Buying Property in Thailand From the UK: A Currency Guide

You can buy property in Thailand from the UK, but a foreigner can own a condominium outright while land is almost always held on a lease, and the money has to arrive in foreign currency. You pay in Thai baht, so the GBP/THB exchange rate sets your real sterling cost — and a move of a few baht on a seven-figure-baht purchase can swing that cost by thousands of pounds.

This guide explains what a UK buyer can and cannot own, why your bank issues a Foreign Exchange Transaction form, what drives the pound against the baht, and how to fix your rate before you complete.

Can a UK citizen buy property in Thailand?

Yes, but the structure depends on whether you are buying an apartment or a house. Under Thailand’s Condominium Act, a foreigner can own a condominium unit on a genuine freehold title. The limit is collective: across any registered condominium building, non-Thais may own up to 49% of the total unit floor area, and at least 51% must stay in Thai hands. A popular block can therefore reach its foreign quota, so the freehold availability of your specific unit is worth confirming before you commit.

Land is different. Thai law does not generally allow a foreigner to own land, so a villa or a house is usually taken on a registered leasehold — a maximum initial term of 30 years under the Civil and Commercial Code, renewable by agreement — or the building is owned separately from the plot it sits on. Some buyers use a Thai-majority company to hold land, but that route carries legal conditions and should only be set up with qualified Thai legal counsel. The route you choose changes the paperwork, not the currency mechanics: in every case you still convert sterling and settle in baht.

Why does the money for a Thai condo have to arrive in foreign currency?

Because Thai law ties a foreigner’s freehold condominium title to proof that the purchase money came from abroad. To register the unit in your name, the Land Department requires evidence that the funds entered Thailand in a foreign currency and were converted into baht inside the country — not transferred as baht from an offshore account.

That evidence is the Foreign Exchange Transaction form, or FET (previously the Thor Tor 3). Under the Bank of Thailand’s foreign-exchange rules, the receiving Thai bank issues an FET for an inward transfer of USD 50,000 or more; smaller amounts are documented with a bank credit note or certificate instead. The form records the amount, the foreign currency, the sender and the purpose. Get the purpose or the beneficiary details wrong and the bank can issue paperwork the Land Office will not accept, which stalls your registration.

This is where the mechanics of sending the money from the UK to Thailand matter as much as the rate. A specialist broker converts your sterling and remits the baht with the remittance coded correctly for a property purchase, so the compliance is handled and the money is not held up at the receiving bank while you are mid-completion.

What currency do you pay in, and what moves the GBP/THB rate?

You pay in Thai baht. Whether the developer quotes a price in baht or in US dollars, your transfer still has to arrive as foreign currency and convert to baht in Thailand, so the rate that decides your sterling cost is GBP/THB.

The baht is a managed float. It is quoted and traded primarily against the US dollar, and the Bank of Thailand steers it with reference to a basket the dollar dominates. In practice that means GBP/THB largely reflects the pound’s path against the US dollar — so the pound’s path against the US dollar is the single biggest external driver of what your Thai property costs in sterling. That dollar move is driven in turn by the interest-rate gap between the Bank of England and the US Federal Reserve, and by global risk appetite, which tends to lift the dollar and weigh on the baht in nervous markets.

You can check the live GBP/THB mid-market rate as a benchmark, and read our latest GBP forecasts for how the drivers may play out. No one can promise where the rate will go — the point is to size the risk before you are committed to a completion date.

How much can the exchange rate change the cost of a property in Thailand?

Enough to matter more than most of the fees you will negotiate. The price is fixed in baht; your cost is not, because it depends on the rate on the day you convert.

Take a condominium priced at THB 12,000,000. At an illustrative 44.00 baht to the pound it costs about £272,727. If sterling weakens to 42.00 before you convert, the same unit costs roughly £285,714 — about £13,000 more for a price that never changed. If sterling strengthens to 46.00, it costs about £260,870, saving close to £11,900. Across that 42.00–46.00 band the difference is nearly £25,000 on one purchase, and a routine 2% adverse move on the central figure is around £5,500.

The same effect hits a deposit. A 10% reservation deposit of THB 1,200,000 is about £27,273 at 44.00, and roughly £1,300 more if the rate has slipped to 42.00 by the time you pay it. (Rates here are illustrative round numbers to show the mechanism, not a quote.)

How can you protect your budget against a falling pound?

