Which reminded me, why is it that a breaker of any type often seems, maybe
through never having been tripped for years can take too long to trip when
it finally does have a fault to protect against which can often mean a whole
fitting needs to be replaced due to overheating. Is it just build up of crud
or whatever, and should one say every few months manually trip these one at
a time to make sure they keep healthy?

I seem to be getting a lot of RCD failures when the RCD does not trip with
the test button of with the RCD tester.

But after manually turning the RCD off and back on it works within spec.

So give yours a test. It could save you from a belt.
