Compare Travel Money Options in the UK: Cash, Cards, and Prepaid Currency Cards Explained
TL;DR Summary: UK travellers have four main travel money options: exchanging cash before departure, using a standard bank debit or credit card abroad, loading a prepaid travel money card, or using a fee-free multi-currency digital bank card. Airport bureaux de change are consistently the most expensive, applying margins of 5% to 15% above the mid-market rate. Online cash ordering from providers such as the Post Office or Tesco Travel Money delivers materially better rates. Fee-free travel cards from Wise, Revolut, and Starling Bank offer the lowest total cost for card-based spending. A combination of a fee-free card and a small cash float represents the optimal strategy for most UK travellers.
Introduction: Why the Method You Choose Matters
The method by which a UK traveller accesses foreign currency has a direct and material impact on how much they receive in return for their pounds. Foreign exchange is a commercial product, and every provider, from a high-street bureau de change to a digital banking app, earns revenue by applying a margin between the mid-market interbank exchange rate, the fairest benchmark for currency conversion, and the retail rate offered to consumers. The size of that margin varies enormously between providers, from less than 0.5% on the most competitive digital platforms to more than 15% at the least competitive airport outlets.
For a UK traveller exchanging GBP 1,000 before a two-week holiday, this difference translates directly into purchasing power. At an airport bureau charging a 10% effective margin, the traveller receives the equivalent of GBP 900 in foreign currency. At a fee-free card applying the mid-market rate, the same GBP 1,000 converts at full value. Understanding the cost structure of each travel money option is the foundation of making a genuinely informed decision before any international trip.
Exchanging Cash in the UK
Exchanging pounds for foreign currency cash before departure remains the most widely used travel money method among UK travellers, particularly for destinations where card acceptance is limited, where tipping in cash is customary, or where rural or market-based spending is anticipated. The main channels for buying foreign cash in the UK are airport bureaux, high-street bureaux, bank branches, post offices, supermarket travel money counters, and online delivery or click-and-collect services.
Airport bureaux de change, operated by companies including Travelex, ICE, and Moneycorp at UK departure terminals, consistently offer the weakest exchange rates available to UK consumers. Effective margins at airport outlets can range from 5% to 15% above the mid-market rate depending on the currency and provider. The convenience premium of last-minute airport exchange is real and substantial, and purchasing currency at the airport on the day of travel rather than ordering online in advance typically costs GBP 50 to GBP 150 more per GBP 1,000 exchanged depending on the currency pair.
Online foreign currency orders from providers such as Post Office Travel Money, Tesco Travel Money, and Moneycorp delivered to home or collected in-store offer considerably better rates than airport equivalents. The Post Office charges 0% commission and offers rates typically within 1% to 3% of the mid-market rate for major currencies, with the effective margin improving for larger order amounts. Tesco Travel Money, which won Best Travel Money Provider in the Personal Finance Awards 2025 and 2026, operates over 350 in-store bureaux and offers competitive rates with free collection on orders above GBP 500. Both providers offer the ability to sell back unused currency at the original purchase rate, a valuable guarantee for travellers uncertain about how much they will spend.
High-street bureaux de change operated by foreign exchange specialists such as Travelex, Eurochange, and independent operators typically offer rates between the airport and online benchmarks, with margins commonly in the 2% to 5% range. Rates improve meaningfully for larger exchange amounts, as most providers apply tiered rate structures that reward higher-value transactions. Ordering in advance and collecting in-store, rather than transacting as a walk-in, typically produces a better rate from the same provider.
Using a Standard Bank Debit or Credit Card Abroad
Using a standard UK bank debit or credit card for foreign currency purchases or ATM withdrawals abroad involves two categories of charge. The first is the foreign transaction fee, typically between 1.5% and 2.9% of the transaction value, applied by the card issuer on each non-sterling purchase. The second is the exchange rate used by the card network (Visa or Mastercard), which is close to but slightly above the mid-market rate, typically within 0.5% to 1.0%. In combination, a standard UK bank card may apply an effective total cost of 2% to 4% on foreign currency spending.
Cash withdrawals from foreign ATMs using a standard UK bank card carry additional charges: the foreign transaction fee, a cash advance fee charged by the card issuer (which may also trigger immediate interest on credit cards), and potentially an ATM usage fee charged by the local machine operator. The combination of these charges makes standard bank credit card cash advances at foreign ATMs among the most expensive ways to access foreign currency. Standard debit card withdrawals are less punitive but still typically cost 2% to 3% per transaction in combined fees.
Prepaid Travel Money Cards
Prepaid travel money cards allow UK travellers to load foreign currency before departure and spend or withdraw abroad at the locked-in conversion rate applied at the time of loading. Major providers include the Post Office Travel Money Card, the Travelex Money Card, and the Caxton Card. These cards are not linked to a UK bank account, which provides an additional layer of financial security against card fraud or theft abroad.
