Sorry, you don't know much about UK mains distribution do you ?.

The neutral wire in the UK is connected to ground only at the sub station
under normal situations and nowhere else. Therefore it can be at a
different potential to true ground.

Actually, in a TN-C-S supply, which is pretty common nowadays, they are
connected together in the service head (grey box with big fuse in it
belonging to the electricity co. next to the customers' meter).
