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.

 

[Hemant007]

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

 

[Hemant007]

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.

He wants to bond copper pipe that may or may not be joined together with plastic fittings?

I am looking to confirm if bonding is required to the copper pipes even when main supply is via blue plastic pipe, I feel the electrician who I met may just be making up some work to earn money !

More likely they don't understand the principles of bonding.

He wants to join the copper pipe regardless that the main supply is via plastic pipe, he says metal pipe inside property needs to be bonded regardless

It is common practice to bond copper pipe installs even though the supply is plastic , not a requirement but often worth running the cable as plans may change etc or there may be a cable there from a previous install and hey ho if its there just smash a clamp on anyway. Newer installs with plastic supply and only isolated sections of copper with most runs in plastic are another matter and you just wouldn't consider they needed a bond . Doubt the guy is trying to stiff you probably just being a bit 'rule of thumb' about it.
