Guide to International Money Transfers for UK Businesses

A supplier invoice arrives in euros, due in fourteen days, and the only figure on your bank’s confirmation screen is a £12 transfer fee. That £12 isn’t the cost of the payment. The bigger number sits in the exchange rate, and your bank won’t show it to you as a separate line: a business sending a £20,000 supplier invoice at a 3% FX margin pays £600 more than one using a mid-market provider, before any transfer fee is counted at all.

So there are two costs here, not one, and only one of them is advertised. When you pay an overseas supplier, the only reliable way to judge value is to compare what actually lands in their account. We checked the regulatory facts in this guide against the Financial Conduct Authority (FCA) and the Financial Services Compensation Scheme (FSCS), and we took provider details from provider-published information in August 2026.

Step-by-Step: How an International Money Transfer Works

Every international transfer moves through the same five stages, whether you use a bank or a specialist provider. Knowing which stage a payment has reached is what lets you answer the supplier who emails on day four asking where the money is, so we trace all five below and name the point at which each one tends to stall.

1. Setting Up the Transfer

You specify the send amount, the send currency, the receive currency, and the beneficiary. You’ll need the recipient’s legal name, bank details, a payment reference, and in some cases a payment purpose or invoice number. The provider quotes an exchange rate and any fees before you confirm the instruction, and the funding method you choose (bank transfer, debit card, or a pre-funded balance) affects both the fee and how quickly the first leg of the payment moves.

2. Compliance and Payment Checks

Before any money moves, the provider runs anti-money laundering and sanctions screening on the payment and on the beneficiary. For a first-time recipient, a large payment, or an unusual pattern, the provider may ask for supporting documents: an invoice, a source-of-funds explanation, or information about the business relationship.

These checks add time, particularly where the provider has to come back to you before releasing the funds. The awkward case is a first payment to a new supplier at month-end: the compliance queue and your payment deadline don’t know about each other. Build review time into your planning for anything large or first-time.

3. Currency Conversion and Exchange Rates

When you send pounds and the recipient expects a different currency, the provider converts the funds at the rate it has quoted you. The reference point for any conversion is the mid-market rate: the midpoint between the global buy and sell prices for a currency pair at a given moment.

Your provider’s customer rate will differ from the mid-market rate by whatever margin the provider adds. The moment of conversion also varies: some providers convert when you instruct the payment, others when the funds arrive at the next stage. On a volatile morning that gap is the difference between the rate you were quoted and the rate you actually paid, so it’s worth asking which model your provider uses before you send anything large.

4. Routing the Payment

The converted funds are sent to the recipient’s bank via one of several possible routes. The route depends on the provider, the currency corridor, and whether the sending and receiving banks have a direct relationship. The main options are the Society for Worldwide Interbank Financial Telecommunication (SWIFT) network, the Single Euro Payments Area (SEPA) for euro-denominated payments across participating countries, and local domestic payment systems for providers that hold accounts in multiple countries. The route chosen affects both the cost and the speed of this stage.

5. Settlement and Recipient Credit

Settlement is the process by which the receiving bank confirms it has the funds and credits them to the beneficiary’s account. Arrival at the receiving institution and credit to the account are not the same event. The gap between them is where most of the confusion in a late payment lives. The receiving bank may run its own processing and compliance checks before the money shows up in the recipient’s account.

The payment lifecycle is only complete when the recipient has usable funds, not when the sending provider marks the instruction as sent.

What Happens Behind the Scenes

The route your payment takes decides most of what it costs and how long it sits in transit, and you rarely get to pick it. Three mechanisms do the carrying: SWIFT and correspondent banking, SEPA for euro payments, and the local payment systems some specialist providers hold accounts in. When you send the same euro invoice payment two different ways, one can be credited to your supplier the next morning while the other is still working through a correspondent bank in a third country.

