You may well find your experience would be acceptable for BA, but you're a bit light on hours and tonnage for Virgin (who have no shorthaul fleet). The conversion from FAA to JAA is complex and expensive, but has been covered here several times before. As a UK citizen, there is absolutely no reason why you shouldn't apply for jobs anywhere in the EU. As I see things, the job market in UK is better than in the US or the remainder of the EU, though possibly not as voracious as in the Far East. Pilots with experience on glass jets are in demand, and your prospects should be excellent. However - don't take my word for it. Contact BA, Monarch, Thomsonfly, easyJet, Ryanair and anyone else you might be considering and sound them out before you commit to anything.
