Conduits are not mandatory if using T&E, most electricians have a set of push pull rods that can follow the existing cables from one light to another, it is then easy to pull another cable through the void if needed without pulling down ceilings, possibly without making too many, if any, access points through the ceiling to get around possible obstacles. This would be a simple job for an experienced electrician without too much disruption.

The only possible additional work could be the connections to the lights which may need to be changed to comply with regulations the individual lights should be connected with something like this, it is a Wago lighting box and Wago connector, ignore the gold coloured thing inside the box it's to help prevent flashing of LED's.

Late to the party, but I too believe this problem is moisture getting into the external lights, or rodent damage?

Get the handyman neighbour to fix it for a price, as he’s going to be there days replacing bits and pieces with no guarantee of success.

Also, first picture of board, I see a plug top with a short length of flex just cut off.
Remove the flex from the plug for safety.

I haven't read through this thread in detail, but I've seen that the immersion heater isn't working properly.
The lighting circuit fault could be a N - E fault (if I've skimmed that bit correctly), is on the same RCD as the immersion, and immersion heaters are prime candidates for having faults to earth.
Has anyone tried switching off the immersion heater at its double pole isolator.

Good spot on the plug top and flex.

If you are having trouble convincing people that the next door guy is not the right person for the job,

ask if you will be provided with a minor works certificate (electrical safety check) to show that the fault is gone and the circuit is safe to energise and continue using.

The immersion heater problem was only mentioned three pages in, we are pulling teeth here.

Lay people don't understand the connection. If the RCD trips when the lights are turned on, then it must be the lights that are at fault in their minds. They think the immersion fault is just a coincidence.
I've had more than one late night 'phone call from customers over the years trying to explain the possibility of a connection between the two. "But the immersion heater is turned off" "Is it off at the ISOLATOR" "No, it's on a time switch, as isn't on now" "TURN IT OFF AT THE ISOLATOR" "Oh, the lights work now".
