AJJewsbury:Twisting words. Wiring , to a previous ed, (14th) is "not necessarily unsafe" This wiring is not unsafe.
I don't think it's logical to assume that wiring done to an earlier edition can automatically be considered to be safe. If that were the case we'd have to accept completely unearthed systems, basic insulation only, even exposed live part on the likes on knife switches - on the basis that that's what the 1st Ed allowed back in 1882.
Certainly a system to earlier standards shouldn't automatically be considered unsafe either - that would be equally illogical.
Indeed, and that is more or less what is written in the front of BS7671, when people claim the regs are not retrospective. I don’t recall the exact phrase but it is something like “installations carried out to a previous edition are not necessarily unsafe for continued service”. This indicates that they may be safe, or they may not be safe. It is up to the competent person doing the inspection on the day to make the judgement call.
it does seem a little over-zealous to award anything higher than a C3, but in the end of the day, rightly or wrongly to make the judgement. You could take the view that if you have been receiving a C3 or it’s predecessor every time for 20 years, then there has been plenty of time to improve things, especially in a commercial environment, although BS7671 does not set a time limit on things.
