Never Pay in Pounds Abroad: Here’s Why
The short answer: never pay in pounds abroad. Choose the local currency instead. When a card machine or ATM offers to charge you in pounds, decline. Providers call this prompt dynamic currency conversion (DCC). It lets the merchant set its own, less favourable exchange rate instead of using your card network’s rate. The pounds option usually costs more. Sometimes it costs a lot more, even though it sounds like the safer, more familiar choice.
What’s actually happening at the card machine
Many overseas shops, hotels, and ATMs offer dynamic currency conversion. If your card comes from the UK, the machine offers to convert the charge into pounds on the spot. You see the exact sterling amount before you approve the payment.
That sounds convenient, and that’s the point. The catch is who sets the exchange rate.
If you choose local currency, your card network (Visa, Mastercard, or similar) converts the charge at its own rate. That rate tracks closely to the wholesale interbank rate. If you choose pounds, the merchant’s payment processor sets the rate instead. That rate almost always includes a built-in markup, and the merchant and its DCC provider profit from it.
How much does paying in pounds abroad cost you?
What the research found
The markup isn’t small.
A German consumer testing organisation checked DCC pricing in 11 countries. Paying in home currency raised the price every single time, by about 2.6% to 12%.
A European consumer group found that DCC typically added a few percentage points to the fair market rate. Standard card network conversion stayed within a fraction of a percent of the real interbank rate.
At ATMs, researchers have documented markups as high as 12% in parts of Europe. Financial outlets have reviewed extreme cases with markups of 18% to 20%.
Why people still pay in pounds abroad
Even so, many people still choose it.
An academic study on consumer behaviour found that nearly half of international customers pay in their home currency. Converting through their own bank is cheaper in most cases.
That’s not because travellers are careless. Card machines make the convenient option feel like the safe one. In reality, it benefits the merchant most.
The cost on a £100 purchase
Here’s what that looks like on a £100 purchase:
| Choice at the card machine | Who sets the rate | Typical markup | Cost on a £100 purchase |
|---|---|---|---|
| Local currency | Your card network (Visa, Mastercard, etc.) | A small network markup (usually well under 1%), plus your card’s non-sterling transaction fee (typically around 3%, or 0% on travel cards) | £100 to £103 |
| Pounds (DCC) | The merchant’s payment processor | Roughly 3-7% on average, sometimes higher. Your bank usually doesn’t add its own fee on top. | £103 to £110+ |
On a single coffee or souvenir, that difference is small change. The gap is narrower on a standard card and wider on a card with no non-sterling fees. Add it up across a hotel bill, a few dinners, and a week of cash withdrawals. It becomes real money for no benefit at all.
A real-world example of paying in pounds abroad
Say you’re checking out of a hotel in Rome, and the bill comes to 1,000 euros. Assume the market rate that day is 1 euro to £0.85, so the bill equals £850. Rates change daily, so treat these numbers as an illustration.
- The front desk asks if you’d like the charge in euros or pounds.
- You choose euros. Your card network converts the 1,000 euro charge at a rate close to the market rate. Your card then adds its non-sterling transaction fee, typically around 3%. You pay roughly £875.
- You choose pounds. The hotel’s payment processor shows a “guaranteed” total of £893, with a 5% markup built into its rate. Your bank usually won’t add its own fee on top, because the charge is already in pounds.
Same bill, same hotel, same room. The only difference is the button you tapped, and it cost you about £18. With a card that charges no foreign fees, the gap grows to about £43. Multiply that across a week of hotel stays, restaurant bills, and cash withdrawals. The local-currency habit can easily save you £100 or more without changing anything else about how you travel.
Where the offer to pay in pounds abroad appears
The offer to pay in pounds abroad appears in three main places:
- Card machines at restaurants, shops, and hotels. The cashier or the machine asks you to confirm a currency before you tap or insert your card.
- Hotel checkout. The front desk may ask if you’d like to pay your final bill in pounds.
- ATMs. The screen offers a “guaranteed” sterling amount before you confirm a withdrawal. This is one of the more expensive versions of DCC. Researchers have documented markups as high as 12% in some markets.
The wording varies. You might see “Pay in GBP?” or “Pay in your home currency?” Some screens simply show two totals side by side. Whatever the phrasing, the rule stays the same: pick the currency of the country you’re standing in.
Heading to Europe or the US?
The same rule applies across the eurozone and in the United States, two popular holiday destinations for UK travellers. If a machine offers pounds, choose the local currency instead. That means euros in the eurozone and US dollars in the US.
What if your card charges foreign transaction fees?
Most UK credit and debit cards charge a non-sterling transaction fee, typically around 3% of the purchase. Some travellers accept DCC on purpose. They reason that a charge in pounds avoids that fee.
In practice, paying in pounds abroad rarely saves you money. Your bank usually waives its fee on a pounds charge, but the DCC markup tends to run higher than that fee. On a standard card, the gap can be narrow. On a card with no foreign fees, local currency wins clearly.
The better fix is a card with no non-sterling transaction fees. Several UK travel credit cards, prepaid cards, and digital bank cards charge none. Get one before you travel, then always choose local currency, whatever the machine asks. Providers change their fees often, so check the current terms before you go.
Taking cash out? Credit cards often add a cash withdrawal fee on top, typically 2% to 3%, and may charge interest straight away. Check your card’s terms before you use an ATM abroad.
The one rule to remember
When a card machine, hotel desk, or ATM abroad asks you to choose a currency, choose the local one. Choosing local currency over pounds abroad takes one extra second, and it’s the choice that most often works in your favour. If a machine defaults to pounds, ask the cashier to charge you in local currency.
Frequently asked questions
Is paying in pounds abroad a scam?
Not technically. Card network rules require merchants to disclose the exchange rate and ask for your consent. The problem isn’t that DCC hides the rate. The problem is that its rate is worse than the alternative. Many travellers accept it without realising there was a better option.
Does this apply to ATM withdrawals too?
Yes. ATMs abroad often offer the same choice as card machines. DCC markups at ATMs can be just as high, and sometimes higher.
What if the receipt only shows pounds, with no option?
If the machine gave you no choice, contact your card provider. You may be able to dispute the pounds charge through a chargeback. Card network rules require merchants to let you choose. A charge in pounds without your consent may be reversible.
Will declining DCC slow down my checkout?
No. It usually takes a single tap or a one-word answer to the cashier. The only extra step is remembering to select the local currency.
Does this affect debit cards the same way as credit cards?
Yes, DCC applies to both. Be especially careful at ATMs. A debit card withdrawal in pounds can lock in a poor rate on the entire amount you take out.
