hi there - it looks like we are both in a very similar position in terms of evaluating a job offer and looking to move from london to switzerland. I am also trying to assess whether or not the offer I have been made is good enough - and my employer is also not helping me much by refusing to negotiate! It's so hard to get a feel for the cost of living, and the tax system looks very complicated.

my situation is a bit more tricky as I have a daughter, so have to factor in childcare etc, but the company has offered to pay for an international school and I love the idea of her learning to ski as part of her school programme! But her father will stay in london 9at least at first) so everyone is doing the whole 'too much upheaval', 'it's got to be a really fantastic offer for you to do that', thing.

Life is much easier if you are single, young and have no children, so i'd say just do it! you can always go back to london in a few years if you change your mind.

good luck!
