This one has 3 common lives, 2 common earths and what would appear

If there isn't a typo in the above something doesn't add up, please go and
re check (so far you make no mention of a neutral return) !

Oh yes - and 3 neutrals - knew I missed something

Cables are freely accessible from the roofspace.

My money is on me cutting the power, marking each wire, and pulling
back into the roofspace. Securely attaching to one fo the joists a
normal electical join box, and commoning up the lives neutrals and
earths there - then drop a single run down.

I've got some normal round 20/30a joint boxes, but it seems a bit of a
dodgy way to do this - don't doubt that it will work - just I've got
this feeling that I could be doing this another way/better way.
