Earth Bonding Gas & Water Pipes

AncientMariner
Assuming the copper water pipe (above the stop-cock at end of MDPE pipe) is close to the gas pipe, is it acceptable/permissible for the earth bonding conductor to be a single 10 mm² green/yellow from the consumer unit to go to say the water 351 earth clamp, looped around the screw and then to the gas 351?  This without cutting the cable, so that it is one continuous length. Or if not looped around the crew, for a bare section to be opened up 3 strands and 4 strands and the screw fitted between?
Thanks.

    Yes - looping a bonding conductor uncut on a BS 951 clamp is acceptable (the uncut bit isn't even a BS 7671 requirement, but is recommended by BS 7430). Although if the water is plastic out of the ground (and the metal pipework doesn't later go underground or into to another installation) it probably doesn't need main bonding anyway.
