Planning and building regulations for Coulsdon
For homes in England, a new or replacement rooflight should achieve a U-value of 2.2 W/m²K or better in the horizontal position, under Approved Document L.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Coulsdon 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.

How is a large lantern delivered?
On pallets, usually with the frame and glass packed separately. The heaviest single item is normally a glass unit, which needs two or more people to lift safely.
Does a large lantern need structural calculations?
The roof structure around it usually does. Your engineer or building control body will want the lantern's weight and the opening size.
Do you deliver roof lanterns to Coulsdon?
Yes. Delivery to Coulsdon (CR5) 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 Coulsdon?
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.
