    Have things changed and I missed the memo.
    Let's start by saying I'm a fossil. I was trained the old way, were u went with a mate and went to night school and day release. Anyway, was on a domestic fault for a mate of a mate. I rocked up, kitchen ring tripping. Asked any recent works, holes drilled etc, non was the reply ( which was a fib, but no matter). Took both legs out of the board, circuit breaker tests ok, ring has 48k short. Went to split the ring mid point and noticed no earth strap from the box to the socket ( in my day this was mandatory). Found fault, someone had fitted an outside socket, full of water. Anyway back to the internal metal back box. The ring was in a new extension, one year old. So I advised them to get the sparks back to fix it. A few days later, customer rang me and said the sparks said it's not a requirement anymore. My question..since when

    Some would argue that the back box is not exposed so doesn’t need earthing.
    That aside, many sockets have metal rings around where the face plate screws go, these rings are attached to the earth terminals and the back box is earthed through the screws.

    As far as I'm aware, as long as 1 of the box lugs is fixed then there is no need to use a fly lead, mind you I'm a fossil as well so things may have changed, bye the bye your spelling is as bad if not worse than out current bad speller buzzlightyear, check out some of his posts, bring a tear to your eye:tongue::tongue::D

    Agreed on both point. But A) why have the termination screw o the box if it's not mandatory and B) why was I told to do it and have always done it since I was a lad?

    Not sure that all sockets have or have always had the metal ring around the screw hole.

    The termination block is there for when a switch is to be fitted, stops a floating earth

    The only time it is required is if the incoming cpc is steel conduit or a cable sheath such as MI or swa. If the box has lugs of which neither is fixed it is also required. To fit one when it is not strictly necessary is neither good or poor practice.
