SEPA vs SWIFT Payments: Difference, Process, and How to Choose

When it comes to international payments, two systems dominate – SEPA and SWIFT. 

Understanding the difference between the two matters practically for any UK business that pays suppliers, receives money from overseas clients, or manages transactions across multiple currencies.

In the following sections, we dive deep into how both systems work, compare them, and help you decide which one to use and when. 

What Is SEPA?

SEPA is an abbreviation for Single Euro Payments Area. This type of payment transfer makes it possible for individuals and businesses to make transfers in euros inter-country with the same convenience as they do when paying in their home country.

Currently, there are 41 countries in the SEPA zone. This includes 27 EU member states, 3 EEA countries, and 11 non-EEA countries. They all share a common goal – to harmonise electronic euro payments and provide simplicity, cost-effectiveness and convenience to consumers and businesses.

Businesses in the SEPA zone can make euro transfers to any other participating country using the same procedures they would for a domestic payment. This naturally eliminates the need to navigate different national banking systems or formats.

SEPA consists of four different processing schemes:

• SEPA Credit Transfer; 
• SEPA Instant Credit Transfer;
• SEPA Direct Debit (SDD); 
• SEPA Direct Debit Business-to-Business (SDD B2B).

Despite the fact that the UK is no longer part of the European Union following Brexit in 2020, the country is still a member of the SEPA zone. Most banking service providers in the UK continue to offer cross-border transfer solutions within the SEPA zone.

How SEPA Payments Work  

One important thing to understand about SEPA payments is that they require the use of IBANs and BIC codes. 

The International Bank Account Number (IBAN) identifies the recipient’s bank account, while the Bank Identifier Code (BIC), also known as the SWIFT code, identifies the recipient’s bank. 

Here is how a typical SEPA payment flows:

• Payment initiated in EUR – The sender instructs their bank or payment provider to send a euro transfer to the recipient’s IBAN.
  
• Processed via the SEPA clearing system – The sending bank submits the payment instruction to a SEPA clearing house, which validates the payment details and routes the instruction to the recipient’s bank.
  
• Funds credited within one business day – Standard SEPA Credit Transfers (SCT) are processed and credited to the recipient’s account within one business day of the payment being submitted.
  
• SEPA Instant option – SEPA Instant Credit Transfers (SCT Inst) enables funds to reach the recipient’s account faster – within ten seconds,  24 hours a day, seven days a week, including weekends and public holidays.

It’s important to note that SEPA instant payments are subject to a maximum transaction limit and require both the sending and receiving banks to support the scheme. 

What Is SWIFT  

SWIFT stands for Society for Worldwide Interbank Financial Telecommunication and is the standard mechanism for international wire transfers beyond the eurozone.

SWIFT is not a payment system in itself, but rather a global financial messaging network used by banks and financial institutions to communicate securely about international payment transactions.

When a bank initiates a cross-border payment, it sends a standardised SWIFT message to the recipient’s bank containing the payment instructions, account details, and transaction data.

SWIFT supports international payments in virtually any currency, including GBP, USD, EUR, JPY, and hundreds of others. This makes it the default choice for sending money internationally outside the SEPA zone.

How SWIFT Payments Work

SWIFT transfers are routed through a network of correspondent banks, which means that payment paths can vary. 

Here is the standard process:

• The sender initiates the international transfer – The sender provides the recipient’s IBAN or account number, the bank’s BIC/SWIFT code, the transfer amount, the currency, and any relevant payment reference.
  
• The bank sends a SWIFT message – The sending bank transmits a standardised SWIFT message to the recipient’s bank.
  
• Intermediary banks may process the payment – In many international SWIFT transfers, one or more intermediary banks handle the payment between the originating and receiving banks.
  
• The receiving bank credits the beneficiary account – Once the funds reach the recipient’s bank, they are credited to the beneficiary’s account.
  
• Currency conversion applied if needed – If the transfer involves two different currencies, for example, a GBP payment being received into a EUR account, currency conversion is applied either at the sending bank, an intermediary bank, or the receiving bank. 

Keep in mind that currency conversion fees and the exchange rate applied will affect the final amount received.

SEPA Vs SWIFT Payments: Key Differences  

While both SEPA and SWIFT enable secure money transfers between banks, they differ significantly: 

• Geographic scope: SEPA operates exclusively within the 41 participating countries that make up the SEPA zone. SWIFT operates globally, connecting financial institutions in over 200 countries, making it a suitable option for payments outside the SEPA area.
  
