Adam, you are right. You
have completely misunderstood what a Basic Service is.
I suggest you go to the CAA's website and check up what services are available.
Air Traffic Services Outside Controlled Airspace | Air Traffic Standards | Safety Regulation
The CAA went to a lot of expense and trouble informing people of the changes ot ATC services outside controlled airspace (ATSOCAS). It all appears to have passed you by. You can get an interactive guide at
Air Space Safety: ATSOCAS 917
