UK Earth bonding to Water

[Hemant007]

Greetings, I am homeowner and looking to confirm if I will need earth boding to water pipes.
There is already earth boding near Gas meter and the gas copper pipe enters the house.
Water main supply is via blue plastic pipe (MDPE) which then connects to plastic pipes and also some copper pipes (pipes under boiler are copper pipes, central heating pipes (flow and return pipes) are combination - somewhere copper somewhere plastic).
The consumer unit is metal box with RCD protection, the are 2x RCDs 30mAh, each with 5 MCBs.

Do I need water pipes earthen - the copper pipes under boiler and the some copper pipe sections under the kitchen sink with stopcock?

Thank you.

No.

Thank you for quick response, with my limited knowledge my understanding is also same as the main water pipe is not metal, I am not sure why an electrician will suggest to get the earth bonding to water done,
It makes me think that just adding some work to generate some income ! Sorry not sure, the electrician who suggested to do the earth bonding to water pipe as he can see some copper pipes under the boiler and under the sink.

The whole bonding thing is for extraneous metalwork. Ie, meaning outside the building.
If it’s a plastic pipe supplying water, then it is not metalwork… whereas a copper gas pipe is, and does need bonded.

Yes, thank you, Gas pipe is already bonded

An electrician suggested that - the copper pipes under boiler and the some copper pipe sections under the kitchen sink with stopcock need to be bonded.
If copper pipe goes under the wood flooring to reach radiators (not under earth ground) does that needs to be earth bonded ?

Did they carry out any testing of the pipework?

Out of interest only, why did you suddenly decide you needed to know if bonding was required to the plastic piping? just intrigued

no he did not test any pipe work, he could see some copper pipe, he could see copper pipe under boiler, I mentioned the main water supply is via blue plastic pipe, but he said the metal pipe inside the property needs to be bonded, so I feel he may just be making up some work to make money !

The only really way to know is to test it.
