As long as both satisfy the qualifying requirements from the Law Society you can consider both. If you're not aware of this, the LS requires you to study certain core subjects such as contract, constitutional, property/land, criminal, torts, equity etc. Of course, if you don't intend to practice then you won't need to worry about them, but its good to keep your options open, especially if you're about to start your degree. Make sure the BA lets you study ALL of the core modules.
The Nottingham BA looks like its just a very felxible joint honours degree - you might enjoy doing modules from other subjects - politics, criminology, sociologoy, economics etc. They tie quite nicely into a law degree and to be blunt, they'll probably pull up your average grades.
