Quite so. But you said 'Aircraft outside controlled airspace are uncontrolled. . . . . they can fly 2cm away from each other if they want to'.
I was simply pointing out that in the UK we can have aircraft outside CAS that are effectively receiving a service that is equivalent to control. And if two such aircraft get close enough together that wake turbulence spacing is an issue then, as far as I'm aware (and I haven't gone looking in the books so I stand to be corrected), WT spacing should be applied.
So yes, aircraft operating outside CAS and not receiving a RAS (or whatever it's called this week), can fly 2 cm away from each other. But if they are under a RAS then the controller should do the approprate thing wrt WT spacing if necessary.
