Interesting topic!
Well the UK market depends a lot on where you are. You can earn between £25k & £60k a year in London. The further north you go, the salary drops and mostly I have seen top ends of £30k. I'm on just under £30k which is about $50 or 43,000 euro's! Most of them that I see are in the £25-£40k range. It's an ok salary, unless of course you live alone 
Intersting to see salaries of places like the US and especially Australia as they are places I am considering moving to...well when I have a bit more experience!
