My Barclays account was schedule to be closed in January, because I am not UK resident.
I had my EU address with Barclays. When I phoned in and got customer support to enter my Swiss address I was able to keep the account (for the time being). Their guidance really seemed not very clear about non-UK and non-EU residents.
I emptied the account before deadline though

so as to not leave anything to Her Majesty in case the account would be closed nevertheless.
