First thing I'm going to say is that with aerospace everyone starts off wanting to go into the space industry or being a pilot. I'm now going to tell you to avoid focusing on that and to look at aerospace as a whole because that's what you're going to be studying for 4 years.
Second if you ignore that is look at unis with a decent chunk of space curriculum, off the top of my head I'd name Surrey and Southampton, there's probably a few more. From studying there, I also know that Sheffield offers additional lectures on space topics and intends on introducing more space modules in the future so you might want to watch out for them too. Also consider that there aren't that many opportunities in the UK to get into the space industry as a graduate, it may be worth looking at other countries (France is probably your best bet and the US your worst due to citizenship restrictions).
