UK Banking Explained 2026 — Sort Codes, IBAN, Transfers & Digital Banks

This guide answers every common UK banking question — what sort codes and account numbers are, how IBAN and SWIFT codes work, how long bank transfers take, how to open an account, how to get a bank statement, and whether digital banks like Revolut and Monzo are safe.

Sort Codes, Account Numbers and Roll Numbers

Quick Answer

What is a sort code?

A sort code is a 6-digit number (displayed as three pairs, e.g. 20-00-00) that identifies your bank and branch in the UK. It is used alongside your account number to route payments to the correct bank. You need both your sort code and account number to receive a BACS payment or set up a direct debit. Find your sort code on your debit card, bank statement, or in your banking app.

Quick Answer

What is a bank account number?

A UK bank account number is an 8-digit number that uniquely identifies your account within your bank. Combined with your sort code, it identifies your specific account. Account numbers are printed on your debit card, cheque book, bank statements, and in your online banking app. Never share your account number and sort code publicly — while receiving money is safe, others could use it for fraudulent direct debits.

Quick Answer

What is a roll number in banking?

A roll number is used by some building societies (not banks) instead of or in addition to a sort code and account number. It is an alphanumeric reference (e.g. A1234567B) specific to building societies like Nationwide, Yorkshire BS, and Skipton. You need a roll number when making payments to or from a building society account. Find it on your passbook, statement, or building society app.

Quick Answer

What bank details are needed for a bank transfer?

For a UK bank-to-bank transfer (BACS/Faster Payments): you need the recipient's sort code (6 digits) and account number (8 digits), plus a payment reference. For building society accounts: sort code, account number, and possibly a roll number. For international transfers: IBAN and SWIFT/BIC code of the recipient’s bank.

IBAN and SWIFT/BIC Codes Explained

Quick Answer

What is an IBAN?

IBAN stands for International Bank Account Number. It is a standardised format for identifying bank accounts internationally. A UK IBAN is 22 characters: GB + 2 check digits + 4 letters (bank code) + 6-digit sort code + 8-digit account number. Example: GB29 NWBK 6016 1331 9268 19. You need an IBAN to send or receive international wire transfers to/from the UK.

Quick Answer

What is a SWIFT/BIC code?

A SWIFT code (also called BIC — Bank Identifier Code) identifies a specific bank internationally. It is 8 or 11 characters: 4 letters (bank code) + 2 letters (country code) + 2 characters (location) + optional 3-character branch code. Example: NWBKGB2L (NatWest UK). You need a SWIFT/BIC code when making international wire transfers. Find your bank’s SWIFT code on their website or on your bank statement.

CodeFull NameLengthUsed When
IBANInternational Bank Account Number22 chars (UK)Receiving international payments into a UK account
SWIFTSociety for Worldwide Interbank Financial Telecommunication8 or 11 charsIdentifying the receiving bank for international transfers
BICBank Identifier Code8 or 11 charsSame as SWIFT — the terms are interchangeable
Sort codeUK-only bank/branch identifier6 digitsUK domestic payments only
Account numberUK-only account identifier8 digitsUK domestic payments only

For transfers within the UK (Faster Payments, CHAPS, BACS): use sort code + account number only. For international transfers: use IBAN + SWIFT/BIC. Never use sort code and account number for international payments.

Bank Transfers — How Long Do They Take?

Quick Answer

How long does a bank transfer take?

UK Faster Payments transfers are usually instant — typically within 2 hours, often within seconds. CHAPS (same-day high-value transfers) complete the same working day if sent before the bank’s cut-off time. BACS (used for payroll and direct debits) takes 3 working days. International SWIFT transfers typically take 1–5 working days depending on the destination country.

Transfer TypeTypical TimeLimitUsed For
Faster PaymentsInstant to 2 hoursUp to £1,000,000 (varies by bank)Everyday transfers between UK accounts
CHAPSSame working dayNo upper limitHigh-value same-day transfers (e.g. property purchase)
BACS3 working daysNo upper limitPayroll, direct debits, supplier payments
International (SWIFT)1–5 working daysVariesTransfers to overseas bank accounts
International (SEPA — Europe)1–2 working daysVariesEuro transfers within SEPA zone

Quick Answer

How long does an international bank transfer take?

