but for now the EICR should be done to the edition on the CU/board when it was fitted.

Sorry, but got to disagree on that point - any EICR done today should be carried out according to today's regulations. If that were not the case and you came across an installation from 1888 with open knife switches and no earthing (and somehow it's hadn't degraded with age) you'd have to give it a clean bill of health as such things were permitted then. That's not to say that any difference from today's regulations would mean a fail - and knowledge of previous editions and some of the techniques they used to provide safety is certainly fundamental to deciding whether the installation is actually still safe to use, but there needs to be a common yard-stick to measure against, and that's the current edition.

agree - but the severity of the C1/2/3 has to match the actual danger present.

The same non-compliance  in a different place may be more or less serious.

And behind thick perspex knife switches can be both quite impressive and safe to operate if the PSSC is low.

I see both sides to this.


If EICR is to today's regulations then all installs that are checked become compliant.  However this will be at a cost.  Just look at the 18th edition with 4 amendments and a corrigendum that could lead to a lot of fails/unsatisfactory requiring remedial work and/or parts.  EG no SPD or a type AC RCD

On the other hand if a project was to last over five years it would surely straddle several editions and then it would not be compliant at hand over.  I agree the contract could say designed and installed to a specific edition for which an EIC could be issues but after that it would need a periodic EICR/inspection and testing.


So how is to move forward.  Well. JPEL64 could discuss it to the Nth degree or they could say something like EICR to the install edition or.
EICR to the install edition or the current edition after 20 years from install completion.

Either way people will need to compromise.


As a side note there is a real danger that a good install could be replaced with new compliant kit but poor workmanship.  BS 7671 Regulation 134.1.1

One can inspect, and find "not to current standard, however perfectly safe for continuing use" and 'C3' or even 'no code'

and if you like add a note "was fully compliant to wiring regs in 1969 edition" or whatever.

Most 'fussy' regs changes like wiring out of zones, non standard mechanics etc can be handled like that.
More serious stuff like 'exposed bus bar at head height' might benefit from site applied insulation or barriers erected.... which may still be not to current standard, but now safer...
