1. He could not see that the electricity consumer unit was earthed to the
pipe from the gas meter. I know the earth connection is there but it is on
the other side of the wall, behind plasterboard.

Thanks, Chris


Its called bonding and the gas supply pipe directly after the meter is
bonded to the consumer earth point, not the other way around. I believe it
is requirment that the connection is visible and marked as a safety earth.
