I have recently replaced approx 3m of lead water main to the house with
25mm MDPE.

At the weekend I made the final coonection inside the house, and
removed the lead tail and stopcock that previously served the house.
When doing so I noticed an electrical wire attached to the lead pipe,
and assume this has something to do with the earth for the electrics
meter cupboard.

Do I need to provide anothe connection to earth. Should I extend the
(now severed) wire back to the water board's supply, which is still in
lead?

I think my gas has been sleeved in the last 18 months, so has that
removed that earth component also?

As you can see, I'm quite confused about this whole earthing thing.
Many thanks in anticipation.

Where these earth points actually creating the main earth bonding for the
electrical supply? Or, were they just equipotential bonding to the gas and
water mains?

You'll know if you look at the electricity supply head end. Is there a big
thick earth wire provided from it, or close by it?
