I've finally seen the report - 3 items as C2. It seems that the
electrician couldn't see any bonding to the pipework (I bet there is
somewhere, but couldn't say where. As far as I know the 17th edition regs
required this, and there wasn't anything mentioned 5 years ago);

I had one of these checks when I wanted to upgrade some electrical circuits
in a (not rented) house

the tester said

you need to add earth bonding

I said "it's plastic pipework, what are you going to do"

I got no reply.

I honestly don't know if there is a right answer.
