Programming culture is not hypertoxic. Maybe it is in the United States in the UK pretty much everyone just sits down and gets on with it.
However my experience with a couple of UK programmers was they were alright.

Indian developers in the UK have essentially got won the Willy Wonka Gold ticket as the salaries in the UK are much higher and they just work 12+ hours a day and keep their heads down. There is a higher number of female developers in my experience come over. But that could be just my impressions.
