Thanks will follow adviceElectrically they are different ideas.
In short, reducing cable size half way along a run requires adding extra protection which would be a right pain to implement in this situation. (Wrestling 2 x 6 sq mm wires that aren't quite long enough into a fused spur would be rather torturous)
I wouldn't even entertain doing it this way, when it's such a trivial matter to run it into a new MCB (~£3) in the consumer unit. A simple gland in the side, and off it goes.
I'd imagine you could find a sparks that would let you run the cable and leave a couple of meters of cable for him/her to test, connect, and do the required paperwork.
