I fear it could be this then, maybe. It’s the kitchen circuit tripping now with everything unplugged other than oven, boiler, dishwasher washing machine. There looks some historic water ingress on one wall near appliances/sockets

You can narrow it down further with lengths of cable but you might want an electrician to do that because you're going to have to do a fair amount of disconnecting/connecting and testing to narrow it down.
Once you know where it is you should be able to connect the ring temporarily to avoid the problem.

Just to clarify though, you could have damp in the walls or under a floor that has destroyed the insulation of the cables over time and that can be tested with an insulation resistance tester once the problem circuit and part of the circuit is diagnosed. I had one of those recently tripping the ring in a basement flat. In this case the tell tale sign was rusty backboxes.
