I am based just outside London, many of my clients work in central london/city and say they are not going back for many months, or are now going to be working from home several days of the working week permenantly, and doing maybe 2 in the office, this is why I am doing OK, as I am based local to where they live, I am not relying on commuters. I think it is all down to my location.
No one seems to be worried about coronavirus, and most of my clients dont even know anyone who has had it, so that does not seem to be an issue.
