Some of the cheaper cities I’ve experienced are Belfast, Cardiff and Lancaster to name a few. Wales and NI are going to be the cheaper locations overall, but also cities in the north of England and Scotland are a bit cheaper too. But since it’s hard to choose by location due to unis I would say even if you look at cities in the south of England like Bath and Oxford, if you budget well then they can still be affordable to students. There are always cheaper places to discover within the cities and if you get a part time job whilst studying too then it’s manageable.
