There was an ancient (1950s) steel pipe bringing mains water into my
house under the front room and then up in the cup'd under the stairs.
There there was a stop cock and it went into copper pipe and onto the
copper a large sleeved earth wire was connected with a tag on saying "Do
Not Remove".

The steel pipe was leaking so I have taken it all out and replaced with
blue plastic pipe. Was looking at the earth arrangement and wondering if
I need to earth the wiring in another way, into the ground or something,
or are we still earthed through the water in the plastic pipe out to the
outside world?

It was common many many years ago to provide the earth via the water pipe.
Not so today. Get your leccy board in to sort it out.

It's nothing to do with the leccy board.



Meanwhile what might help Tim is to know that the relevant function of
"Electricity Boards" was transferred as part of the privatisation of the
industry to distribution network operators (DNOs). As John has already
pointed out they can and do deal with earthing - although they may
charge (and will require main bonding to be up to current requirements
before they supply PME).
