OK I'm pretty certain there is no permanent live going to the back room lighting circuit. I had a spare one gang switch which I attached to the black and red from the back room and got nothing at all.
There are only three wires going into the ceiling rose, I believe that those three wires go straight to the light switch because if they went to a junction box I should have a permanent live, and they can't be in a loop from the front room as there would be more than the three wires. Does this sound right?
So now the question is, can I wire the switch how I would like without the permanent live.
