Here is a scene that plays out at Heathrow Airport approximately one thousand times a day.
A traveller arrives from Africa, walks up to the Travelex counter in the arrivals hall, and exchanges their dollars or rands or kwacha for British pounds. They notice the rate seems a bit low but it's late, they're tired, and they just want to get in a taxi. They hand over $500 and walk away with less than they should have received.
How much less? Travelex airport exchange rates are typically 10–15% below the mid-market rate. On a $500 exchange, that is $50–75 gone at the first hurdle, before you have even bought a coffee.
This guide is about not being that person. Not because airport money changers are evil — they're a business — but because in 2025, there are much better options available to anyone travelling from Africa to Europe or the UK.
The real cost comparison: spending £1,000 on a trip to the UK
Let's use a concrete example. You are travelling from Zimbabwe (spending USD) or South Africa (spending ZAR) to the UK for two weeks. You plan to spend approximately £1,000 equivalent. Here is what different methods actually cost you:
| Method | Exchange rate vs mid-market | Fees | Effective cost of £1,000 |
|---|---|---|---|
| Wise card | Mid-market rate | ~0.4–0.7% conversion | ~$1,270 (ZAR equivalent: ~R23,650) |
| Revolut (standard) | Mid-market Mon–Fri | Free up to limit, 0.5% weekend | ~$1,275 |
| FNB Global Account (South Africa) | 2–3% below mid-market | R40 monthly fee | ~R24,800 |
| Standard Bank travel card (South Africa) | 2–4% below | Loading fee applies | ~R25,100 |
| Airport Travelex / bureau | 10–15% below | None, but rate absorbs profit | ~R27,000+ |
| Your home bank debit card abroad | 3–5% below + international fees | £2–5 per transaction + 3% foreign fee | ~R27,500+ |
Using your regular home bank debit card abroad is the most expensive option of all — worse than the airport bureau for extended spending because the per-transaction fees compound quickly.
The call your bank will make
Before we get into card recommendations, you need to know about this. It happens to almost every African traveller to Europe for the first time.
You land. You try to pay for something. Your card declines. You try again. Declined. You call your bank in a mild panic, get through after 15 minutes on hold, and are told your card was "blocked for suspicious activity."
Your bank saw a transaction in London and thought you were being defrauded.
This is genuinely well-intentioned and genuinely infuriating. The fix: call your bank before you travel and tell them your travel dates and destination countries. Most African banks have a "travel notification" option — use it. Do this at least a week before departure because some banks need time to update your profile.
Alternatively — and this is the better long-term solution — use a travel card that is designed for international use and does not block international transactions.
Wise Travel Card — the best overall option
The Wise card is the one I recommend most consistently, and the reason is simple: it uses the mid-market exchange rate with transparent, low fees.
How it works:
- Order the card from wise.com (available to customers in Zimbabwe, South Africa, Nigeria, Ghana, Kenya, and most other African countries)
- Load money from your local bank account in your local currency
- Spend in GBP, EUR, or any other currency — Wise converts at the mid-market rate
Fees to know:
- Sending money to the card: small fee depending on your country and currency (typically 0.5–1%)
- ATM withdrawals: 2 free withdrawals per month (up to £200 total free per month, then 1.75% + £0.5 per withdrawal)
- Weekend transactions: same rate as weekdays (unlike Revolut)
- Card order fee: varies by country, usually $5–10 equivalent
The practical reality: The Wise card is genuinely what I use when travelling. It has never been blocked at a European terminal. It works at UK supermarkets, on the London Underground, at restaurants, everywhere a Mastercard is accepted.
Revolut — excellent but with one catch
Revolut is arguably the slickest travel money app available and its rates are excellent — when the market is open. The catch: on weekends, Revolut applies a 0.5% markup on currency conversion because the forex markets are closed. For a 2-week trip that includes two weekends, this is worth being aware of but is not a deal-breaker.
The bigger practical issue for African travellers: Revolut's availability varies significantly by country. It is fully available for South Africans. For Zimbabweans and some other nationalities, opening a full account can be harder depending on your country of residence. Check current availability at revolut.com for your specific country.
Where Revolut wins: the app is beautiful. Spending analytics, instant notifications, budgeting tools, and the ability to hold 30+ currencies simultaneously are genuinely useful for frequent travellers.
FNB Global Account (South Africa)
For South African travellers, FNB's Global Account is a solid option from a bank you probably already use. It comes with a Visa card that works internationally and uses a rate that — while not as good as Wise — is meaningfully better than your standard FNB debit card used abroad.
Best for: South Africans who want to stay within their existing banking relationship and not open a new account with an unfamiliar provider.
Limitation: The exchange rate is 2–3% below mid-market, which adds up on a longer trip. If you are spending more than R10,000 equivalent, the Wise card will save you meaningfully more.
Case study: Simba's two-week UK trip
Simba is a 35-year-old consultant from Harare who visited London for two weeks for a professional development course. He spent approximately $1,400 equivalent during the trip — accommodation, food, transport, and shopping.
He had done no preparation. He used his Zimbabwean bank Visa debit card throughout the trip.
Post-trip analysis:
- Average foreign transaction fee: 3.5% per transaction
- International ATM withdrawal fees: $5 per withdrawal, 8 withdrawals = $40
- Exchange rate margin below mid-market: approximately 4.5%
- Total extra cost vs using Wise card: approximately $130
On his next trip, Simba set up a Wise account three weeks before departure. He loaded $1,500 onto the card. The conversion fee was approximately $9. He saved over $120 compared to his previous trip — which paid for two very good dinners in London.
He also did not experience a single card block.
Cash: how much, where to get it
Some situations in the UK and Europe still require cash — smaller markets, some rural accommodation, certain transport. But not nearly as much as you might think. London, Paris, Amsterdam, and most major European cities are almost entirely contactless-card friendly.
A reasonable rule: keep £100–150 equivalent in local currency for genuinely cash-only situations. Get it from an ATM using your Wise or Revolut card, not from an airport bureau.
ATM tips:
- Always choose to be charged in the local currency (GBP or EUR), not your home currency. The option to pay in your home currency (called Dynamic Currency Conversion) sounds convenient but uses a terrible exchange rate
- Avoid ATMs in tourist areas — they sometimes offer their own "guaranteed rate" which is also terrible
- Monzo, Starling, Wise, and Revolut all have ATM locators in their apps
The checklist before you travel
- ✅ Order your Wise card at least 2 weeks before travel (delivery takes time in some countries)
- ✅ Call your home bank to notify them of your travel dates
- ✅ Load your Wise or Revolut card with your budget before departure (avoid loading at the airport)
- ✅ Save Wise and Revolut customer service numbers in your phone
- ✅ Have a backup card in a separate location from your primary card
- ✅ Never exchange currency at airport bureaux unless it is a genuine emergency
