Well, yes, by definition an opinion, but just made up for no reason with no justification.
I think that is wrong, and unnecessarily harsh.
If one starts from the fact that (rightly or wrongly) BS7671 regards (or has been told to regard!) plastic CUs as a potential fire hazard, then it's not unreasonable to feel that the extent to which it poses a 'potential danger' will vary according to the location of the CU and, for people who think that way, I'm sure that there will be varying opinions as to what locations cross a line to the point that they pose a sufficient 'potential danger' to require 'urgent remedial action'. You and I may disagree with NAPIT's opinion about that, but I don't think it is fair to say that their opinion is based on 'no reason' and has 'no justification'. Opinions are opinions.
Indeed, if I'm not mistaken, when we first discussed the issue here, at least a couple of people (was Simon one of them?) actually sympathised (agreed) with NAPIT's view about plastic CUs under stairs.
If I thought 2+2 was 5, that might be my opinion but no one should take any notice.
That's totally different, because it is a matter of fact (which you would have got wrong), not of opinion. If people undertaking EICRs stick to things that can be supported by correctly-cited regulations, then such 'errors of fact' shouldn't occur in the coding, but if they did something like coding a switch "because it was only 750mm from a bath", then I suppose that would be an example of a 'factual error'.
Ok. Needless to say, I disagree with the 'at least' part.
... and, equally needless to say, so do I - but, again, those are our personal
opinions. Again, I think one has to respect everyone's right to have opinions about such things, and I imagine that you would probably be able to find at least some people who sincerely believed that the absence of RCD protection in 2020 represented a sufficient 'potential danger' to warrant urgent remedial action.
In terms of the issues we've been discussing, the ideal would be for the coding of EICRs (at least, those for PRS properties!) to have absolutely no reliance on individual judgements/opinions. It's unrealistic to expect that to be completely possible, but the system could at least minimise the extent to which such individual judgement was required. Plastic CUs are a reasonable example - there could, for example, be a 'rule' that all plastic CUs should get C3s, or that all should get C2s, or that (like NAPIT) they should get C2s when in certain (well-defined) locations, but otherwise C3 etc. etc.
That's largely similar to MOTs. There will inevitably be some 'judgement' (e.g. the amount of play in a steering joint, or whether the amount of surface corrosion on a brake pipe was acceptable) but one would not want them to 'judge' the adequacy of tyre treads by 'eyeballing' them, or assessing the braking system by driving around and 'seeing how the brakes felt'. With MOTs, as much as possible is objective, rather than subjective, and I think that would also be desirable for EICRs (particularly 'PRS' ones).
