Ive disconnected the switch and its allowed me to have my sockets working for now, the light switch has 2 grey cables coming out with all kinds of wires like the one in the pictureBecause if one brown is doubled over, and two aren't, then that tells us which wire goes on it's own, and which wires go together in a terminal.
You double over a wire where only one wire goes in a terminal (usually).
The same will follow with blues, as it looks like a switched fused connection unit is probably needed.
