If you live near to campus I would (I do) Save myself a fortune living with my fiancé and my parents and I’m 26! And won’t finish degree till 30, however, we do have a deposit saved for a home for when I finish, and I have already done the socializing scene when I was your age.
With a degree already being £27000+ worth of debt already; adding extra on top of that to live away from home, when you have the opportunity to live at home may not be the smartest move.
You will have plenty of time for independence the rest of your life after your degree.
If you are eligible for the maintenance grant; save that money and spend the money you earn from working part time, that way, you may even come out of university with savings.
If still not sure, spend the first year at home, then if you feel you are missing out then move out in your second year.
I would say it is your decision but respect your parents views, as hard as it is to admit, 99% of the time they are right.
