No... the kitchens do not have can openers or any kind of utensils at all.
They have kettles, microwaves, fridges/freezers, toasters and cookers. You will need to bring all your own cutlery, crockery, utensils, pans, tea towels etc.
There is plenty of cupboard space in the kitchens.
The bedrooms have a lamp, bed, desk, drawers, wardrobes, chairs and some have sinks (depends on residence). They have bed linen, but many only have blankets, so if you want a duvet you'll need to bring one and sheets for it.
I'd say you need:
Plates, bowls, tupperware,
Corkscrew (v useful!)
Duvet (if you want one)
Computer (if you have one)
Toiletries (and a bag if youre sharing a bathroom)
Extension lead (you get limited plugs under the desk)
Ethernet cable (for internet)
Home touches (posters, pictures, cuddly toys etc lol)
I think thats a pretty definitive list, but im sure i missed stuff lol.
