Why are you running the earth through the wall anyway?

Doesn't the earth connection have to be to the metal of the pipe that
emerges from the ground ie before any joints/meters etc...

Or does that vary depending on the stype of electricity supply and
this connection just being an equipotential bond (better consumer
side of the meter) or part of the safety earth bonding (better supply
side)?

On (metal) pipework within 600mm of the meter on the consumers side of
the meter but before any branches or tees OR within 600mm of the point
of entry to the building if the meter is external. Having the bond
visible at the meter cabinet saves silly bits of card being left by
Transco fitters saying bonding should be investigated if they do a
meter change or other work.

Quite often gas companies put insulators in their meters to stop currents
passing down their metal pipes.
