Bathroom Earth Bonding on Towel Radiator

I have replaced a traditional radiator with a new chrome towel radiator and need to re-atach the earth bond. Previously it was attached direct to the rad, but now I am unsure how to attach it to the new towel radiator.

Any suggestions please?. The new rad is connected by 10mm micro bore exposed copper pipes. Could I connect the earth to this and is a conventional 15mm earth clamp suitable on 10mm pipe?

Any advice greatfully received?

Radiators do not require supplementary bonding as they are not extraneous conductive parts.

They do if the copper pipework enters from outside the bathroom and the installation is not up to latest regulations ie RCD protection to all bathroom circuits, main protective bonding in place.....
If the copper pipes enter from outside the bathroom, the pipes need bonding, not the radiator.

Thanks for the clarification.

The radiator pipes will need bonding then as lights not protected by RCD.

So any thoughts on a clamp to connect the earth to the 10mm copper pipes?

any standard clamp can be used, if the end is too long then you can cut it back.
just make sure the wire is secure under the screw and the warning label is attached under the clamping screw nut, tighten the screw until it bites (holds the clamp so it cannot rotate) a little tweek to finish (don't overtighten as you don't want to pierce the pipe)
