Considering moving to England for work from Toronto

I visited London, England recently and I honestly really enjoyed my time there and was thinking about moving there from Toronto.

I've applied to jobs there and have a few interviews lined up. I am also finishing my online masters in computer science, in my final semester.

I am planning on leaving Toronto given how expensive it is. I'm at 100k and I can barely survive here and the atmosphere is very depressing. I was wondering if anyone here has worked in the UK and what their experience was like?
