What would you guys do about the Main boding for the water then?

I had decided on 'further investigation', but if the incoming pipe is plastic does it need to have a main bond? I have tested the copper immediately after the plastic and somewhere along the line it is connected to the MET (approx 0.5Ω).

If the incomer was metal I would say I have to search more for the 10mm or run a new 10mm but it is plastic?
If the incomer is plastic and the rest of the installation is metal but does not go underground or get buried in walls then it is likely not extraneous, however if they have a boiler then the electrical earth connection to the boiler will almost certainly earth the water pipes and give you the low resistance reading.
 
At least who ever installed the JB's went to the effort of securing the wiring down with sticky pads and cable ties, a lot of sparks don't give a damn, shame he unnecessary snapped of the bottom part of the JB, although if the JB is fixed to the unit it would be a tough call if C2 or C3.
