Some advice please. Recently installed a water softener and replaced most of the under sink pipework with plastic effectively isolating the remainder of the copper piping. There is an earth wire but I've noticed that the mains input pipe under the stopcock is not copper but some sort of black bitumen. I could connect the existing to copper to just above the stopcock but don't understand what this would achieve.

I don't think you can have a bitumen pipe ('plastic' water pipes are usually blue) so if it is bitumen covered metal pipe then it (and any metal connected to it) will likely require Main Bonding.
That is a conductor to the Main Earthing Terminal to equalise potential between the two.
