I live in Scotland near Edinburgh, my first dev job I was earning £13k. It isn't super easy to break into development in the UK but within a year that had about doubled and that and learnt enough to be able to jump ship, which I did.

Now years later, I've happily earning more than the London average by contracting. I ate shit early on because I wanted to get somewhere in an economic time where the young are being screwed. I think it was probably worth it, but only until your experience and talent matures a bit.
