I was hoping someone could clarify an example of a private lv supply?

Ok, but I'm talking about as a tester would you be happy to pass an installation if it conformed to a reg that was ancient, even though you know nowadays it would get shot to pieces under the 17th? And what about if this place was commercial and served the public surely then it would have to be approached as if it needed to be up to 17th??

If the installation conformed fully with the previous Reg's that prevailed at the time of installation, then it will, or should be just as safe as it was at that time. No later regulations can be retrospectively imposed on that installation....
