Before you fly: get your cards ready

Most cash problems in Thailand start in the UK. Ten minutes before you travel avoids nearly all of them:

• Use a fee-free card for cash. Otherwise your bank adds 2.75% to 2.99% to every withdrawal, and some add a cash fee too.
• Check your daily cash limit in your banking app. It decides how much you can take out in one go.
• Know your PIN. Your normal four-digit UK PIN works in Thai ATMs. If you've forgotten it, sort it out before you go.
• Check your app settings. Some apps block certain withdrawal types by default — Revolut users, for example, have reported needing to switch on magstripe withdrawals before some Thai ATMs would work.
• Turn on notifications so you see each withdrawal and any fraud alert straight away.
• Take two cards from different banks, ideally one Visa and one Mastercard, and keep them separately.
• Make sure security codes will reach you — your UK number working abroad, or app-based approval.
• Save your bank's overseas phone number somewhere other than your phone.

Most UK digital banks no longer need you to tell them you're travelling — they use your phone's location and their fraud systems instead. If your bank still has a travel notification option, it doesn't hurt to use it.

Choosing the right cash machine

You'll find ATMs outside almost every 7-Eleven, in every shopping centre, at bank branches, at airports and train stations, and along the main streets of every tourist area. Most are open 24 hours. The question isn't finding one; it's choosing well.

Best: a machine attached to a bank branch. If the machine keeps your card or doesn't dispense your cash, you can go inside — or come back when the branch opens — and deal with the bank that owns it.

Cheapest: an AEON machine. AEON has been widely reported charging ฿150 to foreign cards rather than ฿220. You'll find them in shopping centres and in Makro, Big C, Lotus's and MaxValu stores.

Fine: mall and 7-Eleven machines. They're owned by the major banks, charge the standard ฿220, and are busy and well lit.

Avoid if you can: lone kiosks and independent airport machines. Stand-alone machines in quiet streets carry more risk of tampering, and some independent airport ATMs have been reported charging up to ฿250.

Different banks' machines also behave differently with some UK cards. If one bank's ATM declines your card, the next bank's machine down the road may accept it without a problem.

Using a Thai ATM, screen by screen

The exact wording and order vary between banks, but a withdrawal with a UK card at a major Thai bank's machine usually goes like this:

1. Insert your card. Chip first, face up. Some newer machines also take contactless — follow the screen.
2. Choose your language. Look for "English" on the first screen, often in the corner.
3. Enter your PIN and press Enter or Confirm. Cover the keypad with your other hand.
4. Choose "Withdrawal". Ignore options like balance enquiry or transfer, which may not work with foreign cards.
5. Choose an account type if asked. "Savings" or "Current" both work for most UK debit cards. If one is refused, start again and pick the other.
6. Choose "Other amount". The preset buttons are usually small amounts. Type the full sum you want, in hundreds.
7. Read the fee screen. The machine tells you the fee — usually ฿220, or ฿150 at AEON. Confirm, or cancel if it's higher than expected.
8. Decline the conversion. If you're offered a pounds amount "at a guaranteed rate", choose to continue in baht.
9. Take your cash, then your card. On many Thai machines the cash comes out first and the card follows. Wait for both.
10. Take the receipt if offered, and check the transaction in your banking app before you walk away.

How much to take out — and which notes you'll get

Thai ATMs mostly dispense ฿1,000 notes, sometimes with some ฿500s. Because the ฿220 fee is the same whatever the amount, it pays to take out as much as you sensibly can each time:

The limit is usually whichever is lower: the machine's maximum per withdrawal (typically ฿20,000 to ฿30,000) or your UK card's daily limit (£500 a day on Chase, about ฿22,000; £300 on Starling and Kroo, about ฿13,000).

Large notes are a nuisance for taxis, street food and market stalls. Break them at 7-Eleven, supermarkets and restaurants, and keep a mix of ฿20, ฿50 and ฿100 notes for small purchases. Asking for an amount that isn't a round thousand, such as ฿9,500, can get you a ฿500 note if the machine has them.

Keep the bulk of your cash in your hotel safe and carry only what you need for the day. A ฿20,000 withdrawal is efficient on fees, but it's also a lot of money to lose on a night out or a boat trip.

When it doesn't work: common problems and fixes

If a Thai ATM won't give you cash, don't keep trying the same machine — repeated failures can trigger your bank's fraud checks. Work through this instead:

The most reliable fix of all is having a second card from a different bank, on a different network. If both fail, you can usually still pay by card in shops and hotels while you sort it out.

If the machine keeps your card

First, freeze the card in your banking app. That protects you whatever happens next. Then decide whether to try to get it back or simply order a replacement.

If you left the card behind after a successful withdrawal and the ATM is at a bank branch, you have a reasonable chance of getting it back. Travellers who have done it describe a similar process:

1. Go to the branch that owns the machine as soon as it opens — on Monday if it happened at the weekend.
2. Explain what happened, with the date and time.
3. Show your passport and the withdrawal in your banking app.
4. Describe the card so staff can match it.
5. Expect paperwork — copies of your passport and a short signed statement. Staff may ask you to test the card at the machine.

It isn't a standard procedure, so success isn't guaranteed, and a card retained after wrong PIN attempts generally can't be reclaimed. Machines in stations and stand-alone kiosks are much harder. If you can't get it back, order a replacement — most digital banks let you add a new virtual card to Apple Pay or Google Pay straight away, though you'll still need your backup card for cash.

Other ways to get baht

An ATM isn't the only option. Depending on how much you need and how long you're staying, one of these may suit you better:

Counter withdrawals with foreign cards are at each branch's discretion; reports vary between banks and branches.

Withdrawing cash at a bank counter

Some Thai bank branches will let you withdraw cash over the counter with a foreign card and your passport, which can be useful for a large amount — a deposit, a car or a month's rent. But it's inconsistent. Travellers report some branches doing it with a UK debit card and no fee, others charging around ฿220, others accepting only credit cards, and others refusing and sending them to the ATM.

If you want to try, go to a larger branch during the week, take your passport, and ask before you queue. Expect a minimum amount, and check the exchange rate being used — some branches use their own rate rather than your card network's. If it's a credit card, remember that a cash withdrawal usually attracts interest from the day you take it.

For very large sums, a bank transfer to a Thai account is almost always better than carrying cash, and for property, vehicles or business purchases it's the safer route.

Living or staying longer in Thailand

If you're spending months in Thailand, regular ATM withdrawals on a UK card add up — two a week for six months is over ฿11,000 in Thai fees alone. A Thai bank account changes that: withdrawals at your own bank's machines are generally free, and you can pay by Thai QR code at the stalls and markets that don't take cards.

You then move money from the UK in larger, less frequent transfers. For anyone retiring, working or living in Thailand, how and when you move money — and what happens to your pensions and savings — matters far more than the ATM fee.
