A clinic quotes a package in euros and the patient pays it from a sterling account. Somewhere between those two facts sits a cost nobody puts in the comparison.
The sizes are published, if you go and read the tariffs. A British debit card charges 2.75 or 2.99 percent on a non-sterling payment.[^1][^2] On a EUR 15,000 bill that is EUR 412 to EUR 449, which is larger than the gap between most of the quotes a patient is choosing between.
A EUR 15,000 clinic bill on a British debit card carries a 2.75 to 2.99 percent foreign transaction fee. That is over EUR 400. Which route actually costs least?
Nobody quoting you a package price has any reason to work this out. The clinic is paid either way, and the fee lands on the patient's statement weeks later, in a different currency from the one on the invoice.
The card fee is the one you can look up. Both banks publish it: 2.75 percent on a debit card, 2.99 percent on a credit card, applied to purchases, cash withdrawals and even refunds.
The bank transfer looks free and often is not. One bank's own tariff makes an online international payment free and a manual one 25 pounds, but the cost that matters is the exchange rate margin, which no tariff states as a number.
What complicates the case against cards is that most of this is avoidable. The same bank's online international transfer costs nothing, a euro payment inside the single euro payments area is free, and fee-free accounts exist. This is a charge for not checking, not an unavoidable tax.
What none of this can tell you is the exchange rate margin on a transfer, because no tariff states it as a percentage, or the size of a merchant's own offer at the terminal. Those two costs are real and unpublished, so the totals here are floors.
So the cheapest route is not a rule, it is a question: which of these four numbers has someone published, and which is being set at the moment you tap?
## The card fee is the knowable one
Two British banks publish the same structure. HSBC charges 2.75 percent on a debit card and 2.99 percent on a credit card for any non-sterling transaction, and it applies "whenever you do not pay in sterling".[^1] Barclays' International Banking tariff, dated March 2026, sets a single 2.99 percent Non-Sterling Transaction Fee "for using your debit card abroad when making purchases, withdrawing cash, or when you are being refunded".[^2]
Read that last clause. A refund attracts the fee too, so a cancelled procedure can cost money twice.
Cash has its own layer. The overseas cash withdrawal fee is 2 percent with a minimum of GBP 1.75 and a maximum of GBP 5 on a debit card, and 2.99 percent with a GBP 3 minimum on a credit card.[^1] The GBP 5 cap makes large withdrawals proportionally cheap, so the real constraint is the daily machine limit. Barclays notes a branch may need notice for counter cash above that limit.[^2]
## The transfer looks free and hides its price
On the same Barclays tariff an international payment made through online or mobile banking is free, while a manual payment is GBP 25. A euro payment inside the single euro payments area is free by either route. Receiving an inbound international payment is free from the area and free under GBP 100 equivalent, then GBP 6.[^2]
Those are the numbers on the page. The number not on the page is the exchange rate. The tariff says the bank calculates its rate "using the reference exchange rate for the Visa card scheme" for card transactions, and that sterling fees debited in another currency convert at "the applicable daily exchange rate".[^2] No percentage appears.
Three further charges sit outside the headline fee. A payment that has to be amended or repaired costs GBP 20, as does a payment enquiry or a recall.[^2] Dollar payments to banks outside the United States may carry a USD cover charge of GBP 3. And an overseas delivery charge may apply if the sender elects to pay all charges, with the amount varying by destination country; if the sender does not elect that, the recipient bears it.[^2]
That last one matters. If a correspondent bank takes a cut and the clinic receives less than it invoiced, the shortfall is the patient's to settle on arrival.
## The rule that covers cards, and not transfers
European law requires currency conversion charges on card payments to be expressed as a percentage mark-up over the European Central Bank's latest euro reference rates, and disclosed before the payer initiates the transaction.[^3]
The scope is narrower than it sounds. In January 2025 the European Banking Authority published an answer prepared by the European Commission on whether a mark-up counts as part of "all charges payable".[^4] It does not: the mark-up "is a means to indicate the currency conversion rate used for better comparability, but... is not considered a charge". The answer adds that the requirement applies to card-based transactions, not to credit transfers.
The official summary of the same regulation describes the transparency rules as applying to both card payments and credit transfers, with different timing.[^3] The two readings are not identical, and this article follows the narrower one because it is the regulator's own answer to the specific question.
Either way the position is the reverse of common advice. The route with a legally required, centrally benchmarked percentage is the card. The route people use for large sums is the transfer, where no percentage need be quoted at all.
## The terminal's offer, and the clinic's surcharge
When a card machine asks whether to bill in sterling, that is dynamic currency conversion, and the rate is not the bank's. HSBC tells its own customers plainly: "the merchant sets the conversion rate. Fees can often be high so in most cases it's cheaper to pay in the local currency."[^1]
There is no public tariff to check, because the rate is set per merchant. What the European rule gives a patient is the right to see the mark-up as a percentage before accepting it, and to decline.[^3]
Some clinics price the card route explicitly instead. One Antalya dental clinic's published price list is quoted in cash terms and states that card payments are 10 percent higher, which on a 20-tooth case moves GBP 3,335 to about GBP 3,670.[^5] That is a clinic surcharge rather than a bank fee, and it dwarfs both.
A money transfer service is the fourth route. Wise states that it uses "the live mid-market rate, and a small, upfront fee", with a discount above GBP 20,000.[^6] It publishes no single percentage, so the only way to compare it is to price the actual transfer on the day.
## How to work out your own number
Price all four routes on the same amount before you travel: card fee, transfer fee plus your bank's rate that day, transfer-service fee at mid-market, and the clinic's own surcharge if it has one.
Ask the clinic two questions in writing: whether the price differs by payment method, and whether the invoice amount must arrive in full. The second determines who absorbs a correspondent bank's deduction.
Decline the terminal's offer to bill you in your home currency, after reading the mark-up it must show you as a percentage over the European Central Bank's rate.
And if a refund is possible, remember it is charged too. On a 2.99 percent card, a cancelled EUR 15,000 procedure costs about EUR 449 going out and the same fee applied again coming back.
