I've been a Barclay's customer since I was 18 (so, 48 years) and I have had a Thailand address for the past 17 years.
A few weeks ago I got a letter to say that they require me to close my account before August 2023, or they will close it. They say that non-UK residents cannot hold an account for legal reasons.
My account is active - pensions being paid in every month, so it's not a question of a dormant account.
I have a Wise account and arranged for my pensions to be paid into it. Then I will transfer the money into my Thai account.
