Do I Need to Bond?

[The Jeep]

Gents - I have just fitted a kitchen with metal sink, copper pipes to taps, with copper fittings on pipework (i.e. no plastic).

I have run an earth equipotential cable from CU to water main stop-cock, in kitchen cupboard.

Do I still need to put additional bonding on pipes below sink?

No.

Although a room with a bath or shower is required to have equipotential bonding, this is not now required in a kitchen. You are probably thinking of some old rules when this used to be done.

The main earth bonding you have done to the metal pipe on the consumer's side of the stop cock is correct (10mm) and there should also be one on the incoming gas pipe.

If there is a gas boiler, it seems the corgi people like to see all the gas and water pipes bonded together at the boiler, and to the earth of the electrical supply to the boiler and controls, but this is not an electrical regulation, it seems to be a gas safety thing (and why not)

Thanks for that, John D. That seems to make sense.
