Just watching a YouTuber who says he's lived in Bangkok for the last 10 years, and doesn't have a Thai bank account?! Is this a wind up, it seems most of the posts on here are about the importance of opening a Thai bank account?

I have a HSBC account in the UK from which I transfer my monthly min 65k Baht for my retirement extension. I’m seriously thinking of relocating permanent to Thailand in the next year or so. If I become a non UK resident, can I still hold my UK account. I would like to keep the account as my pensions are paid directly into this. Anyone have experience of this situation.
