Cheapest International Money Transfers 2026: 8 Services Compared

Last updated: April 2026

International money transfers are one of those things where the price you see is almost never the price you pay. Banks advertise "free transfers" while hiding a 3% markup in the exchange rate. Fintech apps show you a low fee but the rate moves by the time you confirm. We wanted to cut through the noise.

So here is what we always do at BankTopp: we cut through it. This guide sets out eight different services across five corridors from the UK, based on each provider's published fees and exchange-rate terms at the time of writing — the fee, the exchange rate applied, how much actually reaches the destination currency, and how long it takes. This is a desk-based comparison of published terms, not a live test of real transfers, so always check the current rate before you send.

The Services We Compared

We compared the eight services most commonly recommended for international transfers:

1. Wise

2. Revolut (Standard plan)

3. Airwallex

4. OFX

5. WorldRemit

6. Western Union

7. PayPal

8. A traditional UK high-street bank (HSBC)

We looked at five corridors from the UK: Poland (PLN), the United States (USD), Norway (NOK), Thailand (THB), and Australia (AUD).

How the Services Compare

GBP to USD (United States)

For major currencies like USD, Wise, Revolut, and Airwallex all land very close to the mid-market rate with low, transparent fees. Within its monthly free-exchange allowance, Revolut is typically the cheapest, with Wise and Airwallex a hair behind. A traditional bank like HSBC applies a markup of roughly 2-3%, which makes it materially more expensive on the same transfer.

Cheapest: Revolut (within its free tier), with Wise and Airwallex extremely close. Traditional banks are consistently the most expensive.

GBP to PLN (Poland)

Wise and Revolut both stay close to the mid-market rate for PLN. PayPal and Western Union tend to add both a fee and a percentage markup, which makes them noticeably more expensive.

Cheapest: Wise or Revolut, with PayPal typically the most expensive by a significant margin.

GBP to NOK (Norway)

For GBP to NOK, the fintech options (Wise, Revolut, Airwallex) cluster together near the mid-market rate and are usually within a small margin of each other. Any of the three is a strong choice; a traditional bank is not.

Cheapest: any of the fintech options, which are typically within a couple of pounds of each other.

GBP to THB (Thailand)

Exotic currencies are where the differences get real. Wise tends to hold close to the mid-market rate here, while Revolut can apply a markup on exotic currencies (even mid-week). Money-transfer specialists like WorldRemit are competitive, and traditional banks are the most expensive.

Cheapest: Wise, by a meaningful margin, because it does not apply the exotic-currency markup that Revolut adds.

GBP to AUD (Australia)

For AUD, Wise and Revolut are again very close, and OFX is competitive for larger amounts as it often waives the transfer fee above a threshold.

Cheapest: Wise or Revolut, with OFX worth checking on larger transfers.

Summary

Across major corridors (USD, PLN, NOK, AUD), Revolut's free tier and Wise are neck-and-neck — the difference is usually small. For exotic currencies like THB, Wise consistently performs better because it does not add the markup Revolut applies. Airwallex is competitive in every corridor and would be our pick for business transfers. OFX and WorldRemit are mid-range, while PayPal and traditional banks are consistently the most expensive options.

Speed: How Long Do Transfers Take

Wise and Revolut typically deliver funds for major currencies within hours, sometimes minutes. Exotic-currency transfers can take up to a day. Traditional bank transfers usually take one to three business days. This speed advantage alone is worth switching for.

Hidden Fees to Watch For

The biggest hidden cost in international transfers is the exchange rate markup. A service can advertise zero fees while giving you a rate that is 2-3% worse than the mid-market rate. On a £500 transfer, a 3% markup costs you £15 — more than any explicit fee.

Always compare the amount that will actually arrive, not just the advertised fee. Wise is the most transparent here — they show you the fee and the mid-market rate separately, so you always know what you are paying.

Another hidden cost is the receiving bank's fee. Some banks charge the recipient to receive an international transfer. This is outside the sender's control, but it is worth checking with the recipient's bank.

Our Recommendation

For regular international transfers in major currencies (USD, EUR, GBP, NOK, PLN, AUD), Revolut's free tier is hard to beat — provided you stay within the monthly limit. For exotic currencies, larger transfers, or if you want maximum transparency, Wise is the better choice.

For business transfers, Airwallex offers the best combination of rates, speed, and features. We cover business use cases in our best business bank accounts guide. And for a broader comparison of Revolut and Wise beyond just transfers, see our detailed Revolut vs Wise analysis.

If you are still using a traditional bank for international transfers, you are almost certainly overpaying. The switch to any fintech service on this list will save you money on every single transfer.
