I forget how wide the joists are off the top of my head but a board runs
across two gaps, i.e. uses three joists. To thread the wire through the
joists with a drilled hole, which is what I should do, would take a rewire
and installing junction boxes. I may have to take the hit and do so
properly. I was wondering if there was a quicker alternative without being
detrimental to the structure.

Can you unscrew the covers on the ceiling fittings below? If so it
might be possible pull the wires up through the ceiling, route them
through the joist and push them back down into the ceiling fitting.

Is this much different than a 'notch' in the joist?

Well you would need a router. It looks like the IEE regulations forbid
laying cables in notches on the top of joist like this anyway.

Junction boxes are 50p and 100m 1mm^2 T&E £10.25 at Screwfix, it might
just be easiest to route new wires between the joists to the edge of
the loft and cross the cable over the joists at the edge.
