Well I managed to fix my daughter's bathroom lights but what a
nightmare!

If you remember there are 10 lights in the bathroom with 4 switches.

The switch has 2 input supply cables with the lives connected to the
switch commons, neutrals connected together. Live and neutrals plus
earth go to each set of lights. No power on either of the input
cables although the neutral on one was connected I discovered.

Checked all the adjacent ceiling roses, no loose wires.

I jury rigged a supply cable from a socket to test the lights, this
tripped the main earth leakage RCD until I disconnected the input
cables.

Lifted up the floor boards in the room above. The bathroom has a
false ceiling fitted below the original 1920s ceiling. The wires from
the switch disappear into the false ceiling and there no way of seeing
where they go. [one of those cameras surgeons stick inside you would
have been useful]

I can only assume there is a junction box somewhere in the false
ceiling.

Anyway in the end I ran a new cable from the lighting circuit to the
switch and safely terminated the original input cables. The lights
now work.

Next time she can get a proper man in!

Your description is confusing. I doubt you have 2 incoming supply cables -
one will be a loop off to another room.

I used to resent Part P - now I see why it was introduced.

In this group people have asserted that lighting circuits are
arranged as rings. Assuming they are not trolling they presumably
believe this "fact".

That is what Dads are for. Did your daughter tap any money off you whilst
you fixed the problem?
