My son and his girlfriend moved to Northern Ireland last summer and we have only seen them once since then. I am considering travelling over to see them soon. In Northern Ireland the rules are that one household can form a bubble with another household so we would be forming one bubble. We would have to isolate for 10 days though so wouldn't be able to leave their flat. Am I correct with my understanding of the rules and can anyone offer any advice on when might be a good time to attempt the trip?
