I dont think I agree with you John.
I would say that any installation, irrespective of when installed and whether for rental or not, must be inspected and compared to A/ a normal inspection by the standard applying today (if not a rental) or B/ a normal inspection to the sopecifically named BS7671:2018 standard.
In either event any C1 or C2 or FI results in unsat.
I'm not really sure what you are disagreeing with, since what you've written seems very similar to what I wrote.
However, you do not address the debate we are having about what one regards as 'compliance with BS7671:2018' (or, indeed, any other specific edition,including 'the current'one'). Eric (and maybe others) try to argue that, since the Introduction of every version of BS7671 says that things 'are not necessarily unsafe for continued use' if they are non-conformant with the current version but complied with an earlier version, asking for 'an inspection to BS7671:2018' does not require full compliance with
the actual numbered regulations in BS7671:2018 ... and, as I said, I doubt that was the intention of the legislators.
It is difficult to imagine any C1 or C2 or FI differing under either of those alternatives.
If you're talking about the difference between BS7671:2018 and Amd 2 thereof, you're probably right. But what if one (eric) was looking at BS7671:2008, or earlier, citing the Introduction of BS7671:2018 as allowing him to do that? Coupled wth the indiv iidual judgement/discretion as to what is 'potentially dangerous', that could make the difference between C3 and C2 - for example in relation to some RCD protection.
I am still relatively suspicious that a few landlords might get more than one EICR unitil they get one that declares sat then ignore the unsat ones and let them become "lost". Even if that were specifically not allowed.
Sure, they may 'break the law', but that is true in any number of senses - but, as I've said before, that's only IF there is already a tenant in situe'. There seems little doubt that the law required a copy of the ('first') EICR to be given to the tenant (if there is one). However, as I've also said, if there is currently no tenant, the landlord is presumably free to go on having as many EICRs done as he/she wished, ignoring all until they get one which they 'like'.
Kind Regards, John
