… seems to have passed right by someone.
Don’t see what the problem is, thats pretty standard in most houses 
Is it a concept or an installation?

Loving the terminal strip and ancient woven insulation combo - nightmare fuel for sparkies.
Indeed, though typically the join is inside the box 
Ah, yes, that cable is unused though, to make things interesting, it was still live and terminated in a bit of chocolate block.
Doesn’t that melt the chocolate?

Dark chocolate being noticably firmer gets my vote.
And for older members Domino block.
Wago for us modern types

I’d be much more worried about the state of the cable than the fact there’s an exposed “chock block” junction - I really hope the stuff which is completely perished is not connected to anything.

See my most recent comment, that it was still live. It was the far end that was terminated in chocolate block.
Very good:grinning:
Chocolate is brilliant earthing. Or is it wired as a mouse exterminator?
I can see this becoming a long-running thread.
Anyway, today’s adventures in electricity include fixing the earth fault in the bedroom sockets, which turned out to be the result of using a bit of 2-core flex from the tableau to feed the sockets. Feeding the entire bedroom in reality as the lights and sockets are on the same circuit (this becomes important in a minute). Not ideal but I’ll need to live with it for the moment, I suspect.
Anyway, cable replaced to discover a new fault with zero resistance between live and earth when the bedroom light switch is set to on. See if you can spot the deliberate mistake or, as I prefer to call it, negligence verging on criminality.
Oh, I missed that, très drôle 
Yes, the oft used green and yellow switched live😬. Came across exactly the same last week in a friend’s house

Except somewhere, it’s attached to earth which they easily solved by not earthing the room
I suspect that there may be a long disused second switch for your bedroom light, perhaps above the ceiling where a pull cord switch used to hang over the bed. That black wire must be going somewhere, otherwise why use the green / yellow as a switched live.
I had a similar problem here, but fortunately a very rough repair to the ceiling gave away the position of the once present 2nd pull cord switch and its abandoned wiring which was of course still live.
The black is the live feed to the switch and the socket above it.
I think I would discard the (presumably 2 pin) socket, remove the red wire, cut back and make safe the blue, and then put some red tape around that yellow / green. Obviously the light fitting controlled by the switch must connect to the neutral / return somewhere else. In an ideal world one would remove the cable and replace it with something of a more appropriate colour, but in these old houses that is not always possible without causing a great deal of collateral damage.
My personal view is that anyone who uses a yellow / green for anything other than an earth should be publicly flogged. Having found one instance of such use means that any yellow / green found anywhere else must be assumed to be live in certain conditions until proven otherwise.
Good luck, and I hope that you have an old rubber car floor mat to stand on.

A safe baseline assumption with electricity is that no-one who was previously involved in an installation knew what they were doing (unless it was @badger, of course) and to assume the worst in all cases.
