Pulled the trim off today. When it happens, if I tap the lock assembly lightly, it starts working again. So it is looking very likely that is the problem.
Regarding the switch, I can hear a faint clicking noise from under the bonnet every time I press it. I also checked it with a multimeter and it was a dead short every time it was pressed.
It doesn't look like the lock assembly will come apart unless I drill out the 2 large rivets. I just removed it from the car and gave it a blast of compressed air to remove a few cobwebs in the mechanism, then a light spraying of WD40 on the moving parts.
Refitted it, and so far touch wood, it's working again without any problems. Time will tell though, it behaved for 4 days last time it played up, before stopping working again.
I'll leave the trim off for a while in case I do need to change the lock, as I've already broken a couple of securing clips.
I must say that the lock now sounds completely different when opening and closing the boot. A more positive click can be heard.
Apart from Vauxhall, does anyone know where I can get some replacement trim clips from? They're not the normal plastic serrated ones. They look like this, if its any help.
EDIT. It looks like the part No for the clips is 7703077477.
