UK IBAN for Business: What It Is and How to Get One (2026)

Q: Do I need a UK IBAN or a SWIFT code for international payments?

For SEPA transfers (euro payments within Europe), you need your IBAN and your bank's BIC code. For SWIFT transfers (non-euro currencies or payments outside the SEPA zone), you need the IBAN or account number and the BIC/SWIFT code. Both are included when you open a UK business account.

What is a UK IBAN?

An IBAN (International Bank Account Number) is a standardised format for identifying bank accounts internationally. It was created so that payment systems across different countries could reliably route funds to the correct account, regardless of how each country formats its domestic account details.

The UK has its own IBAN format, distinct from EU IBANs but following the same international standard. Every UK bank account has an IBAN — it is not a separate account or a special feature. It is simply the sort code and account number expressed in a standardised international format.

Many businesses only discover they need one when an overseas customer or supplier asks for it. A German client sending an invoice payment, a US marketplace paying out revenue, or a French supplier requiring your account details before dispatching goods — all of these scenarios call for your UK IBAN.

Key point

You do not apply for a UK IBAN separately. Every UK business account comes with one automatically. If you have a UK sort code and account number, you already have an IBAN — you just need to know what it looks like.

UK IBAN format: how to read it

A UK IBAN is always 22 characters long. It is built from four components, assembled in a specific order:

Structure: GB + 2 check digits + 4-letter bank code + 6-digit sort code + 8-digit account number

GB29 NWBK 6016 1331 9268 19

Country code — always GB for Great Britain. All UK IBANs start with GB.

Check digits — two digits calculated automatically using the MOD-97 algorithm. They validate the IBAN and catch typos.

NWBK

Bank identifier — the first four characters of the bank's BIC/SWIFT code. NWBK = NatWest Bank, for example.

601613

Sort code — the 6-digit sort code without hyphens. In this example, 60-16-13.

31926819

Account number — the 8-digit account number. Shorter account numbers are padded with leading zeros to reach 8 digits.

Spaces are added every four characters for readability when displaying an IBAN (e.g. GB29 NWBK 6016 1331 9268 19), but the spaces are not part of the IBAN itself. When entering an IBAN into a payment system, always enter it without spaces: GB29NWBK60161331926819.

You can convert any UK sort code and account number into an IBAN using publicly available IBAN calculators, or your bank or payment provider will display your IBAN directly in your account dashboard.

UK IBAN vs sort code and account number

The UK operates two parallel account identification systems that confuse many businesses — especially those used to dealing only in UK domestic payments. The short answer: they represent exactly the same account, just in different formats.

Format	Use case	Example
Sort code + Account number	UK domestic payments (FPS, BACS, CHAPS)	60-16-13 / 31926819
IBAN	International payments, SEPA transfers	GB29NWBK60161331926819
BIC / SWIFT code	Bank identification for SWIFT transfers	NWBKGB2L

For UK domestic transfers (paying UK suppliers, receiving GBP from UK customers, UK payroll), always use the sort code and account number. UK payment rails — Faster Payments (FPS), BACS, and CHAPS — expect sort code and account number format, not IBANs.

For international transfers — receiving EUR from a European supplier, sending USD to a US contractor, or receiving a SEPA payment from an EU business — use the IBAN and BIC.

Does a UK IBAN work with SEPA?

This is one of the most important and frequently misunderstood questions for UK businesses working with European partners. The accurate answer requires understanding what changed after Brexit and what did not.

What changed after Brexit

Before January 2021, UK IBANs were part of the SEPA zone as a matter of EU membership. After Brexit, the UK left the EU — but SEPA membership is separate from EU membership. SEPA is administered by the European Payments Council (EPC), which includes non-EU countries such as Norway, Iceland, Liechtenstein, and Switzerland.

The UK's status within SEPA became more complex post-Brexit. UK payment institutions can still apply for and maintain EPC SEPA scheme membership. However, not all UK banks chose to maintain this, and the position varies by institution.

