Best route for main Electrical Bonding (edited)

[Dave V]

Hopefully someone can be of assisstance, I am not an electriction and not planning to do the job I am talking about but just want info.

I had an EV homecharger installed last week, the system cannot be activated yet as they could find no bonding or continuoity with the incoming water mains which is metal. I have to get an electriction in who will drill a hole through my wall and run an earthing wire around to my consumer unit and attach it to the sam bonding terminal that my gas mains is bonded to.

My water stop cock is four feet away from my cooker where a metal pipe comes through the wall for the pipework for my has cooker to be attached to. Can the electriction run a cable from the stop cock to the gas pipe behind the cooker rather than through the wall and around the outside of the house, would this do the same job.

Stupid question: my EV charger was installed, with a mini consumer unit (it needed a certain type of rcd and a spd), next to the main consumer unit.

The supply main is branched into this and the main consumer unit.

Where does your EV take its power from? Surely it needs to be fed in a similar fashion (dedicated circuit direct from the incoming main)?

Why have the installers made this your problem? Surely it's theirs?

I've asked for this to be moved to the electrical forum, you'll get more responses.

Where does the watermain enter your house, from outside, and is it a metal pipe that enters? Same for gas or oil pipes, if you have them.

Where is your house is the electrical incomer? (usually Company Fuse and meter next to each other)

Looking at the meter board, is there a label saying "Protective Multiple Earth?" Photos would be useful including any green-and-yellow, or bare, wires. What size are they?

Where is you house Consumer Unit?

Do you have wooden floors, with a void beneath them ventilated by airbricks in the external walls?
