I have no idea whether the plates are privately owned or not. I have worked for firms where cherished plates were bought by the company for company cars, so it wouldn't be beyond the realms of possibility they're owned by Stagecoach. 
This isn't me doubting what you are saying by the way, I have no reason to doubt what you are saying.

Either way, if someone wanted to track these people down and find out where they live, it is possible to do so (legally), without needing a car number plate.
The fact Mr Medlicott's car has been returned to the lessor, means it will be harder for anyone to find him using his number plates/vehicle type.
