Am I right in thinking that no matter how dysfunctional or prone to

no, need a split CU at the minimum
And I would think an RCD that keeps nuisance tripping leaves the landlord open to the claim that the property does not satisfy the contract.

And in a 16 year old property that is to be let, does it NEED to meet
current regulations anyway?

It needs an electrical inspection every 5 years, and anything that fails to meet current standard at those times be brought within spec. So yes.