• Currency: SEPA transfers are denominated exclusively in euros. If the payment involves any currency other than EUR, SEPA cannot be used, and SWIFT is required. This is a critical distinction for UK businesses transacting in GBP or other non-euro currencies.
  
• Speed: SEPA Credit Transfers are complete within one business day as standard, with SEPA instant payments offering settlement in seconds where supported. Meanwhile, SWIFT transfers typically take between one and five business days, depending on the number of intermediary banks involved, the currencies in question, and compliance checks applied along the route.
  
• Fees: SEPA transaction costs are generally low and predictable – many banks charge little or nothing for standard euro transfers within the SEPA zone. SWIFT transfer fees are higher and more variable, as they may include charges from the sending bank, one or more intermediary banks, and the receiving bank. For high-value payments in particular, these cumulative charges can be significant.
  
• Intermediary banks: With SEPA payments, intermediary banks are rarely involved. On the other hand, SWIFT payments often pass through one or more correspondent banks, depending on the currency pair and the banking relationships involved, each of which may add time and cost to the transfer.

The following table summarises the core differences between SEPA and SWIFT:

	SEPA	SWIFT
Geographic scope	41 European countries	200+ countries globally
Currencies supported	EUR only	Multiple currencies, including GBP
Typical transfer speed	1 business day (instant option in seconds)	1-5 business days
Fees	Low and predictable	Variable and can be higher
Intermediary banks	Rarely involved	Commonly involved
Best for	Eurozone payments within SEPA	Cross-border or multi-currency transfers

How Long Do SEPA And SWIFT Payments Take  

Standard SEPA Credit Transfers are credited to the recipient’s account within one business day of the payment being submitted and accepted by the sending bank. 

Keep in mind that cut-off times apply. For example, payments submitted after the daily cut-off may not be processed until the following business day. SEPA instant payments, where available, reach the recipient’s account within ten seconds at any time of day or night.

On the other hand, SWIFT transfers typically take between one and five business days end-to-end. The exact transaction processing time depends on a range of factors. 

Weekends and public holidays in both the sending and receiving countries can extend timelines further.

Both SEPA and SWIFT payments can also be delayed by incorrect payment details or other issues. 

What Affects Transfer Costs And Speed  

Here are the factors that influence the cost and speed of international payments, no matter whether SEPA or SWIFT are used.  

Currency conversion fees 

Any transfer that involves converting from one currency to another will incur currency conversion fees. These are typically charged as a margin above the interbank exchange rate and can vary between banks and payment providers. 

In most cases, companies that regularly make cross-currency transfers can negotiate better FX rates and reduce costs. 

Intermediary bank charges 

In SWIFT transfers, each bank that handles the payment may deduct a handling fee before passing the funds along. 

The actual amount of these deductions is often unknown at the time of sending, which is why the recipient sometimes receives less than the original transfer amount. 

Cut-off times and weekends 

Banks also apply daily cut-off times for processing international payments, where those submitted after the cut-off will not be processed until the next business day. 

Weekends and public holidays in either the sending or receiving country can add further delays.

Compliance and AML checks 

Both SEPA and SWIFT transfers are subject to compliance screening under anti-money laundering (AML) and sanctions regulations. 

Payments that flag unusual patterns, are considered high-risk, or lack documentation, may need to undergo manual review, which can further delay processing.

Incorrect payment details 

Errors in the recipient’s IBAN, BIC, or account details can also result in delayed or returned payments. 

Returned payments typically accumulate additional bank charges and can take several business days to resolve. 

SEPA Vs SWIFT For UK Businesses  

As a business, if you want to handle international payment costs and timelines effectively, it’s key to understand when to use SEPA and SWIFT accordingly. 

If you are making or receiving euro-denominated payments to or from a business or individual in one of the 41 SEPA participating countries, SEPA is almost always the better option. The reason is that SEPA transaction costs are lower, speeds are faster, and the process is more straightforward than routing the same payment via SWIFT. 

Alternatively, SWIFT is the appropriate choice for any payment that falls outside the SEPA zone, including:

• Transfers in GBP;
• Transfers in USD;
• Transfers in any other non-Euro currency;
• Payments to countries outside the SEPA members;
• High-value international payments to overseas bank accounts in multiple currencies. 

