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)?
