Unconnected bonding

[camerart]

Hi,
I've just had a new bathroom, where we removed old metal piping. The new piping is mainly plastic with some copper terminations.

When removing the bonding, I disconnected the earth bonding from the basin and inlet pipes and pulled it up into the loft, where the metal to plastic connection is.

I now notice that the bonding terminates in the bathroom light fitting, and the section that I pulled into the loft, goes nowhere. I assume that it should be directly connected to the consumer unit, is this correct.

There are metal water tanks in the loft, also other wiring. If i find another earth bonding, should i connect the bathroom one to it?

No. It does not go back to the consumer unit.
It is equipotential bonding, not earthing!! Please read the WIKI on these much misunderstood terms.

Plastic pipes do not need bonding.

In any case, are the circuits in the bathroom RCD protected? If so bonding is not necessary, assuming you have bonds to incoming services.
