Picking the right credit card before a big trip can easily save a frequent traveller £100 or more each year in fees and missed rewards. For UK residents, two of the strongest travel-friendly options are the Santander All in One Credit Card and the Halifax Clarity Credit Card. Both cut out foreign transaction fees, but they work in very different ways. Understanding those differences is essential before you rely on either card in Europe, the United States or further afield.

Key features at a glance
The Santander All in One Credit Card is a fee-paying cashback and travel card. It typically charges a £3 monthly fee and offers no foreign exchange fees on card purchases when you pay in the local currency, along with 0.5% cashback on eligible spending, capped at £10 a month. It is pitched at people who will use it for day-to-day spending at home and abroad, not just as a card to keep in a drawer for holidays.
By contrast, the Halifax Clarity Credit Card is a classic no-fee travel card. There is usually no annual or monthly fee, and it does not charge a foreign transaction fee on purchases in other currencies. Reports from comparison sites and money blogs indicate it also does not add an extra cash withdrawal fee overseas, although interest on cash begins from the day of withdrawal, so it still needs careful handling.
In practical terms, both cards let you pay in euros in a Paris restaurant or in dollars at a New York hotel without the typical 2.75% to 3% non-sterling transaction fee that many mainstream UK cards still add. The real decision is whether you value ongoing cashback and promotional 0% purchase periods enough to justify Santander’s monthly fee, or whether you prefer Halifax’s simpler, free-to-hold structure.
Neither card is designed for money transfers or heavy cash advances, and both come with variable representative APRs that depend on your credit profile. Before applying, travellers should always check the latest representative APR, eligibility criteria and fee tables on the provider’s own site, as these can change.
Foreign spending and exchange rates
For overseas purchases, both cards are built to be used in the local currency. When you tap your Santander All in One at a cafe in Lisbon for a €15 lunch, or your Halifax Clarity at a Tokyo convenience store for a ¥1,200 snack, the transaction is converted at the card network’s exchange rate. Travel money commentators note that these rates are usually close to the wholesale interbank rate, and significantly better than the dynamic currency conversion rates offered if you choose to pay in pounds at the terminal.
On the Santander All in One, you will not pay a non-sterling transaction fee on that Lisbon or Tokyo purchase, as long as you choose to pay in the local currency. On many competing UK credit cards, you might otherwise see an extra fee of around 3% added, turning a €100 restaurant bill into something closer to €103 in sterling terms.
The Halifax Clarity is similar in that it does not charge a foreign currency transaction fee for purchases. For example, if you spend $500 during a week in Orlando on theme park tickets, meals and rideshares, your Halifax statement will show those purchases converted to pounds at the Mastercard or Visa rate, without an additional percentage fee. This is why the card is frequently recommended on UK personal finance forums for European city breaks and longer trips.
In everyday use, the experience feels very similar. Where travellers go wrong is letting a shop or hotel convert the payment into pounds on the spot. With either Santander All in One or Halifax Clarity, you should almost always decline that offer and insist on being charged in the local currency to preserve the fee-free benefit.
Cash withdrawals and ATM use abroad
The biggest practical difference for travellers often shows up at the cash machine. With the Santander All in One Credit Card, cash withdrawals both in the UK and overseas generally attract a cash advance fee plus a higher interest rate that starts from the day you take the money out. Even though Santander does not charge a separate foreign exchange fee if you withdraw in local currency, the combination of any cash handling fee and immediate interest means this is still an expensive way to get travel money compared to a specialist debit card or local ATM-friendly current account.
Halifax Clarity is more cash-machine friendly, although still not free. The card does not typically charge a separate ATM withdrawal fee in foreign currency, which is unusual among UK credit cards. However, interest on cash withdrawals starts from the transaction date, not from the statement date. In real terms, if you land in Bangkok and use Halifax Clarity to withdraw the equivalent of £200 at an ATM, and then repay that amount online the same day, you will only pay a few days’ worth of interest, which might amount to less than £1. If you leave that cash on your balance for a full month, the interest cost rises quickly.
For a traveller who expects to rely heavily on cash in countries where card acceptance is low or street markets are common, Halifax Clarity can be more forgiving than Santander All in One, because you avoid an explicit ATM fee. But in both cases, the most cost-effective approach is still to use a fee-free debit card or local bank account for substantial cash withdrawals and reserve your credit card for purchases and hotel deposits.
Rewards, cashback and ongoing costs
The Santander All in One Credit Card tries to earn its keep through cashback and promotional interest-free periods. The headline benefit is 0.5% cashback on most everyday purchases, typically capped at £10 per month. That means a family that spends £1,000 a month on groceries, fuel, online shopping and travel bookings could receive around £5 back, more than offsetting the £3 monthly fee, as long as they pay off the balance in full to avoid interest charges.
