In the UK a suit has a different meaning than in the USA because almost everyone has worn a suit (or at least a shirt and tie) since they started school. I suspect that the reason that some jobs don't value a suit is because they align themselves with the same sentiments that causes school leavers to tie their ties to the school fence when they graduate. But there are still a lot of jobs in industries whose job is to keep things running, and in those industries a suit is considered normal attire.
