Well to be fare to them both Belgium and Switzerland must be pretty poor at the moment for anyone with a pilots license be it high experience or otherwise.
And how can we say, your national stereo type will be working against you when applying in Britain. There are huge cultural differences in they way we "work" in Britain compared to main land Europe.
You could properly improve your chances no end by getting over here and applying from a British address and getting someone like Pilotpete to help you out with your CV. Go to a British language school instead of that International American crap which they teach in Europe and get your spoken/written English up to interviewing standard and then start reapplying.
