I have recently had a new bathroom installed, but the plumber did not
install supplementary bonding. I have decided to do it myself, but am
unsure as to where to place the certain earthing connections. The plumber
has used between the water supply pipes and taps, a plastic connector.
Should I connect the supplementary bonding above, below, or in both places ?



All metal pipework should be bonded with proper earthing straps.

These should answer a lot of your questions:
