I'm guessing it originates outside this property, as the current was there with the main switch off.Assuming both Main protective Bonding connections are in place, and your confirmation that Ze is good, I cant see there is a lot you can do.
Its always possible its originating from a neighbouring property with a fault maybe?
I watch this thread with interest.
Maybe I should recommend the customer gets in touch with the DNO.
