I have also been told of a few glow worms recently in gardens in Brundall.
There are clearly more sites reported from Suffolk, but there could be many more in Norfolk that have not been reported. Disused railways lines are good hunting grounds, along with any areas that have been uncultivated for years. The underlying chalk geology of North Norfolk should in theory be suitable for glow worm colonies - Robin Scagell
