Is the ESQCR flawed by requiring that the NE link is at the supply cut-out?  Unless I'm much mistaken, in the USA, the link is in the consumer unit instead.


Moving the NE link to the consumer's side allows something like a VOELCB or over-voltage trip to totally isolate the house from the incoming supply.  If we then require insulating sections in any supply pipes (gas, water, etc.) that aren't already plastic, then it should be possible to totally isolate the house from the supply in the event of a broken PEN.  I can't think of any likely situations where any other random extraneous conductive parts within the curtilage of the house are likely to end up connected to the public supply.
