Posted this question in the central heating forum bu told to come here..

Is it mandatory to earth the gas pipe as equipontal bonding?
reason I ask is that it will be a tricky and complex job to route the earth wire.

Earthing and bonding are completely different things.

All extraneous conductive parts must be bonded (in this case main protective bonding).

Exposed conductive parts must be earthed.

Yes. It must be bonded if it is an extraneous-conducted-part (already earthed) which it almost certainly will be.

It should be connected where the pipe enters the properly - where practicable.

What is the problem, exactly?

the problem is routing it.. I'd have to go through wall, most likely up through the cavity wall up through loft.
the easy bit being getting it down to the MET

I think the length of run would be 20 odd.. possibly 30 feet.

It is NOT earthing.
Extraneous-conductive-parts require bonding because they are earthed.

Which pipe is only eight feet long?
Where does it run from and to?

slip of the tongue about earthing.. The copper pipe is the gas supply that runs from an exernally fitted meter, it enters the house through a sleeve in the wall then across the room inside (boxed in) and into a baxi bermuda indirect heating system approx 8 feet total length. to EQUIPONTALLY bond the pipe, I'd have a right old job routing the cable to the MET.

apologies for late reply, I dont get much opportunity to get online