SWIFT and Correspondent Banking

SWIFT is primarily a secure financial messaging network, not the mechanism that physically moves money. We confirmed the network figures from the August 2026 SWIFT publication: 11,500+ institutions across 200 countries and territories. Each sends encrypted payment instructions to the others. When your bank sends an international wire, it sends a SWIFT message instructing the receiving bank to credit your recipient’s account.

Where two banks don’t hold accounts with each other directly, one or more correspondent banks step in to bridge the gap. Each correspondent holds accounts on behalf of other banks and processes the payment leg by leg. The Bank of England describes this as the standard structure for cross-border payments where no direct banking relationship exists between sending and receiving institutions.

A SWIFT message moves at the speed of a message. The money moves at the speed of the slowest bank in the chain, and those aren’t the same thing. The time from your payment instruction to credit in the recipient’s account depends on correspondent bank processing, compliance checks, banking cut-off times, and the receiving bank’s own procedures, so the full journey varies widely by corridor. It’s why we don’t quote a standard SWIFT transfer time anywhere on this page.

Each correspondent bank in the chain may also deduct a handling charge, and how much depends on the route, the currency, and the charging instruction you apply.

SEPA and European Payments

SEPA standardises euro-denominated bank transfers across participating European countries. A SEPA Credit Transfer uses an International Bank Account Number (IBAN) and a Bank Identifier Code (BIC) to route a euro payment between participating accounts, typically settling the next business day. SEPA Instant can credit your recipient within seconds where both banks support the service.

Since the UK left the European Union, your business isn’t a domestic SEPA participant. Some specialist providers can still route euro payments through SEPA infrastructure using their European entities. Where that isn’t available, your payment travels via SWIFT or a local account arrangement instead.

Local Payment Systems

On supported currency corridors, some specialist providers use a different model. They receive your funds locally in pounds, convert the currency, and pay the recipient through a domestic payment system in the destination country. This reduces reliance on correspondent banking and SWIFT for parts of the payment journey, and can mean faster delivery and more predictable costs on those routes.

This model works well for major currency pairs and high-volume corridors, but it needs the provider to hold pre-funded accounts at both ends, so coverage varies by provider and by corridor. Ask which of your corridors are actually covered: the ones that aren’t drop back to SWIFT, and you’ll see the difference in the timing.

What Details Do UK Businesses Need to Send Money Abroad?

Recipient and Business Information

Get one field wrong and the payment doesn’t come back politely: it sits somewhere in the chain, and when your supplier emails to ask where the money is, all you have is a confirmation screen saying sent and no idea where it stopped. Recalls cost money and take days. We’ve set out the full checklist below; most providers want every item on it.

• Beneficiary legal name exactly as it appears on the recipient’s bank account.
• Recipient address, required by some corridors and compliance frameworks.
• Beneficiary bank name and address.
• Account identifier: IBAN for European and many international accounts, or a local account number for countries that do not use IBAN.
• Bank identifier: BIC or SWIFT code for the receiving bank.
• Local routing code where required: ABA routing number for US dollar payments, BSB for Australia, IFSC for India.
• Payment currency in which the recipient expects to be paid.
• Payment reference so the recipient can match the funds to an invoice.
• Payment purpose, required in some jurisdictions and by some compliance frameworks.
• Supporting documentation such as an invoice or contract, if the provider or the destination country requires it.

IBANs, BICs and SWIFT Codes

An IBAN is a standardised number that identifies one specific bank account across international payment systems: country code, check digits, and the account number. European bank accounts use IBANs as standard and many other countries have adopted the format. A BIC, also called a SWIFT code, identifies the bank and branch holding that account, and the two together give the payment network enough to send the money to the right place. A missing BIC is a reason to pause and confirm with the recipient, not to send and hope.

US Routing Numbers and Other Local Bank Codes

Not every country uses the IBAN system. Sending to a US dollar account typically needs the ABA routing number alongside the account number, and some corridors also want a purpose-of-payment code, a beneficiary address, or extra regulatory information before the payment will process. Your provider should confirm what your specific destination needs; where there’s any doubt, ask the recipient to check with their own bank, because a phone call at their end is cheaper than a returned payment at yours.

