That's exactly the kind of MCB.
Know of the whereabouts of any or why MK decided to start manufacturing them with the switches offset to every other device?
It'd probably be better to simply run the cables horizontally from the sockets themselves?
You could argue that with the hood, no one would be drilling there and therefore it'd be okay to stick the cable there, but that still wouldn't be in line with the regulations - you could use some...
The socket will be on a ring-main, where the cable loops between all the sockets on the circuit.
If you plan on tiling over the area, you'll need to use crimps to connect the cables together (red to red, black to black).
