Qualified in electronics, only did electrical work as a DIY, now retired and enjoying life. Except when the RCD trips for no obvious reason...

I did consider that - until i saw the price of an RCBO - the board has 18 breakers...Rather than having lots of circuits on one RCD, perhaps consider changing the consumer unit to an all-RCBO board.
Firstly, if there are various circuits contributing to the leakage and tripping, it is far less likely to occur.
Secondly, if a circuit trips, you can see which one it is, rather than wondering which of several it might be.
Thirdly, the inconvenience of a trip will be much less if just one circuit trips.

Which brand(s) did you check?I did consider that - until i saw the price of an RCBO - the board has 18 breakers...
I have a Crabtree CU so I think I looked for something that would plug in directly replacing the MCBs - seemed to be about £30 eachWhich brand(s) did you check?
For example. Fusebox RCBOs are approx. £10 each.
Some makes are a lot more expensive.
I'd ditch the Crabtree board and start again.I have a Crabtree CU so I think I looked for something that would plug in directly replacing the MCBs - seemed to be over £40 each
I'm still hoping to find a fault that means I can keep the existing CUPerhaps a dual RCD board with the two highest leakage circuits on opposite sides?
But the fault might still be there...I'd ditch the Crabtree board and start again.
well... there are a couple or three, but as I mentioned I've not got around to the lighting circuits yet - they didn't show any leakage currentLet us know how you get on. Its a good job you did not mention any outside lights,,, eeek
Yes the fault might still be there, but at the moment it seems you don't know how many faults you have, or where they might be. The whole point of an RCBO board is to make each circuit independent, a fault on one won't affect another. I'd say it is a worthwhile improvement irrespective.But the fault might still be there...

I’d love to just rip it out but to spend the best part of a grand to narrow it down for fault finding seems a bit drastic.

That said, I've not seen details of the supply (TN-S, or TN-C-S, vs. TT) which might have some bearing on any consumer unit change.
