New Sockets/Ring Main

[Torch]

Need to put in two new sockets and I want to extend the ring main. There is a concrete floor and power to the existing socket comes down the wall. Normally I would extend the ring main and come down the wall to the new sockets; however, in this case I cant' come down the wall (technically I could, however bathroom above and would entail taking up laminate floor, bath and shower tray to get where I would need to feed cable down) Would something like this be acceptable, where the ring main comes into the existing socket, I would replace the box with a dual box and two single sockets, then loop the ring main from one of the socket boxes round to the two new sockets then back to other single socket.

Your twin socket should have two cables coming into it, in order for that to be part of the ring main. (Even then, it could be a spur leading on to another spur). From your drawing it looks as though your twin socket is fed from a spur.

I assume that you marked the existing ring with one cable but it has two.

If there is no choice I would add a fused spur to the ring and from it on the load side add as many sockets you need, it is allowed as long the fuse in the spur does not exceed 13A.

I'm also not too keen on the right angle in the cables leaving the original socket, I assume this is a wiring diagram and not a layout drawing? The new sockets need to be horizontally in line with the original to keep within safe zones.

Thanks for the replies

Yes there are two cables, the original socket is part of the ring main.
Yes it is only a wiring diagram, sockets will be level, would look a bit weird if all uneven.
