Ask HN: UK salary survey?

I've seen a few HN posts about salary recently, but they've all been talking about the USA. I thought it would be a good time to discuss salaries in the UK.

What can a developer reasonably expect to make here? I understand it's an open-ended question, but any anecdotes, thoughts or opinions would be welcome.

Bonus question: I've posted before about how low salaries are for juniors [0]. Has this situation changed at all?
