Planning and building regulations for Derby
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 Derby 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 Derby
What height should my upstand be?
High enough to keep water away from the lantern seal, commonly at least 150 mm above the finished roof surface. Follow the instructions for your chosen range.
Who makes the upstand weatherproof?
Your roofer, by dressing the roof membrane up the outside of the upstand. The lantern then sits over it.
Do you deliver roof lanterns to Derby?
Yes. Delivery to Derby (DE1) is quoted for your exact postcode and confirmed in writing on your quote, together with the lead time.
Do I need planning permission for a roof lantern in Derby?
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.
