Don't I know it!
Bloody ring main has a live fault.
You would think its going to be a loose screw but no all the screw and
terminations are correct!
Now AFAIK there isn't a junction between the last good socket and the
next one so what are the odds of a cable fault?

If there's a cable break, is it perhaps near where it's terminated? It
gets bent round into the junction box, so that's a point of maximum strain.



I think it will become a radial as I don't fancy ripping walls down ATM.
