Currency & Money Abroad — Complete Guide for UK Travellers 2026

The single best financial decision for most UK travellers is to get a fee-free travel debit or credit card before you go. These cards use the real exchange rate (the interbank rate — the same rate banks use between themselves) and charge no foreign transaction fees. The difference versus using a standard UK debit card abroad can be 3–5% per transaction.

These are the fees that cost UK travellers the most money every year:

• Foreign transaction fee (2.99%): Most standard UK bank cards add a 2.99% fee on every transaction abroad — this applies to both purchases and ATM withdrawals
• Non-sterling transaction fee: Different name, same thing — adds 1.5–3% to every purchase
• ATM withdrawal fee: Many UK banks charge £1.50–£3 for every foreign ATM withdrawal, on top of the exchange rate fee
• Airport exchange desk: Rates at airport bureaux de change are typically 10–15% worse than the mid-market rate — the worst place to buy currency
• Hotel exchange: Usually almost as bad as the airport — only use in genuine emergency
• Credit card cash advance abroad: Most credit cards treat foreign ATM withdrawals as cash advances — high interest from the moment of withdrawal plus a fee. Use a debit-based travel card for ATM withdrawals.

The cashless revolution has reached most of the world's popular tourist destinations, but cash remains essential in many situations:

When You Need Cash

• Markets, street food vendors and small local restaurants in developing countries
• Taxis (many won't accept cards, especially outside cities)
• Tips — hotel staff, tour guides, safari guides, spa workers
• Entrance fees at local attractions in less-developed destinations
• Emergency backup if your card is blocked or stolen

Where Card is Fine (or Better)

• Restaurants, hotels and shops in Europe, USA, UAE and most developed destinations
• Supermarkets and chain stores worldwide
• Any purchase where you'd prefer a paper trail for insurance purposes

Recommended strategy: Carry 2–3 days' worth of local currency in cash at all times, supplemented by a travel debit card for larger purchases. Keep cash and cards in separate locations (one set in your wallet, backup hidden elsewhere) in case of theft.

1. Use your travel money card (Wise, Starling, Revolut) — not your standard UK bank card — to avoid foreign transaction fees
2. Always withdraw in local currency — if an ATM asks "Do you want to be charged in GBP or [local currency]?" always choose local currency. Choosing GBP triggers Dynamic Currency Conversion (see below) which gives you a terrible rate
3. Use bank ATMs, not standalone ATMs — standalone ATMs at tourist attractions, airports and nightclubs often charge additional operator fees of £3–£5 per withdrawal. Use ATMs attached to actual bank branches where possible
4. Withdraw a reasonable amount each time — multiple small withdrawals mean multiple sets of any per-transaction fees. Better to withdraw enough for 3–4 days at once
5. Keep your ATM receipts — useful for tracking spending and as evidence if a transaction dispute arises

Ranked from best to worst exchange rates:

1. 🥇 Travel money card (Wise/Starling/Revolut) — mid-market rate, no commission
2. 🥈 Local ATM in destination country — using travel card; local rate, small fee
3. 🥉 Online travel money (Sainsbury's, Post Office, Moneycorp) — order online, collect or home delivery. Significantly better than airport rates
4. High street travel money bureau — M&S, Post Office, Travelex high street — decent rates if ordered in advance, poor if buying on the day
5. Travelex airport (landside) — poor rates, sometimes 8–10% below mid-market
6. ❌ Airport arrival hall bureau de change — the worst rates in the world, avoid at all costs
7. ❌ Hotel exchange desk — almost as bad as airports

The Post Office Travel Money app is worth using if you prefer to pre-load a card or order cash online — rates are significantly better than anything at the airport.

Dynamic Currency Conversion (DCC) is a service offered by card terminals and ATMs abroad that lets you pay in GBP instead of the local currency. It sounds convenient — but it's a trap. The exchange rate applied is typically 5–12% worse than the mid-market rate, meaning you'll always pay significantly more than if you'd paid in local currency.

When a card terminal asks: "Do you want to pay in GBP or Thai Baht (or Euros, Dirhams, etc.)?" — always choose the local currency.

The same applies at ATMs: if asked whether you want to be "charged in GBP" — select "No" or "Decline" and choose to be charged in local currency. The ATM or terminal provider profits from the DCC commission; your bank's rate (especially on a travel card) will be significantly better.
