Most people get an email, but not everyone does... sometimes they get missed. But as long as you know it was delivered, your visa will be processed. I've never heard of them losing an application after it was delivered.
However, it can a few days to log the applications and send the emails, so it's unlikely you would have received an email yet anyway. It's only been 1 business day since your application arrived... and I'm not sure how many people will have been working in Sheffield last week.
I'd say you'll probably get an email sometime this week, maybe next week.
