Bangor University is ranked 1st in the UK for lowest cost of living for students (TotallyMoney 2019).
It is a UKVI/Home Office requirement that students have to show that they have £1,023 per month to cover their cost of living and other expenses. So, if you are here for 12 months please budget to have £12,276 available to you.
However, for general living costs, a VERY broad estimate for living in Bangor would be between £900 and £1100 per month for a single student.
The British Council has a useful website which can help you calculate your living costs whilst in the UK.
Another useful website which provides information on living costs and allows you to calculate your estimated expenditure can be found at:

If you have any difficulty in paying the fees, the following survey will guide you to where to ask for support or QR code:
