Congratulations on your acceptance to Leeds!
So long as you are able to complete biometrics, pass the interview and naturalization exam and complete the swearing in ceremony you should not have any problems. I am assuming that you meet the physical presence and other eligibility rules, of course. Hopefully you can complete everything before you leave for the one year in the UK
