To be fair it’s just to stop any dodgy money so if you know a Thai citizen which obviously you do and get a certificate of residence then you’re sorted and Bangkok bank are the easiest for foreigners
I did it on January 31st. There is a requirement coming in from the U.K. where you have to document why you are leaving there.
I flew direct with Thai airways as didn’t want to risk any potential issues with any transit with certain airports etc.
If you are going to do it I suggest you do it quickly before the new system comes in the U.K. but of course you need to go through the process of having your visa and Coe and insurance and asq hotel all lined up before anything don’t forget the covid test and fit to fly certificate also
That is correct however according to the Thai government briefing this week they are now saying everyone coming from the U.K. needs one so I would check with the embassy first, or you would get refused in the airport