You cannot stop the market moving, but you can decide how much of that movement you are exposed to. There are four main tools, and most Thai purchases use a combination across the deposit, interim stages and the balance.

A forward contract lets you lock the GBP/THB rate as soon as your price is agreed, so the sterling cost is set regardless of what the market does before completion. It is worth understanding why a forward rate differs from today’s spot rate: the gap is the interest-rate difference between the two currencies, not a fee.

Thai timelines are rarely exact. Many apartments are sold off-plan, with payments made in stages as construction progresses, and a handover date can move. A window forward fixes your rate while letting you draw the currency across a range of dates, which protects you if the completion date slips by weeks or months.

What costs and taxes apply when buying property in Thailand?

At the Land Office, a Thai transfer carries a transfer fee plus either stamp duty or a specific business tax, and a withholding tax on the seller. Who pays which part is commonly split by negotiation between buyer and seller and should be written into the contract, and the Thai government periodically introduces temporary reductions, so confirm the current figures with your Thai lawyer rather than assuming. Budget for the transfer costs in baht and remember they move with the exchange rate too.

The UK side matters on the way out. If you are UK-resident and later sell the Thai property for a gain, you may owe UK Capital Gains Tax, and the gain is worked out in sterling by converting the purchase and sale into pounds at the rates on each date — so the exchange rate affects your eventual tax bill, not only your purchase cost. GOV.UK sets out the position on selling property that is not your main home, and foreign gains are reported through Self Assessment; the detail is tax, not something to guess at, so take guidance from a qualified tax adviser.

What currency mistakes do UK buyers make in Thailand?

• Transferring baht instead of foreign currency. Sending baht from an offshore account, or converting before the money arrives, can leave you without the FET evidence the Land Office needs to register a freehold condo.
• Letting the receiving bank set the rate. If the conversion happens at the Thai bank on arrival, you take whatever rate it offers. Fixing the rate before you send puts the cost under your control.
• Budgeting at the spot rate for a completion months away. An unhedged off-plan purchase leaves every stage payment exposed to a different rate.
• Forgetting the deposit is exposed too. The reservation payment moves with the market just like the balance.
• Ignoring the quota. Assuming a unit is available on freehold when the building’s 49% foreign share is already taken.

Once you own the property, you may also want to open a Thai bank account to manage ongoing costs, and many buyers fund the purchase from the sale of a UK home — both add their own currency timing to plan around. Our currency service for overseas property buyers is built around exactly these moving parts.

Frequently asked questions

Can a foreigner own a condo in Thailand outright?

Yes. A foreigner can own a condominium unit on freehold title, provided the building has not already reached its limit of 49% foreign-owned floor area. Land, and therefore most villas, cannot generally be owned by a foreigner and is usually held on a registered lease instead.

Do I have to send the money in a foreign currency?

For a freehold condominium, yes. The funds must enter Thailand in a foreign currency and be converted to baht inside the country, because the Land Department requires that proof to register a foreigner’s title. Sending baht from offshore can leave you unable to complete the registration.

What is the FET form and why does it matter?

The Foreign Exchange Transaction form is the document a Thai bank issues to record an inward transfer of foreign currency. Under Bank of Thailand rules it is issued for transfers of USD 50,000 or more, with a bank certificate used for smaller sums. It is the evidence the Land Office needs to register a foreigner’s freehold condominium, so the remittance has to be documented correctly.

What rate will decide the cost of my Thai property?

GBP/THB. Because the baht trades and is managed primarily against the US dollar, that rate largely follows the pound’s moves against the dollar. You can benchmark it against the live mid-market rate and fix it in advance with a forward contract.

Can I fix the GBP/THB rate before I complete?

Yes. A forward contract can fix today’s rate for a payment up to 12 months ahead, and a window forward lets you draw the baht across a range of dates if your completion could move — useful for an off-plan purchase where the handover date is not yet certain.

Will I pay UK tax when I sell a property in Thailand?

If you are UK-resident, a gain on selling the property may be subject to UK Capital Gains Tax, calculated in sterling using the exchange rates on the purchase and sale dates. Foreign gains are reported through Self Assessment. The rules are detailed, so take guidance from a qualified tax adviser on your own position.

How are my funds protected when I transfer through a broker?

Client money is safeguarded by Cambridge Currencies’ FCA-authorised payment partners, Currencycloud and ScioPay, held at a credit institution separately from company funds. Every transfer is completed by phone with a dedicated specialist who checks the payment details before the money moves.
