Bedding - you will need to bring your own duvet, pillows and sheets for your bed. If you are in courts then a double duvet is appropriate, and if you are in lodges then a single will do.
Kitchen Stuff - HF kitchens have a microwave, an oven, a kettle and a toaster, so you will need to bring everything else that you will need for cooking and washing up (pots/pans, cutlery, plates etc).
Food - You will need to eat whilst at uni so bring some food! Sainsbury's is a minute drive from HF so you can always buy from there when you get here.
Work Stuff - Pens, paper, laptop, books and anything else you may need for your lectures is a must.
