When you move to a different country there are a lot of preparation, especially if you come from outside of the European Union (for now). However, the process is not complex if you arrive with enough energy to find your home here in this awesome country. Personally, I would recommend to write a list about what things you need before you move and try to start it before you move here.
-English phone number
-NIN Number
-Bank Account
-Accomodation
-Healthcare
