What your asking is know as supplementary bonding, not actually earthing but I think I know what you mean.

If you work to the BS 7671-2008 standards then there are certain criteria that if met can mean that you don't have to bond the copper pipes in your bathroom. These are outlined in the REgs at 701.415.2

If you don't have a copy then for the sake of a few pounds I would bond the bathroom if it were copper pipes.

I noted you also said that the water main was bonded, if you have gas in the house you should also bond that as well.

thanks so do i need supplementary bonding

yes, it will be easier and more reliable than trying to compose an argument for exemption.

I do not find your post very easy to read and in the time it would take to discuss it fully, you could have completed the supplementary bonding and moved on.
