Interesting. I recently turned down the opportunity to interview with a UK company because the compensation target was 120,000 pounds and I flat out told them, "that won't even get me out of bed in the morning." I have been talking with quite a few UK recruiters over the past few months and what I am noticing is that a lot of recruiters and headhunters in the UK just don't have access to the upper tier deal flow that pays the 200K salary. My current recruiter is under a strict "don't come to me unless they either have a super interesting problem in a revenue positive, stable company for 200K or a boring problem for 250K in a post-seed start-up." I have a standing offer with a company I don't want to work for for a little over 200K base compensation, so that's the target any recruiter has to hit. The work is out there, it just takes a while to find.

Thanks for the link to the salary calculator, useful to know what my take home will be when I am ready to make the move.
