulations for Stevenage
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 Stevenage 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 Stevenage
Can I collect?
Ask us when you request your quote. Collection depends on where your lantern is made.
What if the lantern arrives damaged?
Check the packaging and glass on delivery where you can, note any damage on the delivery paperwork and tell us straight away with photos. Goods remain our responsibility until they are delivered to you.
Do I need planning permission for a roof lantern in Stevenage?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
Is it worth having solar-control glass in Stevenage?
With the midsummer sun about 61.5° high at noon, roof glass in Stevenage gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
