Should we open a SCB bank account now for our future retirement in Thailand?

So, opening a Thai bank account is difficult these days, but not impossible.

However, you can only open in person. Best to use an agent - Bangkok Bank seems to be the bank most interested and willing to set up a foreigner.

Expect to pay 1500-5000 baht fee to agent. Then an hour or so at the bank signing enough papers to kill two trees. However, you will exit the bank with a working debit card and their very useful ap installed on your mobile.

These are the conditions at the moment. In a few years, who knows?

All the best

Wait until you know exactly when you'll come. Things are changing here rapidly. (taxes)

Have you been to Thailand before?

Which part do you intend/hope to settle at?

A lot can happen in a 'few years,' both for you and in Thailand! There's no real upside to opening an account until you need it. Keep your money with you until closer to the time.

DO NOT EVER EVER LET THEM. TALK YOU INTO BUYING INSURANCE ‼️‼️‼️‼️

heard many people been taken for a ride and lost money

I would say yes. Get it over with early. Keep a small amount floating and use the debit card they give you. Keep aware of the fee structure every month.

Keep all your money in the UK until you are ready to go if your money disappears there's nothing you can do from this end

Nothing wrong with opening a bank sooner than later, and might save you some time and hassle later .. also rules here change a LOT.. people are finding it harder and harder to open an account..

But if you do open one then try to make sure you use it a bit so it's not closed on you as some other posts have mentioned.

Just wait do it later

If you can open one I'd recommend it. No need to put lots of money in it until you need to but at least you have it when required

Hard to open a bank account with a tourist visa. Not impossible

Up to you....

Also you don’t get any interest on your money in the Thai banks

What would be the point? You deposit a certain amount when you apply for a visa and that's it. You don't get extra credit for being a bank customer beforehand.
