And there re also plenty of reports of Expats known by their bank to be living in Spain and France being debanked since Brexit. And a friend of a friend, living in Thailand was surprise debanked in the UK by a bank who knew he was living in Thailand earlier this year. First he knew, was when he lost access to his account, had to fly back to the UK to get his money put in a different bank.
So you fill in the Thai forms, they contact your UK bank, and you then have the chance of losing your UK bank account. Gotta say, I'd rather risk non-compliance problems in Thailand than lose access to my UK bank account.
