It depends if its an extraneous conductive metal part likely to cause a potential (usually earth potential).
if the gas meter has a red insulating band or is fed by plastic it may not need doing , similar with the water.
i usually do 500V IR test between MET and the suspected part, anything below 23 K (23000) ohms i class as in contact with earth and could allow 10 ma of current to flow.

As above , a lot of more modern homes have a plastic water incomer usually a light(ish) blue pipe but I have come across black plastic as well which won't need bonding. You can test bwteen your MET and the stop tape to be certain.
Gas I normally find is supplied in metal pipe but again I have come across plastic as well