For UK businesses with global supply chains or international client bases, the SWIFT network remains the primary route for sending money internationally.

Alternatives To SEPA And SWIFT Payments  

For UK businesses, SEPA and SWIFT are not the only options. 

Depending on the nature and destination of the payment, several alternatives may be faster, cheaper, or more appropriate:

• Faster Payments (UK domestic transfers) – Handles transfers in GBP for domestic payment methods within the UK, usually completing within seconds, 24 hours a day, seven days a week. Faster Payments are free or low-cost for most UK current accounts and are the standard for day-to-day domestic transfers up to £1 million.
  
• CHAPS (Clearing House Automated Payment System) – CHAPS is the UK’s high-value payments system, used for same-day sterling transfers, typically for property purchases, large business payments, and time-sensitive transactions.
  
• Card payments – For those receiving international payments, accepting card payments is often faster and simpler than waiting for bank transfers. Card payments settle to the merchant account within one to three business days and support a wide range of currencies.
  
• Fintech and payment platforms – Specialist fintech providers and payment processing services have disrupted traditional international payment methods. They offer faster transaction processing times, more competitive currency conversion fees, and greater payment tracking services than most high street banks. 

These alternatives are not interchangeable. They solve different payment problems. 

Faster Payments and CHAPS are primarily transfer rails for moving money between bank accounts, while card payments and payment platforms are often better suited to collecting money from customers. For example, a business requesting remote customer payments may find a tool such as myPOS Payment Request more practical than asking each customer to arrange a bank transfer manually. 

Managing International Payments And Cash Flow  

For UK SMEs, international payments aren’t just about choosing between SEPA and SWIFT. It’s about balancing speed, cost, and visibility across different currencies and payment methods.

Take into account factors like speed, cash flow, transparency, efficiency, and costs.

Platforms like myPOS offer a more streamlined approach by enabling businesses to accept payments in multiple currencies, manage funds via IBAN accounts, and access money faster. 

Conclusion  

Overall, SEPA and SWIFT serve distinct but complementary roles in the international payments landscape. 

The key factors to weigh when choosing between the two are geography, currency, speed requirements, and cost tolerance. By fully understanding the differences between SEPA and SWIFT, you can make the right choice for your business. 

Frequently Asked Questions

When scaling internationally, when does SWIFT become unavoidable?

SWIFT is not strictly unavoidable, but is often used when you need to send or receive payments outside the SEPA zone, transact in currencies other than euros, or work with countries where no regional payment alternative exists. While SWIFT is widely used for cross‑border payments, there are alternatives in many corridors: dedicated cross‑border payment networks (e.g., Visa B2B Connect, Mastercard Cross‑Border Services) and fintech providers that route funds over local clearing systems where possible.

When should I use SEPA instead of SWIFT for supplier payments?

Use SEPA whenever you are paying a supplier in euros within the 41 SEPA participating countries. It is faster, cheaper, and more predictable than routing the same payment via SWIFT.

What data do I need to send a SEPA vs a SWIFT payment correctly?

For a SEPA payment, you need the recipient’s IBAN and, in some cases, their BIC. For a SWIFT payment, you typically need the recipient’s IBAN or local account number, their bank’s BIC/SWIFT code, the bank’s name and address, and the destination currency. SWIFT transfers to certain countries may also require additional intermediary bank details.

How do failed SEPA payments differ from failed SWIFT transfers?

Failed SEPA payments are handled through standardised exception processes such as rejects, returns, and recalls, often with defined reason codes. Failed SWIFT transfers may require cross-bank investigations or cancellation workflows across intermediary banks, which can make resolution less uniform.

How do banks handle disputes or recalls in SEPA vs SWIFT?

SEPA recalls follow scheme-defined procedures for payment exceptions and recall requests. SWIFT recalls are handled through bank-to-bank cancellation and investigation processes, with Swift moving toward more standardised “Stop and Recall” case management for cross-border payments.

How do customers perceive SEPA vs SWIFT for refunds or payouts?

For euro payouts within Europe, SEPA is generally easier to communicate because it is standardised and relatively predictable. SWIFT payouts may feel less transparent to recipients when intermediary processing, investigations, or variable routing affect timing. This is an inference from how the two systems are structured.
