The short answer

If you still have a UK address that genuinely is your home, a UK-registered Wise account remains the simplest way to hold pounds and send baht. Once you're registered in Thailand, Wise moves you to its Thai entity: you gain PromptPay and Thai QR payments, but with daily limits and no Thai ATM withdrawals.

A Thai bank FCD account lets you keep pounds in Thailand and convert to baht when the rate suits you — useful for pensions and property money — but it isn't covered by Thai deposit protection and it's expensive to send money back out. An offshore account such as HSBC Expat suits larger balances. Most expats combine two of these with a UK account.

Where you live decides what you can have

Every regulated provider has to know where its customers live, because that decides which licence and which rules apply. When you move to Thailand, you're expected to update your address — and that can change your account.

• Wise moves accounts registered with a Thai address to its Thai entity, regulated by the Bank of Thailand.
• Revolut doesn't offer its cards to people who live in Thailand, so an account opened in the UK may not keep working once you've moved.
• UK banks have their own policies on customers abroad — some keep you, some close accounts with a non-UK address.
• Thai banks open FCD accounts for foreigners living here, with the same visa and document checks as a baht account.
• Offshore banks are built for people living abroad, but check that Thailand is an eligible country.

Wise in Thailand: what changes in 2026

Wise is moving accounts registered with a Thai address to a locally licensed Thai company, regulated by the Bank of Thailand. The rollout ran from March to August 2026, and existing Thai-registered Wise cards are being replaced, with old cards cancelled.

The limits reported for Thai-registered accounts are:

• ฿800,000 a day in outward transfers abroad.
• ฿750,000 a day converting baht into other currencies.
• ฿30,000 a day in total multicurrency account payments, which may rise over time.
• ฿10,000 per transaction for certain baht payments.

Bank-to-bank transfers that don't sit in your Wise balance aren't counted against these limits. For most retirees, the practical effect is small: you can still send pounds from your UK bank to your Thai account through Wise. Where it bites is holding and spending — you can't use a Thai-registered Wise card for cash at Thai ATMs, and incoming payments from other people land in baht.

Thai FCD accounts: keeping pounds in Thailand

A foreign currency deposit (FCD) account is a Thai bank account held in a currency other than baht — pounds, US dollars, euros and others. For expats, it's a way to bring money into Thailand without converting it straight away, and to convert to baht only when you need it or when the rate is good.

Thai exchange controls decide what can go in and out. At Krungsri, for example, an FCD account can be funded by an inward SWIFT transfer, foreign banknotes (up to USD 15,000 a day without proof of where they came from), foreign cheques or transfers from another FCD account — and with baht only in limited cases, such as baht you earned in Thailand. Money can leave by SWIFT transfer, as foreign banknotes, to another FCD account or converted into baht.

• Not covered by deposit protection. Thailand's Deposit Protection Agency covers baht deposits only; Krungsri states plainly that FCD principal and interest are not protected.
• Minimum balances apply. Fall below them and a monthly fee — typically USD 10 — is charged.
• Cheap into baht, costly back out. Converting to baht is free at Bangkok Bank (at its TT buying rate); sending money abroad costs a transfer fee plus a withdrawal commission.
• Dormant accounts close. Krungsri closes non-resident FCD accounts left at zero for 365 days.

The accounts we'd look at

One for moving and spending, one for larger balances offshore, and one for holding pounds in Thailand.

Offshore multicurrency banking

Offshore banks in Jersey, Guernsey and the Isle of Man were built for exactly this situation: people who live abroad but earn, save or plan to return in pounds. They let you hold several currencies, pay and receive internationally and keep banking regardless of where you move next.

The trade-offs are entry requirements and protection. HSBC Expat, for example, requires £75,000 saved or invested within three months, a £120,000 salary, or existing HSBC Premier status elsewhere, and deposits are covered by the Jersey scheme up to £50,000 rather than the UK's £120,000 FSCS limit. If your savings are well above those limits, spreading them across banking groups matters more than which currency they're in.

For expats with modest savings, the combination of a UK account, Wise and a Thai account usually does the same job with no minimum balance. Our guide to international banking for Thailand residents explains how the pieces fit together.

Whichever accounts you choose, you'll be logging in to UK and offshore banking from Thailand — often on condo, hotel or café Wi-Fi. A VPN encrypts that connection, so your banking logins and transfer details aren't exposed on a shared network.

Which setup suits you

Holding pounds or baht: the currency question

The real reason to hold more than one currency is control over when you convert. The pound–baht rate moves constantly, and over months the swings can be large. At ฿44.38 to the pound, £10,000 is ฿443,800; a 5% move in either direction changes that by about ฿22,000.

• Keep your living costs in baht — a few months' worth — so a bad week for the pound doesn't force you to convert.
• Convert regular income regularly rather than trying to time the market; it averages out the swings.
• Hold larger sums in pounds if you may return to the UK or have UK costs ahead.
• Set a rate alert for one-off large conversions, such as a property purchase.
• Remember the margin — a bank's rate can be 1%–3% worse than mid-market, wiping out any gain from good timing.

Our guide to GBP to THB exchange rates explains how to tell the real rate from the one you're offered.

Seven mistakes to avoid

1. Assuming a UK app keeps working after you move. Check each provider's residence rules before you change your address.
2. Relying on a Thai-registered Wise card for cash. It can't withdraw at Thai ATMs — keep a Thai debit card or a UK card for cash.
3. Keeping large sums in a Thai FCD account. It isn't covered by deposit protection.
4. Letting an FCD balance fall below the minimum. Monthly fees add up, and dormant accounts can be closed.
5. Paying twice to convert. Sending pounds into an FCD account and then out again costs fees both ways.
6. Forgetting the visa rules. Retirement-visa money normally has to be in a baht account — check with Immigration before relying on an FCD balance.
7. Ignoring tax. Bringing foreign income into Thailand can be taxable for Thai tax residents, whichever currency it arrives in.

Getting cash when your multicurrency card won't

With Thai-registered Wise cards no longer able to withdraw at Thai ATMs, cash needs a different plan. A Thai bank debit card withdraws free at your own bank's machines. A fee-free UK debit card still works at Thai ATMs, although the Thai machine charges its own fee of about ฿220 per withdrawal, so take larger amounts less often.

For day-to-day spending, Thai QR and PromptPay cover almost everything, from street food to rent. Our guide to Thai QR payments explains the options, and how to withdraw cash in Thailand covers ATMs.
