Not sure what you mean here.
Most, if not all banks, in the UK say you have to be a UK resident to open a new account. There have been quite a few threads on this.
In those threads there have been many reports of posters who have accounts and the banks know they live abroad and it has not been an issue.
Separately certain banks, Barclays springs to mind, have made it clear that they want to close accounts held by non resident account holders.
