I did invest in an angle grinder, for those that are interested the actual one was a Bosch PWS 700-115 Angle Grinder plus a concrete and stone diamond cutting wheel.
What a difference it made, what had taken me nearly two hours to do before with the drill, I was able to do in about half an hour, not only was it significantly faster, but because I cut down the sides of the chase and also the middle, when chiselled the pieces of brick just came away in one large chunk instead of thousands of small chards, it also meant that the rear of the chase was quite level in so far as it was all pretty much the same depth.
There was one downside of using the angle grinder, and that was dust, it got literally everywhere, the room was full of it, even though the window was open, took about 10 minutes for it to disperse so I could see what I had done. And as you may have noticed it did cover the wall too.
Overall though using the angle grinder and cutting disk made the job so much easier and quicker, while at the same time resulting in a better "finish" to the chase.
As soon as I'd finished I threaded the cable through the conduit, which proved to be a bit of a challenge as it was a tight fit, but by using a feeder wire I was able to pull the cable through the conduit, and reattach the switch for safety' sake.

Not much to say here really, all I had to do here was thread two cables through the conduit, obviously this conduit is much larger in diameter and could comfortably accommodate the two cables.
Yes I know when I took the picture I hadn't reconnected the light switch, but I did so before I left the room for the night.
Yes you are correct, it doesn't look pretty, but the main point is the cables are protected by the conduit, which is screwed to the wall, only the one P-clip used for this , but then it's a very short run from the skirting board to the socket. Better still the cable is protected when entering the socket by the collar which prevents the cable from rubbing against the sharp edges of the back box.
Correct at this point in time the socket is not attached, but only I ever go into the room at the moment and it's locked when I'm not in it.