Payment References and Supporting Information

A clear payment reference is what stops your supplier applying the money to the wrong invoice. It matters most on regular supplier payments, where several amounts land in the same week and nothing else tells the recipient which is which. Keep a record of the rate quoted, the fee paid, and the payment confirmation, so you can reconcile the transaction once it’s credited.

How UK Businesses Use International Money Transfers

Paying Overseas Suppliers

Paying a supplier in another country is the most common reason UK businesses make international transfers. The key decisions are which currency to pay in, how to confirm the amount the supplier will receive, and which charging arrangement to use for correspondent bank fees.

We rate one habit above the rest here: confirm with the supplier what amount they expect to receive, not just what you intend to send. That single question heads off most disputes, because a credited amount can fall short through intermediary deductions or a conversion at the receiving end. For a more detailed workflow, see our guide to international business money transfers.

Paying Contractors and International Payroll

Paying several recipients in different countries adds complexity fast. Each one may need a different currency, a different payment route, and a fixed date. Providers with batch payment capability and reusable beneficiary records cut the manual work down, which is the difference between one approval and fifteen. For international payroll we recommend checking when conversion happens and which rate applies on each pay date: if your payroll run converts at a different moment every month, the same gross salary lands as a different net figure, and the person receiving it notices.

Receiving International Payments

Receiving money from overseas customers involves its own set of decisions. If the customer pays in their local currency, the conversion to pounds happens at your bank or at the receiving account you provide. We cover multi-currency receiving accounts in our guide to international business money transfers; giving customers a local currency account can reduce conversion costs and make it easier for them to pay in the currency they hold.

Sending Large or One-Off Transfers

Larger transfers and one-off payments such as property purchases need specialist handling. On a £250,000 payment, a 1% move in the rate is £2,500, so timing stops being a detail and starts being the cost. Transfer limits become relevant at that size, compliance due diligence is more thorough, and specialist FX providers typically offer dedicated dealer support and currency risk tools, including forward contracts.

What International Money Transfers Cost

The Exchange Rate Margin

The FX margin is the difference between the mid-market exchange rate and the rate your provider quotes you. Banks and some providers bundle that margin into the rate and don’t itemise it at all. A zero-fee transfer isn’t a free transfer: the provider advertising “fee-free” is usually applying a wider margin instead, which moves the cost out of the fee line and into the exchange rate, where you can’t see it.

You can look the mid-market rate up yourself on a currency data service such as xe.com. It’s the wholesale interbank rate financial institutions use between themselves, and your provider’s rate will be less favourable by whatever margin it applies. On anything above a few thousand pounds, we find the margin rather than the fee is the larger of the two costs.

Transfer Fees

Fees are the visible half of the cost. Banks typically charge a fixed wire fee for outbound international transfers; specialist providers often charge a percentage of the amount, a flat fee, or a combination, and the structure varies by provider, corridor, and transfer size. Volume decides whether the fee matters much at all. At 20 transfers a month, a £15 flat wire fee costs you £3,600 a year, and at that frequency it stops being the small number.

Intermediary and Receiving-Bank Charges

When a payment travels through one or more correspondent banks, each institution in the chain may deduct a handling charge before passing the funds on. The amount, and whether any deduction occurs at all, depends on the specific route, the banks involved, the currency, and the charging instruction applied to the payment.

The charging instruction determines who pays these costs. With an OUR instruction the sender agrees to cover applicable transfer charges, which reduces the risk of the recipient getting less than expected; it doesn’t remove it. Confirm the route and how the receiving bank treats incoming payments rather than treating OUR as a guarantee. With a SHA (shared) instruction the charges are split, and your recipient may well be credited less than the gross amount you sent.