On a practical travel example, imagine booking £600 worth of flights to Rome and a £400 hotel stay using the Santander card. With 0.5% cashback, you would receive £5 back on the flights and £2 on the hotel, totalling £7, which already exceeds the monthly card fee. Over a year that includes a couple of holidays and regular domestic spending, some cardholders find the cashback comfortably outweighs the £36 annual cost.
The Halifax Clarity Credit Card does not offer traditional ongoing rewards such as cashback or points. Its core value is cost avoidance: no monthly fee and no non-sterling fees on purchases, including in-person and many online transactions. If you primarily want a card to use for perhaps two weeks in Spain each summer, plus the odd online purchase from a European airline or an American software subscription in dollars, the absence of a fee structure may be more valuable than a modest cashback rate.
Travellers who already have a strong domestic rewards card, such as one that gives supermarket points or higher-rate cashback but still charges foreign transaction fees, sometimes pair that with Halifax Clarity: they use the rewards card in the UK and the Clarity card overseas. Others prefer the simplicity of putting all their spending, at home and abroad, on the Santander All in One and treating the monthly fee as a trade-off for always-on cashback.
Real-world travel scenarios: which card works better?
Consider a frequent city-break traveller who takes six long weekends a year in Europe, and spends heavily at home on fuel, groceries and online shopping. Suppose they charge around £1,200 a month in the UK plus £2,500 per year overseas. With the Santander All in One, 0.5% cashback on the domestic and foreign spending would add up to roughly £90 per year. After subtracting the £36 annual fee, they are still around £54 ahead, while enjoying fee-free overseas purchases. In this scenario, Santander’s card could be a strong all-rounder.
Now take a different traveller: someone who mostly uses a separate cashback card domestically and only wants a dedicated travel card for one or two big trips. Imagine a couple spending £2,000 during a three-week tour of the United States on hotels, meals and car hire. Using the Halifax Clarity card, they avoid a common 3% foreign transaction fee that would otherwise cost them about £60 on another card, and they pay no monthly fee. In this case, the savings are immediate and they are not sacrificing much by missing out on 0.5% cashback.
Cash withdrawals show an even clearer distinction. On a backpacking trip through Southeast Asia where card acceptance is patchy, a traveller might withdraw the equivalent of £100 in local currency four times in a month. With Halifax Clarity and prompt same-day repayments from a linked current account, the total interest might be only a few pounds. With Santander All in One, the same pattern could incur a specific cash transaction fee on each withdrawal plus higher interest from day one, making it noticeably more expensive.
Where both cards perform similarly is in typical holiday spending on restaurants, attractions and accommodation. Paying €80 for dinner in Barcelona or 1,000 Polish zloty for a ski chalet will cost about the same on each card once converted, assuming you always select the local currency on the terminal. The choice then comes down to whether you want your everyday UK spending to generate cashback on Santander, or whether you prefer to keep your domestic spending on a different rewards card and use Halifax Clarity as a specialist tool when you cross a border.
Eligibility, credit limits and managing your risk
Both Santander and Halifax assess applications based on your credit history, income and existing borrowing. The Santander All in One requires a minimum annual income (often quoted at around £10,500 or more) and may be less accessible if you have recent credit problems such as defaults or county court judgments. Halifax Clarity also relies on your credit profile and may offer a lower initial limit if you are new to credit or have a thin file.
In practice, that means a young professional planning a working holiday in Canada might find they are accepted for Halifax Clarity with a credit limit of £1,200, which is enough for flights and everyday card use, but not for high security deposits. Someone with a longer credit history and higher income might receive a £4,000 limit on Santander All in One, allowing them to guarantee a £500 hotel deposit in New York without tying up too much of their available credit.
It is also worth considering how each card fits into your overall financial safety plan. For example, Section 75 protection under UK law can cover certain credit card purchases over £100 when something goes wrong with a supplier, such as a hotel that never opens or a tour operator that fails to deliver. Both cards are standard UK credit cards, so eligible transactions should benefit from this protection, but debit cards do not. Many travellers therefore prefer to pay sizeable hotel, airline or car hire charges with a credit card even if they use a debit card for cash.
Finally, remember that using a large proportion of your limit right before applying for a mortgage or a new tenancy can make your credit file look stretched. If you are planning a major credit application in the next six months, think carefully before loading thousands of pounds of holiday spending onto a new card, whichever one you choose.
Practical tips for using either card abroad
Whichever card you pick, a few habits will help you get the most value. First, set up a direct debit to clear the full balance each month wherever possible. On Santander All in One, this ensures that any cashback you earn is genuine profit rather than being wiped out by interest. On Halifax Clarity, it helps minimise the interest on any cash withdrawals and keeps your credit utilisation ratio healthy.
Second, get used to checking payment screens carefully. In tourist hotspots from Prague to Phuket, terminals and ATMs may default to charging you in pounds instead of local currency. With both Santander All in One and Halifax Clarity, paying in pounds abroad usually removes the fee-free advantage, because the foreign bank or merchant sets a poorer exchange rate. Always look for an option that mentions “charge in local currency” or shows the local amount in bold.
