Indeed I am referring to a two-gang switch. And it could very well
happen. I'm in the process of hacking my ceiling to install projector
cables anyway.

So you're saying that I need to run two new cables, one from the switch
to each of the two lights?


What cables are in the switch already?
If there is just a single cable (Containing a black or blue, red or brown
and bare wire) you will need to run another one of these from the switch
into the ceiling.

Can you get access to the light fittings from above?

Also, what sort of fittings are there presently - ceiling roses or
something different? If you've got ceiling roses, how many cables are
wired in to each one? I'd expect one to have several (call this light
"A") and one to have just one cable (light "B") because B will simply be
piggy-backed on to light A, so that it goes on and off at the same time
as A.

You need to get a cable to run from light "B" all the way down to the
switch; and finally the 'piggy-back' cable connecting to light "A" needs
to be wired differently in order to energise light "B" continuously
rather than just when light "A" is switched on.

If you don't have roses, how many cables come through the ceiling - just
one for each fitting? If so, the connections will presumably be in
junction boxes above the ceiling, instead, and it's not so immediately
obvious which light is A and which is B.
