Maybe I've missed the post, but when you went to the main stop cock to check for the bonding clamp, was it plastic or copper than on entry?

Its plastic at entry and copper everywhere visable although must be plastic under floors

There we go. Defo don't bond you'll be introducing a potential. With a plastic pipe.
