No CPC’s, conduit doing it’s job, C2 or C3?

[Eric12]

Recently an old customer called me querying an eicr that had a C1 for no cpc in a conduit socket system; she found it odd as the last report from 5 year ago was fine. Had a look at the report and not one zs reading for any circuits; told customer report not worth a #### and to get another. Next report has a C3 for no earth conductor even thou Zs reading all good. I dont do eicr,s but feel I would do a better job of it than some of the carp I see on a regular basis!
