I agree, I can't see any PME label. and earthing via the water service is not recommended unless the water supply has been set aside for such purpose. I would get the customer to contact the supplier to get a contact number for the local DNO.

You/the home owner need to talk to the supplier. Be prepared to put a stake in as you may find this may the "easiest" way to approach the issue. Obviously you need to put bonding in place and then a nice new board. Given you only have 3 circuits I'd be recommending a RCBO unit.

Hope this helps.

You should have and hopefully have put an earth rod in the ground and supplied it with an earth.

As you say it is labelled as a PME supply, if I were you I'd phone the DNO on behalf of the customer to make sure it get done.

Goes to show how thick or rushed the meter fitter is, to notice no earth on a labelled PME supply, get on the phone and say it appears the meter fitted seems to have removed the earth (a lie, but it might get them out even quicker).
