Gas Bonding

Here we go again but at least it's not me this time :cool:

Ok call it something else, I'm sure people say Equipotential bonding very frequently where you work.

The bonding has to be visible, cross bond

Now come along you two please use the correct terminology, this time you only got a warning from the electrical police so consider yourselves fortunate next time it could be jail

If the pipe to the meter is plastic, then it's just possible that the gas pipe doesn't qualify as an "extraneous conductive part".

Although it is equipotential bonding, the correct term is main protective bonding (and has been for a number of years).

As director of the sarcasm bureau I would like to offer you the position of deputy director

First thing is to check whether the new gas service pipe is metallic (conductive) or plastic (non-conductive). If it is non-conductive then it doesn't need to be bonded.

Please do not give incorrect advice


All INTERNAL gas pipe work will be metal and as such will require a protective main bond


It is the responsibility of the home owner (or person ordering the work) to ensure compliance.


It is not BG (unless they put the boiler in). If there was no gas supply then it would be the boiler installer who should have installed the bond.


Does the OP have any paperwork from the boiler install?

If I remember correctly, the protective main bond must be attached to the gas pipe within a set distance (2 feet?) of where the pipe enters the house.

Seeing as the pipe is likely to be copper, why does it matter where the protective main bond is actually made?

Just curious.

Unless it was written into their quote, or spec as a task they would do on your behalf, it wouldn't be National Grid or British Gas' responsibility.

It is your responsibility as the homeowner because the bonding isn't being fitted to protect the gas pipe and metering, it's not there for gas safety. It's needed for the safety of your household electrical system, which is owned by you and your responsibility.

I stand by what I say.

If you have multiple paths to ground, then under fault conditions you could have different potentials on internal 'grounded' exposed metalwork depending on which 'ground' they are connected to. By bonding them, then all paths to ground have the same potential (equi-potential). A plastic service pipe cannot carry current and therefore cannot introduce a potential.

Bonding internal pipework is suplementary bonding not main bonding
