-Kitchen wares are provided by halls to the extent of large stuff like pots, pans, appliances, etc. but you might want to bring some cups, bowls, and the like. Even if the halls provides those, students like to keep them in their room for an eternity so...
-Bring some fancy dress stuff. You'll be doing a tonne of that in 1st year with pub crawls, parties, etc.
-Usual schoolbooks, pads, pens, computer, etc.
-Bedding. God knows how many people have arrived at halls without it.
-Normal personal stuff - clothes, wash kit, gym gear, etc.
-BOOZE!
