Anecdotal........Both electricians were members of the same scheme......one was not reaching scheme standards or the other one was working above those standards.
... or, of course, the latter may have been wrong (or of a legitimately different opinion) in relation to the alleged faults that he detected.
To me that suggests schemes are not very good at ensuring their members all work to the same standard.
To be fair, that is inevitable in any trade or profession - even those who can be shown, by assessment or whatever, to be
capable of working to the minimum acceptable standard will not necessarily always do so. The best most regulatory systems can realistically seek to do is to ensure that 'capability'
and to have systems in place which attempt to monitor whether people actually
do 'work to the standard of their capabilities' when not being assessed. Knowledge of the existence of such a system would, of course, also deter some from working below the standards required of them.
However, as I wrote, if we (society) want the industry to be regulated, the first step would have to be to establish a system of regulation that was 'mandatory' (hence industry-wide) - as I said, one cannot 'regulate an industry' if members of the industry have the choice as to whether or not wish to be 'regulated'. You certainly could not set yourself up as an airline pilot, doctor or even gas fitter and 'elect' not be subject to any of the regulatory systems which exist in those fields. The mere existence of Part P (which
does apply to everyone, electricians or not), per se, cannot seriously be regarded as effective 'regulation', since it is essentially not policed.
However, I can but repeat what I wrote to scousemark - namely that it's nothing to do what I want - whether or not electricians should be 'properly regulated' is a decision which society has to make. It really doesn't matter to me personally - I am capable and competent to undertake the electrical work myself if I so wish, and if I choose to employ an electrician I am well able to judge whether the work is being undertaken to an acceptable standard. Society may, of course, decide that they do not want/need any better regulation than now exists (which is their prerogative) - as scousespark pointed out, even with the present system, the number of fatal consequences of electrical work is (in terms of the 'big picture') tiny.
