Planning and building regulations in Dorset
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 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.

Contemporary roof lanterns in Dorset: questions
Is a contemporary lantern the same as a flat rooflight?
No. A contemporary lantern still has sloping glass and a ridge or apex; it simply has slimmer frames and fewer bars. A flat rooflight is a single, nearly flat pane of glass on an upstand.
Are contemporary lanterns weaker?
They are engineered for the sizes they are sold in. That is exactly why their maximum sizes are often smaller: the frame is slimmer, so each range has its own limits.
Do contemporary lanterns cost more?
Usually a little more per size than a standard range, because the bigger glass units cost more to make and handle.
Do I need planning permission for a roof lantern in Dorset?
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.
