So you should have a earth wire running from the water main to the fusebox, then a separate wire running from the gas, and or oil to the fuse box.

Not necessarily. You are permitted to use one conductor to connect to both pipes.

However, to the OP, I am a bit concerned: if the wire from the water pipe connects to the gas and does not go back to the MET, then that is wrong.

For PEB's, you cannot use pipework as the conductor.

What is a PEB and what actually is the MET? I mean, physically what is a MET? Main Earth Terminal yeah I get that, but what is this to look at? In my outcupboard it just has the earth from the stop cock and the earth from the fusebox attached to what appear to be the back of the main gas pipe coming into the property.

Bugger, really?

Wish I'd known that a week ago.!

Yes it is required to be green and yellow cable.

I know of no regulation which states that it cannot be sheathed or run in conduit.
