UK is famous for having poor dev rates. A coworker of mine transferred from Microsoft Beijing to Cambridge and had to take a pay cut because the payscale for the level he was at was actually lower there.

There are starting developers who get paid that much but it's not common. I hear most consulting firms pay about 1.5-6L, and Amazon pays 12-14L.

I have a decade of experience but get about half of that. Not all companies pay so much.
