In first year my rent was approx. 126/pw and in second it was 99/pw. Both were bills included (I think in 2nd year we did our own wifi, which was like £25/pm split between 4 of us)
I lived near the big Lidl both years and studied in Bede Island next to the Tesco Express so my general food costs were low, like <£40 a week probably. I avoided spending money on anything major. I didn't really buy new clothes etc. I think my biggest purchase during uni was new glasses frames.
I lived very cheaply in Leicester but I didn't do many social activities and wasn't a drinker really. I went to Uni in covid so there wasn't much on. I didn't have the opportunity to spend money on freshers events etc.
I lived on about £530/pm, plus occasional student ambassador work like open days (maybe £50/pm max). I lived very frugally at uni to avoid having to work while studying. Got away with it. But I was holed up in the library/computer labs basically all of the time. Living costs are very lifestyle dependent.
