Hey, I know this is an old thread but in case you haven't found anything yet don't be disheartened. I was in a pretty similar situation to you in that I had a bad time at undergrad and got a 2.2. I got a good merit in an MSc two years later at a top five uni though and then they offered me several PhDs and DTC PHDs and even in subjects I had never looked at before, I'm an engineer and got offered Biology and Chemistry releated PhDs as well. I'm currently near the end of my PhD, but the problem I got and how I stumbled across your post, is that now when I'm applying for graduate jobs, I'm struggling to get past the HR initial screening, the HR staff or the software they use just see the 2.2 and instantly discard. Don't even read the rest!! It's getting to me a bit as an undergrad would be a piece of p**s now and the bachelors is no reflection of your current ability especially when you did it over 5 years ago.