Third, download and register for the bank’s mobile app before you travel. In real-world terms, this lets you freeze your card quickly if it is lost on the metro in Paris, check whether that unexpected £150 charge is simply a hotel holding deposit in New York, or make an extra payment to cover cash withdrawn in Mexico to reduce interest. Travellers on long trips often log in once a week over hotel Wi-Fi just to keep an eye on things.
Lastly, carry a backup payment method. Even reliable cards can occasionally be declined due to network issues or fraud checks. Pairing Santander All in One or Halifax Clarity with a separate debit card from a different bank, or with a low-limit second credit card, means you are not stranded at a petrol station in rural Italy or at a ticket machine on the Tokyo metro.
The Takeaway
For UK-based travellers, both the Santander All in One Credit Card and the Halifax Clarity Credit Card are powerful tools to cut the cost of spending abroad. They share the key advantage of waiving foreign transaction fees on purchases when you pay in the local currency, which can save roughly 3% on every restaurant bill, museum ticket and hotel stay compared with many standard credit cards.
The Santander All in One stands out as a strong all-rounder for people who spend regularly on a credit card at home and overseas. Its 0.5% cashback on most purchases and promotional 0% interest offers can comfortably outweigh the £3 monthly fee for many households, especially if they place their everyday spending through the card and pay off the balance in full. It is less compelling if you rarely use a credit card domestically or if you expect to draw significant cash abroad.
The Halifax Clarity shines as a specialist travel card. With no monthly fee, no foreign transaction fee on purchases and no separate overseas ATM fee, it is ideal for travellers who mainly want a low-cost backup card in their wallet for trips. It is particularly useful for those who occasionally need to withdraw moderate amounts of cash from foreign ATMs and who are disciplined enough to repay these withdrawals quickly to limit interest.
The best choice depends on your pattern of spending. If you want a single, everyday card that also works well on the road, Santander All in One may be the better fit. If your primary goal is a simple, fee-free travel companion to sit alongside an existing UK rewards card, Halifax Clarity remains one of the most attractive options. In either case, using the card intelligently and avoiding dynamic currency conversion will have a far bigger impact on your travel budget than the brand name on the plastic.
FAQ
Q1. Which card is cheaper for spending abroad, Santander All in One or Halifax Clarity?
For purchases in local currency, both cards work out similarly, as neither usually charges a foreign transaction fee. The difference is that Santander has a £3 monthly fee but offers cashback, while Halifax Clarity generally has no ongoing fee but no rewards.
Q2. Which card is better for ATM withdrawals on holiday?
Halifax Clarity is typically better for occasional overseas cash withdrawals because it does not add a separate foreign ATM fee, although interest on cash starts immediately. Santander All in One can charge a cash advance fee plus interest from day one, so it is usually more expensive for cash.
Q3. Can I use these cards for online purchases in foreign currencies from the UK?
Yes. Booking a hotel on a US website in dollars or paying for a European airline ticket in euros from home should be treated much like in-person foreign spending, typically with no non-sterling transaction fee. Always choose to pay in the foreign currency at checkout rather than in pounds.
Q4. Is the Santander All in One Credit Card worth the £3 monthly fee?
It can be worth it if you put enough spending through the card. Regular spending of around £600 a month or more, including travel, can generate cashback that outweighs the £36 annual cost, especially if you also benefit from promotional 0% interest periods.
Q5. Does Halifax Clarity offer any cashback or air miles?
No. Halifax Clarity focuses on eliminating foreign transaction fees and keeping the pricing simple. It does not usually have a cashback or points scheme, so it works best alongside a separate domestic rewards card.
Q6. Will using these cards abroad affect my credit score?
Using any credit card abroad is treated much like using it at home. Paying on time and keeping your balance well below your limit can support a healthy credit profile. Persistently high balances or missed payments can hurt your score regardless of where you spend.
Q7. Are hotel deposits and car hire holds safe on these cards?
Yes, but they will temporarily reduce your available credit. A hotel in New York might place a £200 hold and a car hire company in Spain might add another £500. If your limit is modest, this can restrict your ability to spend until the holds are released.
Q8. Should I notify Santander or Halifax before I travel?
Most UK banks, including Santander and Halifax, no longer require formal travel notifications for common destinations, but it is wise to ensure your contact details are up to date and that you have the mobile app installed in case the bank needs to verify transactions.
Q9. What happens if my card is lost or stolen abroad?
You should immediately freeze or block the card through the bank’s app or by calling the emergency number on the back of your statement. Both issuers can arrange replacements and will investigate any fraudulent transactions, normally reimbursing you for unauthorised use.
Q10. Can I rely on just one of these cards for a long trip?
You could, but it is safer to carry at least one backup payment method. Even reliable cards can be declined due to network issues or security checks. Many travellers carry either Santander All in One or Halifax Clarity plus a separate debit card or another credit card from a different bank.
