Figuring out what you need, and what you don't when buying your uni essentials can be a little confusing. So it's worth checking out your university halls handbook to see what's already provided. A kettle and toaster for example are often already part of a student kitchen. And many digs even come with a sweeping brush and mop bucket. But this isn't mandatory.
Also bear in mind you can always wait until you get there for some non-essential items, and consider splitting the cost between flatmates for shared things such as an ironing board and iron.
