Are you planning to live in halls at Nottingham or live at home ?
Nottingham is a cracking University and, if you live in, you may find you're getting the best of both worlds: a great university experience, with the chance to meet lots of people, join societies etc; whilst still having the option to easily go home if/when you want.
Academically wise, it's also considered very highly by employers and usually is there/thereabouts in that list of 7/8 "target" universities that the investment banks/law firms/consultancies etc. consider.
However, fully appreciate it if what you want to do is go and experience living in a completely new town/city etc.
In terms of clearing options, obviously it's not possible to know if your chosen subject / universities will be in clearing yet. However, you could see if they are offering places in UCAS Extra - that might be an indicator if they still have spare places
