    I have just had a smart meter installed and the engineer pointed out that the gas meter is not earthed.
    The gas supply by the way is by a heavy gauge steel pipe to the meter.
    It would be difficult to run an earth lead from the meter to the board but would be quite easy to bond to a radiator just a meter away. The central heating pipe network is all soldered copper and is bonded at all outlets and inlet to the combi boiler.

    No, you must connect the gas pipe as near as practicable to its point of entry to the premises to the Main Earthing Terminal of the installation.
    It may be connected near the entry point.

    Is the meter inside or outside?

    The main protective bonding (which is absolutely not Earthing) must connect it to the Main Earthing Terminal.

    I'l give you by way of an example why the radiator is not a good idea... The Boy and his brother, The Smaller Boy managed to rip the hall radiator of the wall. It was disconected and the pipe ends (under the floor) capped to stop the leak... and in this situation this would also have disconnected the earth bonding. Accidents happen, pipework gets replaced with plastic pipes and so on - all out of the control of the electrical and gas supply.

    The meter is inside, in a cupboard in the kitchen. A connection can be made easily to the meter outlet pipe but wiring through to the front of the house would be difficult as it would have to go up into the loft (we live in a bungalow) across the house but It would be a long wire! Also, the only main earthing terminal I can find is a clamp around the lead sleeved power input. This connects through to the breaker box in a bedroom and to the combi boiler and all it's pipes.

    That is one of the easiest possible options.

    If you want difficult, try a terraced house with solid floors, or a flat with the gas and electricity at opposite corners of the building.

    But non-compliant, and arguably illegal.

    I’m in the process of buying a 3 storey mid terrace that needs rewiring :whistle:. Don’t think I’d be using the ground floor floor but every room has laminate or tiles :mad:

    Steel? Is that the incoming pipe from outside, or is that the pipe that goes round the property?

    Given that the laminate needs to go anyway...

    Could we please have a picture of the meter pipes?

    In particular the inlet pipe from the ground to the meter.

    Bad move. Guess it is too late now though.

    Pity you didn't reads the threads on here about them first.

    Being picky in the meantime -

    If that is the case then it does not require bonding.
    However, likely it IS earthed which is why it requires bonding.

    It is actually that pipe which should be bonded.

    That might not achieve the desired objective.

    That bonding is not necessary and achieves nothing.
    For some reason, it is a favourite of plumbers.

    Maybe, like an awful lot of people, they struggle to understand the difference between earthing and bonding.

    In my experience, plumbers tend to 'bond', rather than earth - i.e. they join pipes together with G/Y cables (presumably with the aim of equalising their potentials), without making any explicit connection to MET, CPCs or any other explicit manifestation of the installation's earth. Obviously not 'Main Bonding', but nevertheless bonding, rather than earthing.
