0% loan/credit card to get student housing full payment discount?

So for the full year in my university student housing would cost 6.5K in 3 2-2.2K instalments but if i can pay the full amount at the start of the year i can get a £200 discount

is it advisable to try and get a 1 year 0% interest loan or credit card pay the full year on that put the money from the student maintenance loan (i understand i get this three times over the year as well) into a building society account (or similar) for interest and then pay it all off at the end of the year (with paying off the minimum required amount to keep the 0% interest during that time)?

if so how and where would be the ideal place to look? (i have never had anything on credit so i have no credit history)

i am entering as a mature student at the age of 24 into a 3 year course with optional placement sandwich year for the third year (4 years total with the third year at uni becoming the 4th)