How to Compare the Amount the Recipient Receives

The only honest way to compare providers is to enter the same send amount, the same currency pair, and the same funding method into each provider at the same time, then compare the amount the recipient will receive. This single number captures the FX margin and the explicit fees together. A lower headline fee doesn’t help you if the exchange rate behind it is worse by more than the fee you saved.

When you ask for quotes, record the exchange rate, the fee, any other disclosed charges, and the recipient amount. Note the time of the quote too, because FX rates move while you’re reading them. We judge providers on the recipient amount and never on the advertised fee: it’s the only figure that says what the transfer actually cost you.

How Long International Transfers Take

Typical Timelines by Payment Route

There is no single answer to how long an international transfer takes, because the timeline depends on the payment route, the currency corridor, the provider, and the receiving bank. Below we give indicative ranges for common routes, not guaranteed times.

• Local payment rails (major corridors): Same day to a few hours. Depends on provider coverage and the receiving bank’s procedures.
• SEPA Instant: Seconds to minutes. Both banks must support SEPA Instant; not available on all UK-originating payments from all providers.
• SEPA Credit Transfer: Typically 1 business day for eligible euro payments across participating countries.
• SWIFT via correspondent banking: Varies significantly by corridor and provider. SWIFT messages can travel quickly between institutions, but the full credit process, including correspondent bank processing, compliance checks, and receiving-bank procedures, can take considerably longer.

Cut-Off Times, Weekends and Bank Holidays

Every bank and payment provider operates cut-off times for same-day processing. A payment instructed after the cut-off will be queued until the next processing window, which on a Friday afternoon can mean a wait until Monday. Bank holidays in both the sending and receiving country affect timing. A payment from the UK to the US that falls on a US federal holiday will sit at the receiving institution until the next working day. We recommend checking the cut-off before you send anything time-sensitive, and month-end supplier payments in particular.

Why a Transfer Can Take Longer Than Expected

Route and cut-off times explain the ordinary cases. The delays that catch you out come from things happening out of your sight, and you usually only find out about them by asking.

• Incorrect beneficiary details. A mismatched name, account number, or IBAN can cause a payment to be returned or placed on hold.
• Compliance review. Large, unusual, or first-time payments may be reviewed before release. The provider may contact you for supporting documentation.
• Sanctions screening. Payments involving certain entities or countries are subject to additional checks and may be delayed or stopped.
• Correspondent bank processing. Each bank in a SWIFT chain processes payments in its own time. A delay at any point adds to the total journey time.
• Receiving bank processing. Even after funds arrive at the beneficiary bank, internal crediting procedures can delay when they appear in the account.
• Destination-specific requirements. Some countries require payment purpose codes, additional compliance documents, or local bank approval before funds can be credited.

How Destination Country Affects Your Transfer

The identifier your recipient needs depends on where they bank, and there’s no universal format. An IBAN gets you into a Eurozone account and is no use at all in the United States. We cover the most common corridors below.

Sending Pounds to the Eurozone

When you send to a Eurozone account you’ll typically need the recipient’s IBAN and BIC. Paying in euros rather than pounds avoids a second conversion at the receiving bank, at a rate you never see and never agreed to. Some specialist providers can route euro payments through SEPA infrastructure via their European entities, which on these corridors is usually faster and cheaper than a full SWIFT wire.

Sending Money to the United States

US dollar payments to American accounts need an ABA routing number alongside the account number; the IBAN system isn’t used in the United States. Payments to the US typically travel via SWIFT and may pass through one or more correspondent banks, particularly where the sending and receiving institutions don’t have a direct banking relationship. That chain is where the deductions happen, so on a US invoice it pays to agree the charging instruction with your supplier up front.

Other Destination Requirements

Different countries impose different requirements before a payment can be credited. Australia uses BSB codes alongside account numbers. India requires an IFSC code for domestic bank routing. Some jurisdictions require a purpose-of-payment code, a beneficiary address, or a copy of the underlying contract before the receiving bank releases the funds.

