Planning and building regulations for Watford
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.
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 Watford 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 Watford
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.

Who checks building regulations for a lantern in Watford?
