DD is at Exeter in her second year. As others have said, it's expensive. DS went to Sheffield and can't believe the prices for student houses in Exeter.
DD has just signed up for a house next year at £4500 a month (including bills) between 5 of them. It's an 11 month contract so you're also paying for months when there are no uni lectures. She's paying similar this year.
So, looking at accommodation costs for years 2 & 3 is important too if you're concerned about affordability.
Going back to year 1, she was in East Park. She got her first choice as she deferred a year. It was the most expensive but for her, modern en-suite accommodation was a priority over more money to spend going out. Room was tiny but lovely.
She had friends in Lafrowda who were happy with their choice but one in Duryard really didn't like it as it was too far out from campus for her. It probably didn't help that it was in the opposite direction to the others in the friendship group, so walking home after nights out was awkward. She secured a move to East Park after a few weeks.
Exeter was DD's absolute first choice uni, the only one she wanted really (location and course), and she loves it there so is content to pay what it costs. She worked for a year so had money behind her and worked all summer back at home.
She hasn't worked whilst at uni, she thought she might this year but I think the workload on her course is turning out to be too much. So, it depends on the course whether your DD will have time to work even if she can find a job. I'd suggest working in the first year if she can/needs to as it might get harder to fit in later on.