Your provider should be able to confirm what is required for your specific destination. We recommend verifying requirements before you send; getting the details wrong triggers recalls, delays, and additional fees.

Is Your Money Protected?

The answer depends on who you send with, and the three categories aren’t close to equivalent. A bank, an authorised payment institution, and a small payment institution offer you three different things, and only one of them is FSCS deposit protection. We weighed all three against the same question: if the firm fails, what comes back to you, and how long do you wait for it?

UK Banks and FSCS Protection

If you send an international payment through a UK-authorised bank, eligible deposits in your account are covered by the FSCS up to the point of sending. The current standard deposit protection limit is £120,000 per eligible person, per authorised firm, effective from 1 December 2025 (source: FSCS). FSCS protection covers your deposit balance at the bank, not an in-transit payment instruction.

Authorised Payment Institutions and Electronic Money Institutions

Specialist transfer providers operate as FCA-authorised payment institutions (PIs) or electronic money institutions (EMIs), not as banks. Funds held with these firms aren’t covered by the FSCS. Instead, authorised PIs and EMIs are required by law to safeguard relevant customer funds: your money is segregated from the firm’s own capital, ring-fenced at a separate institution or in qualifying assets, and can’t be lent out.

Safeguarding is distinct from FSCS deposit protection. If an authorised PI or EMI fails, the safeguarded pool is used to repay customers. We rate the framework as real protection rather than a marketing line, but it isn’t quick money: the insolvency process can be lengthy, and administration costs may reduce what finally comes back to you.

From 7 May 2026, the FCA’s PS25/12 rules strengthened safeguarding requirements: authorised firms must now reconcile customer funds daily, certain firms must commission an annual safeguarding audit, and all must maintain a resolution pack to speed the return of funds in the event of failure (source: FCA, PS25/12, May 2026).

Small Payment Institutions

Not every regulated payment firm carries the same safeguarding obligations. Small payment institutions (SPIs) are registered with the FCA rather than fully authorised, and they aren’t generally subject to the same statutory safeguarding requirement that applies to authorised PIs and EMIs. That matters most if you hold a balance with the provider between payment runs, rather than funding each transfer and emptying the account behind it.

The protection level differs across these three categories: authorised bank, authorised PI or EMI, and small payment institution. We recommend checking the FCA Register before placing funds with any provider to confirm which category applies.

How to Check a Provider on the FCA Register

You can verify any provider’s regulatory status at register.fca.org.uk.

1. Find the provider’s legal entity name. This is usually on their website under “Legal information” or “About us”, and may differ from the trading name.
2. Search the FCA Register for that legal entity name.
3. Confirm the firm is shown as authorised (not merely registered), and note its permissions.
4. Check that the entity you are dealing with matches the one shown on the register. Some providers operate multiple legal entities.
5. Note the firm’s category: authorised bank, authorised PI, authorised EMI, or small payment institution. This determines the protection that applies.

Managing Currency Risk on Large or Future Payments

Most business payments use a spot transfer, and for most businesses we rate that as the right answer. Two other tools start to matter once you have a known bill in a foreign currency months ahead: a forward contract and a limit order.

Spot Transfers

A spot transfer converts and sends currency at the rate available when you instruct the payment. The rate is typically locked for a short settlement window. Spot transfers are the default for most business payments and work well when the payment is happening now and the amount isn’t big enough for a rate movement to cost you real money.

Forward Contracts

A forward contract allows a business to lock in an exchange rate today for a payment that will settle at a specified future date. This gives cost certainty when the business has a known future obligation in another currency, such as a supplier invoice due in three months. Specialist FX providers typically require a deposit to hold the rate.

The trade-off is clear: you’re protected if the rate moves against you, and you won’t benefit if it moves in your favour before the settlement date. A forward contract is a commitment, not an option.