The Post Office Travel Money Card supports up to 22 currencies with contactless payment capability and integration with Apple Pay and Google Pay. It charges no transaction fees for in-currency spending, and the card is managed through a dedicated app. The Travelex Money Card supports up to 22 currencies and allows the exchange rate to be locked in for the initial currency load, providing protection against subsequent rate movements during the trip. There are no spending fees for purchases made in a loaded currency, and the card is issued by PrePay Technologies Limited under Mastercard licence and is FCA-regulated.
Prepaid cards are best suited to travellers who want to budget precisely for a trip by loading a fixed amount at a known rate, and who prefer the security of a card not linked to their main bank account. However, the exchange rates offered at the point of loading are typically not as competitive as those available through fee-free digital bank cards, and unused balances may incur inactivity fees if left loaded for extended periods.
Fee-Free Digital Bank and Multi-Currency Cards
Fee-free digital bank cards represent the lowest-cost option for card-based spending abroad for most UK travellers. The Wise multi-currency card converts currencies at the mid-market exchange rate with a conversion fee from 0.43%, charges no foreign transaction fee, and offers two free ATM withdrawals per month up to GBP 200 before a 1.75% fee applies. The card supports over 40 currencies and can be topped up in GBP with conversions timed to a favourable exchange rate.
Revolut charges no foreign transaction fee and converts at interbank rates within monthly plan limits, with a 0.6% fee beyond the limit and a 1% weekend surcharge on standard plans. Standard plan account holders receive free ATM withdrawals up to GBP 200 per month. Revolut's premium plans offer higher limits and additional features. Starling Bank's debit card charges no foreign transaction fees and no surcharge for overseas ATM withdrawals beyond whatever the local ATM operator may charge, with conversions processed at the Mastercard exchange rate which is very close to mid-market. Monzo charges no foreign transaction fees and applies the Mastercard exchange rate on purchases, though ATM withdrawals above GBP 400 per month outside the EEA incur a 3% fee.
Dynamic Currency Conversion: Always Decline
Dynamic Currency Conversion (DCC) is a service offered by many foreign payment terminals and ATMs that allows the cardholder to pay in sterling rather than the local currency. The machine identifies the card as UK-issued and presents a choice between paying in the local currency or in GBP. DCC should always be declined. When a UK traveller accepts DCC, the terminal operator applies its own exchange rate to the conversion, which includes a markup typically between 3% and 10% above the mid-market rate. This produces a materially worse outcome than allowing Wise, Revolut, Starling, or even a standard card network to handle the conversion. Selecting local currency at every terminal and ATM is the single most reliably cost-saving travel money behaviour for UK card users abroad.
Recommended Strategy for UK Travellers
The optimal travel money strategy for most UK travellers combines a fee-free digital card for the majority of spending with a modest cash float for situations where cards are not accepted. A Wise, Revolut, or Starling card handles card purchases and ATM withdrawals at the lowest available cost. A small amount of cash ordered online from the Post Office or Tesco Travel Money in advance covers taxis, markets, tips, and rural spending where card infrastructure may be absent. Airport exchange should be reserved only for genuine emergencies where no alternative is accessible at the time of need.
Frequently Asked Questions
What is the cheapest way to get travel money in the UK?
Fee-free digital bank cards such as Wise, Revolut, and Starling offer the lowest total cost for most UK travellers, converting at or near the mid-market rate with no foreign transaction fee. For cash, ordering online from the Post Office or Tesco Travel Money and collecting in-store or having it delivered offers significantly better rates than buying at the airport. Airport bureaux de change are consistently the most expensive option and should be avoided where possible.
Is it better to use cash or a card when travelling from the UK?
For card-accepting environments, a fee-free digital card is the most cost-effective option and eliminates the risk associated with carrying cash. Cash remains necessary for tipping, markets, rural areas, and destinations where card acceptance is limited. The recommended approach for most trips is a fee-free card as the primary spending method, supplemented by a modest cash float for card-free situations.
Should I order travel money before I leave the UK?
Yes, if you intend to use cash. Ordering foreign currency online from the Post Office, Tesco Travel Money, or a specialist online bureau before departure, and collecting it in-store or having it delivered, consistently produces better rates than exchanging at the airport or on arrival. For card users with fee-free digital cards, no advance preparation is required as the conversion happens at the point of transaction at the prevailing mid-market rate.
What is Dynamic Currency Conversion and should I avoid it?
Dynamic Currency Conversion (DCC) is an option offered by foreign payment terminals and ATMs that converts your transaction to sterling before charging your UK card. It should always be declined. DCC rates are set by the merchant or ATM operator and consistently include a markup of 3% to 10% above the mid-market rate, producing a significantly worse outcome than allowing your card's own conversion process to apply. Always choose to pay in the local currency when prompted at a foreign terminal or ATM.
Are prepaid travel cards worth it for UK travellers?
Prepaid travel cards are worth considering for travellers who want to lock in an exchange rate in advance or who prefer the security of a card not connected to their main bank account. However, the exchange rates available at loading are typically not as competitive as those from fee-free digital cards like Wise or Revolut. For travellers comfortable with a digital banking app, a fee-free multi-currency card generally offers a lower all-in cost than a standard prepaid travel card for most destinations.
