Am I right in thinking that no matter how dysfunctional or prone to
nuisance tripping it is, a 30mA whole house RCD still meets current
regulations?

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

Those who want slavery should have the grace to name it by its proper
name. They must face the full meaning of that which they are advocating
or condoning; the full, exact, specific meaning of collectivism, of its
logical implications, of the principles upon which it is based, and of
the ultimate consequences to which these principles will lead. They must
face it, then decide whether this is what they want or not.
