1950s meter tails

[JohnW2]

Originally the regional electricity board did everything, and was responsible for the meter and everything before it.

Yes, I understand that - but, even then, they were not 'responsible for' (or, probably, theoretically not even 'allowed top touch'?) anything 'after' (downstream of) the meter, were they?

Now, the DNO is only responsible for the supply and the cutout, the electricity supplier for the meter, cables and possibly an isolator if installed. Changed as a necessary part of privatisation, so that metering and electricity supply were separated from distribution and infrastructure.

Yes, I also understand that. However, even if that isolator were installed (by an 'electricity board') prior to the separation of responsibilities, I wouldn't have thought that the DNO would now accept any responsibility for (or 'have anything to do with') anything downstream of the meter, would they?

These are all real, not rhetorical, questions, since I'm trying to learn what is going on here!
