I would suggest using your favourite search engine. If you type in your keywords "Free UK chat room" a list of good suggestions will show. If you type in a slight variation to that for instance "UK free chat room" you should notice that there will be a slight variation on the results. Search engines tend to put the highest priority to your keywords first in the list so I would generally start there. Without actually answering your question directly with a "free UK chat room" this is what I suggest.
Information you can give out on a online chat room would consist a address, email, phone numbers, age, etc.
