Since 2015, digital-first banking has transformed the experience of managing money across borders. For British expats, digital nomads, and internationally mobile HNW individuals, the arrival of Wise (formerly TransferWise), Revolut, and Monzo meant an end to the era of paying 3–4% foreign exchange margins to high-street banks on international transfers.
But these three apps are not equivalent. Each has a different regulatory model, a different primary use case, and a different relationship with the kind of client who holds meaningful balances and transacts internationally. This guide gives you an honest comparison.
Wise: the international transfer specialist
Regulatory status: FCA-authorised payment institution (not a bank). E-money licences in the EU, Singapore, Australia, Canada, and the US. Client funds are ring-fenced and segregated from Wise's own operating funds, but they are not FSCS-protected in the way that bank deposits are.
What Wise is genuinely excellent at: international money transfers at the mid-market exchange rate, plus a transparent fee (typically 0.41–1.8% depending on the currency pair and amount). For most currency corridors, this significantly undercuts the effective rate that high-street banks offer when you add up their stated fee plus their exchange rate margin. Wise's published fee structure is genuinely transparent in a way that legacy banking is not.
The multi-currency account: Wise offers a personal and business multi-currency account with local account details in approximately 10 currencies (GBP, EUR, USD, AED, AUD, SGD, THB, and others). This means you can receive USD to a real US account number and sort code, EUR to a real IBAN, GBP to a real UK sort code — without a bank in each country. For freelancers and business owners with clients across multiple jurisdictions, this is genuinely useful.
The Wise debit card works in any currency, converting at the mid-market rate when you spend. It is widely accepted and works at ATMs globally (typically two free ATM withdrawals per month up to a limit, then a small fee).
The limitations: Wise is not a bank. It does not offer credit (no overdraft, no credit card). Customer service is limited to chat and email — there is no branch or phone banking. Because Wise is not a deposit-taker, balances are not FSCS-protected at all; the ring-fencing (safeguarding) of client funds is meaningful but not equivalent to FSCS deposit protection. Wise is best for managing international money flows rather than as the primary home for significant wealth.
Revolut: the feature-rich international account
Regulatory status: Revolut holds a UK banking licence granted by the PRA in July 2024, giving FSCS protection up to £120,000 (the limit since 1 December 2025) for eligible UK banking customers. In the EU, Revolut Bank UAB is a licensed bank in Lithuania, passporting services across the EEA.
What Revolut is excellent at: multi-currency spending, international transfers (free between Revolut users; competitive rates for external transfers), and an extensive ecosystem of additional features — cryptocurrency trading, stock trading, travel insurance, and airport lounge access at premium tiers.
The tier structure: Revolut Standard (free), Plus, Premium (around £10/month), Metal (around £15/month). The paid tiers unlock benefits including higher ATM withdrawal limits, better FX rates (Standard tier applies a weekend FX surcharge; higher tiers do not), travel and purchase insurance, and concierge services.
The currency conversion: Revolut converts at the interbank rate during weekday market hours (a significant saving versus high-street banks). On weekends, when currency markets are closed, a small markup applies. Premium and Metal tier customers get interbank rates seven days a week. For an internationally mobile client spending regularly in multiple currencies, the premium tier fee is usually recovered quickly in savings on currency conversion.
The banking licence: the 2024 UK banking licence is a significant development. FSCS protection means that up to £120,000 per customer (the limit since 1 December 2025) is protected in the same way as with any high-street bank. Previously, Revolut operated as an e-money institution and FSCS protection was not available. New UK banking customers benefit from this protection; legacy e-money customers were being migrated to the banking product.
The limitations: Revolut has had a complex regulatory journey, and its customer service reputation has historically been mixed. The sheer breadth of features (crypto, stocks, insurance, banking) means the core banking offering competes for attention with financial products of variable suitability. HNW clients should be selective about which Revolut features they use.
Monzo: the best UK current account
Regulatory status: Monzo is a fully licensed UK bank (PRA-authorised), with FSCS protection up to £120,000 (the limit since 1 December 2025). It has been a licensed bank since 2017.
What Monzo is excellent at: Monzo is arguably the best-designed UK current account available. Its budgeting features, instant notifications, pot segregation, and overall user experience are outstanding for day-to-day UK banking. Bill splitting, round-ups, salary advance features, and integration with UK financial systems (CHAPS, Faster Payments, Direct Debit) work seamlessly.
The limitation for expats: Monzo is a UK bank, built primarily for people living in the UK. While the Monzo debit card works globally, it does not offer a multi-currency account, local account details in non-UK currencies, or the international transfer efficiency of Wise or Revolut. If you are living outside the UK full-time, Monzo is not designed for your banking situation.
Best use case for internationally mobile clients: maintaining a UK current account when you retain UK financial obligations (receiving UK pension or rental income, paying UK tax, maintaining a UK direct debit history).

The recommended stack for expats
Most internationally mobile HNW clients benefit from using multiple apps in combination rather than relying on any single one:
For international transfers and multi-currency income collection: Wise. Use the Wise multi-currency account as the hub for receiving international income in different currencies and making overseas payments efficiently.
For international spending card and investment features: Revolut Premium or Metal. The interbank FX rates, travel insurance, and investment features make the monthly fee worthwhile for active international travellers.
For UK-based day-to-day banking: Monzo or a traditional UK bank. If you retain UK financial obligations, keep a UK bank account (Monzo, or a mainstream bank account) for legacy payments, electoral roll registration continuity, and mortgage/credit history maintenance.
For large balances: none of the above. Significant wealth should be held in traditional banks or private banks with full regulatory protection, investment diversification, and relationship management. Use fintech apps as efficient transaction rails, not as custodians of meaningful wealth.
The HNW client perspective
For clients with £500,000 or more in liquid assets, challenger banks are useful tools but not primary wealth custodians. The FX and transfer efficiency they offer should be seen as operational infrastructure — ways to move money efficiently between a primary private bank account and international counterparties.
The lack of credit facilities, limited customer service, and (in Wise's case) the absence of FSCS protection mean that these platforms are not substitutes for a proper private banking relationship. They are, however, excellent complements to it.
