I did a board change for a mate recently, "does it need a rewire?" he asked, I thought for a minute then replied, "well it all depends" he looked at me then said, "depends on what, either it does or it doesn't" , He was amazed when I explained that as it stood, I could either pretend I was recently qualified and since it wasn't wired to the 18th ( the wiring is over 20 years old but not messed with) I could tell him it certainly needed a rewire at a cost of several thousand pounds, or I could use my experience, and my test gear and advise a few relatively cheap improvements, oddly enough he went for the second option.
Regarding unswitched sockets, I recently saw another EICR which had listed unswitched sockets as non compliant, which strikes me as a little odd because I distinctly remember reading something a bit back about isolation and iirc up to 16A you could simply pull the plug, is this some kind of new scam I wonder because I can think of a number of situations where an unswitched socket would be preferable to a switched one, freezers for example.