The practical picture in 2026

Here is what this means for your business:

Sending EUR from UK to EU: Works via SEPA (if your UK provider is SEPA-connected) or via SWIFT. SEPA is faster and cheaper where available.
Receiving EUR from EU to a UK IBAN: Most major EU banks can send to UK IBANs. The transfer arrives as an international payment. Some EU banks may apply additional fees for transfers to non-EU IBANs.
IBAN discrimination: EU Regulation 260/2012 prohibits EU payment service providers from refusing to process cross-border SEPA Credit Transfers to reachable IBANs solely on the basis of the IBAN's country prefix. In practice, enforcement varies, but UK IBANs are broadly accepted.
SEPA-connected UK providers: UK payment providers that hold active SEPA scheme participation — like ARIDANG — process SEPA Credit Transfers directly, both inbound and outbound.

Bottom line

A UK IBAN is widely accepted for international euro payments. If your UK payment provider is connected to SEPA, you can send and receive SEPA transfers just as you could before Brexit. If your provider is not SEPA-connected, euro transfers route via SWIFT — which is slower and typically more expensive.

UK IBAN for foreign companies

Foreign companies that open a UK business account receive a UK IBAN in exactly the same way as a UK-registered company. There is no difference in how the IBAN works or what it can be used for.

This matters because a UK IBAN carries significant practical advantages for internationally-active businesses:

Wide international recognition: UK IBANs are recognised by payment systems in 200+ countries. Counterparties worldwide are familiar with GB IBANs.
GBP payments from anywhere: Clients and partners globally can send GBP to your UK IBAN via SWIFT.
Multi-currency inbound transfers: USD, CAD, CHF, EUR, and other currencies can be received via SWIFT.
UK financial system credibility: Operating with a UK IBAN signals participation in a well-regulated, internationally respected financial system — useful when dealing with UK counterparties or those who prefer UK banking relationships.
SEPA access for euro payments: With a SEPA-connected provider, your foreign company can send and receive SEPA transfers using the UK IBAN.

For non-UK companies

Companies registered in Germany, Spain, the Netherlands, the USA, Canada, and many other countries can open a UK business account and receive a dedicated UK IBAN. No UK address, director, or local presence is required in most cases. See our non-resident UK account guide →

Frequently asked questions

What does a UK IBAN look like?

A UK IBAN is always 22 characters long and begins with GB followed by 2 check digits, a 4-letter bank identifier, the 6-digit sort code, and an 8-digit account number. For example: GB29 NWBK 6016 1331 9268 19. Spaces are added for readability but are not part of the functional IBAN. When entering it into a payment system, use the version without spaces.

Is a UK IBAN the same as a sort code and account number?

Yes — a UK IBAN contains exactly the same information as a sort code and account number, expressed in a standardised international format. The sort code and account number are embedded within the IBAN. For UK domestic payments (FPS, BACS, CHAPS), use sort code and account number. For international payments, provide the IBAN and BIC.

Can I receive SEPA payments with a UK IBAN?

Yes, in most cases. After Brexit, UK IBANs are no longer automatically within the SEPA zone, but many EU banks and payment providers still process euro transfers to UK IBANs. UK payment providers that maintain active SEPA scheme membership — such as ARIDANG — can send and receive SEPA Credit Transfers. Some EU banks may charge additional fees for outbound transfers to UK IBANs, so it is worth confirming with your EU counterparty.

Can a foreign company get a UK IBAN?

Yes. Any company that opens a UK business account receives a UK IBAN automatically — regardless of where the company is incorporated. Companies registered in the EU, USA, Canada, or elsewhere can open a UK business account and receive a dedicated UK IBAN tied to their account. No UK address, UK director, or local presence is required in most cases.

Do I need a UK IBAN or a SWIFT code for international payments?

You typically need both: the IBAN identifies your specific account, and the BIC/SWIFT code identifies your bank. For SEPA transfers (euro payments within the SEPA zone), provide your IBAN and BIC. For SWIFT transfers (non-euro currencies or payments from outside the SEPA zone), the sender also uses your IBAN and BIC. Both are included in your ARIDANG account details from day one.