When Currency-Risk Tools May Be Useful

Forward contracts and limit orders are worth the paperwork if you have fixed overseas supplier commitments priced in a foreign currency, a large one-off purchase coming, or an international payroll where the cost has to stay consistent month to month. The rule we apply is simple: the more of your margin the exchange rate can move, the stronger the case for hedging it.

What If an International Transfer Is Delayed or Does Not Arrive?

If a payment hasn’t arrived, we recommend working through the four checks below in order. Most delays resolve at step one or two.

Check the Payment Details

Confirm first that the beneficiary details you supplied are correct: the account name, the account number or IBAN, the BIC, and any local routing code. An error in any one of these fields is the most common reason a payment ends up delayed, returned, or credited to the wrong account, and it’s also the cheapest problem to find.

Check for Compliance Requests

If the provider has held the payment for review, it will usually come back to you for more information. Check whether there is a request waiting for an invoice, a source-of-funds explanation, or a description of the business relationship. These requests sometimes arrive as a secure message inside the provider’s portal rather than as an email, so look there as well as in your inbox; answering the same day is what keeps a two-day hold from becoming a two-week one.

Check Cut-Off Times and Bank Holidays

Confirm when you instructed the payment relative to the provider’s cut-off time, and check whether any bank holidays in either country fall between the instruction date and the expected arrival. Both factors can shift a same-day or next-day arrival by several working days.

Ask the Provider to Trace the Payment

If the payment appears to have been sent but hasn’t arrived, ask the provider to trace it. The key stages to confirm are: whether the instruction has been processed by the provider; whether it has been sent to the next bank; whether the beneficiary bank has confirmed receipt; and whether the beneficiary bank has credited the account.

Once your provider confirms the receiving bank holds the funds, the delay sits with the receiving institution. The recipient should then contact their bank directly with the payment confirmation reference and the sending date to help locate the funds quickly. International payments can sometimes be recalled, but the process involves both the sending and receiving banks, can take time, and isn’t guaranteed to work.

Common International Transfer Mistakes

These are the mistakes that actually cost money, and nearly all of them happen at the point of instruction, before anyone can undo them. We’ve grouped them so you can read the list as a pre-send check.

• Comparing only the headline fee and missing the FX margin, which is usually the larger cost.
• Sending in the wrong currency and allowing the receiving bank to convert at its own rate, creating double conversion costs.
• Entering incorrect beneficiary details such as a mismatched account name or wrong IBAN, which can delay or misdirect a payment.
• Assuming OUR charging guarantees the full amount arrives. It reduces the risk of shortfall but does not eliminate it in every corridor.
• Failing to confirm the supplier’s expected received amount before sending, leading to disputes when the credited amount falls short.
• Sending a time-sensitive payment just before a cut-off or bank holiday without checking whether it will be processed in time.
• Assuming all regulated providers carry the same protection. FSCS deposit insurance, safeguarding under authorised PI or EMI status, and registration as a small payment institution represent different levels of protection.
• Using an unverified provider without checking the FCA Register, or dealing with a legal entity different from the one shown on the register.
• Not keeping records of the exchange rate, fee, payment reference, and confirmation for each transfer, making reconciliation harder.

Which International Payment Setup Fits Your Business?

The mechanics we’ve covered in this guide apply to every business international payment. What changes is which features you actually need, and that comes down to how often you transfer, how much you move, which currencies you deal in, and whether anyone else has to approve a payment before it goes.

• Occasional overseas payments: prioritise recipient amount and total cost. Simplicity is usually more important than feature depth.
• Regular supplier payments: look for reusable beneficiary records, predictable pricing, local-currency payment capability, and reconciliation support.
• International payroll or multiple recipients: batch payment capability, approval controls, and per-recipient tracking become important.
• Multi-currency trading: multi-currency account balances, local receiving account details, and accounting integrations matter.
• Large or future-dated payments: consider specialist FX support, forward contracts, transfer limits, and currency risk management tools.
