Most players on the concert circuit have their own projector and screen (Or one is provided by the venue) so that you can see everything the player is doing. (A lot also play facing the audience with either a projector as above or mirrors behind, which is the common position in Europe)

The main thing with the UK (And America as well with organ play) is that a lot of the players come from (And may even still play) a theatre organ background, (Or they began on a theatre organ) where the console is fixed and so you have no option but to have your back to the audience. (Just like a church organ)
