Bonding to domestic water pipe (plastic)

[Dignam]

Good afternoon one and all. I, like many non-electricians are having issues regarding the need to have domestic water pipes (plastic entry to the property) bonded prior to an EV charger being installed. I have read a number of articles on this forum which quickly leave me behind with the information imparted. Hence my post. I have attached a picture of the stop cock with the blue plastic pipe connected to it. I have two queries which I hope can be answered for me:

1. Do the regulations require that the plastic pipe is bonded from the stop cock side? I doubt it but am not sure.
2. We have had a new kitchen fitted within the last year and at the top of the photo you can see an earth cable. One end of it is not connected to anything. Is this, do you think, a result of either the new kitchen being fitted and the fitter hasn’t re-connected it? I cannot see a termination connector. Or is it unnecessary and therefore never connected to anything and therefore answering point 1 above?

No requirement to bond the pipework either side of the stop cock with a plastic service pipe, unless the copper pipework then goes underground!
I suspect the earth bonding conductor may have been installed before upgrading to a plastic service pipe?

Very many thanks DefyG for that incredibly quick and affirmative answer. On closer examination of the earth bonding conductor it does appear to be "tarnished" or old and that may be the correct interpretation.

Thanks again.

The bonding cable was most likely connected to a stainless sink in the past.

I think that you are correct due to the position of the cable.

Thank you for taking the time to reply.
