The PIR and EICR have been required for years under the HSE to ensure our work places are safe, there has always been some leeway as some times turning things off is more dangerous to leaving them on, had this with an e-stop which when pressed dumped all air allowing a rail transport system to drop. It had to be modified so only some of the system dumped air.
I have done so many inspections testing gate switches actually stopped machines etc, with a far more complex inspection to what would be done in the home, and we have to remember the EICR is not domestic only. In some cases the report will be the basis for a discussion as to best option, and it may only report and not give recommendations, the extent of the report will vary, and the electrical supervisor or owner can select what he wants, I was often given a list of what to check, micro switches, residual current monitor (RCM) etc.
Even in the home the owner may select what is included, with this tread very likely the EICR was not for whole house but just the new installation for example. We should include the limitations in the report, there is even a code for it LIM, and of course one inspector may use LIM and another FI for the same item.
I think code C1 no one would argue much about, but potentially dangerous not so cut and dried, I wonder what code would be given to a safety switch of the wrong colour? This is what caused my accident, a black micro switch was removed, had it been the correct colour red or yellow it would not have been removed, so in hind sight wrong colour should get a code C2. It was poor design as could not raise the lid of the recycling machine without damaging switch, so switch removed to prevent damage.
However the point is the EICR is commissioned to high light dangers due to the condition deteriorating over time with domestic, and if installed to regulations current at the time it was installed, then there is really no requirement to code. We may mention some point which today is not considered appropriate any more, and may even code it as code C3, but we in essence do as we are told, and if my electrical supervisor says give so and so a quick once over to see any obvious faults, that is what I would do, and if he said we are due for a visit by HSE go over so and so with a fine tooth comb looking for faults then again that is what I would do. He who pays the piper calls the tune, which is why when LABC wanted to have an EICR for work I was to do, they selected and paid the inspector, and I was to pay them. As it transpired he changed his mind and accepted my EIC.