International bank transfers via SWIFT typically take 1–5 working days. Transfers to major currencies (USD, EUR, AUD) in major countries often arrive within 1–2 days. Transfers to less common currencies or countries with slower banking systems can take 3–5 days. Using services like Wise (TransferWise) or Revolut for international transfers is often faster and cheaper than bank SWIFT transfers.

Quick Answer

What is a bank wire transfer?

A wire transfer is an electronic transfer of funds between bank accounts, typically used for high-value or international payments. In the UK, CHAPS is the domestic wire transfer system for same-day high-value payments. SWIFT is the international wire transfer network used between banks globally. Wire transfers are more secure than cheques but may carry fees — especially for international transfers.

Quick Answer

Can a bank transfer be reversed?

Faster Payments can sometimes be recalled if sent to the wrong account. Contact your bank immediately — they will attempt to recover the funds under the Payment Services Regulations. Recovery is not guaranteed — if the recipient has already spent the money, your bank will need to take legal action. Report fraud immediately to your bank and Action Fraud (0300 123 2040).

How to Open a Bank Account

Quick Answer

What do I need to open a bank account?

To open a UK bank account you typically need: proof of identity (passport or driving licence) and proof of address (utility bill, council tax letter, or bank statement — dated within 3 months). Some banks also require your National Insurance number. Digital banks (Monzo, Starling, Revolut) can be opened with just a passport or driving licence selfie — no paper documents needed.

Quick Answer

How much cash can I withdraw from my bank?

Most UK banks allow cash withdrawals of £300–£500 per day from ATMs as a standard limit. In-branch withdrawals are typically unlimited for your own account, though large amounts (£10,000+) may require advance notice for cash to be available. Your bank may place temporary limits for security reasons — check your app or call your bank if you need a large withdrawal.

Quick Answer

How to transfer money from a credit card to a bank account?

This is called a money transfer. Some credit cards offer money transfer deals — Barclaycard, MBNA, and Virgin Money offer these. You transfer credit card funds to your bank account for a fee (typically 2–4% of the amount). Standard cash advances from credit cards are extremely expensive (typically 3% fee + 30%+ APR from day one) — avoid these. Only use a money transfer credit card with a 0% money transfer offer.

Bank Statements Explained

Quick Answer

What is a bank statement?

A bank statement is a record of all transactions in your account over a set period (usually monthly). It shows: opening balance, all credits (money in) and debits (money out), closing balance, and transaction dates and references. Bank statements are used for mortgage applications, visa applications, benefit claims, and tax returns.

Quick Answer

How to get a bank statement?

Download instantly from your online banking or mobile app (PDF). Request paper statements by post — most banks charge £1–5 per statement if you have opted out of paper. Request in-branch — most banks will print recent statements free of charge. For older statements (over 12 months): request via secure message in your app or by calling your bank — fees may apply.

Quick Answer

What is a bank giro credit?

A bank giro credit is a paper payment slip used to pay money into a bank account at a bank branch or post office. They are most commonly found at the bottom of bills (council tax, utilities, credit card statements). You take the slip with cash or a cheque to a branch and the funds are credited to the named account. Bank giro credits are increasingly rare as online payments have replaced them.

Is Revolut / Monzo / Starling a Real Bank?

Quick Answer

Is Revolut a bank?

Yes — Revolut received a UK banking licence in July 2024. It is now a fully licensed UK bank regulated by the PRA and FCA. UK customer deposits are protected up to £85,000 by the FSCS (Financial Services Compensation Scheme). Previously Revolut operated as an e-money institution, meaning deposits were not FSCS protected.

Quick Answer

Is Monzo a good bank?

Monzo is a fully FCA-regulated UK bank with FSCS protection up to £85,000. It consistently scores well in customer satisfaction surveys — Ofcom regularly rates Monzo highly for app quality and customer service. Monzo is best for: budgeting tools, spending notifications, fee-free overseas spending, and salary early access. It is less suited for: large savings (rates are competitive but not market-leading), business banking complexity.

Quick Answer

Is Starling Bank safe?

Yes — Starling Bank is fully authorised by the PRA and regulated by the FCA. Customer deposits are protected up to £85,000 by the FSCS. Starling consistently wins Which? Recommended Provider status and has high customer satisfaction ratings. It offers a free current account with no monthly fee, a linked savings space, and a business account.

DWP and Universal Credit Bank Queries

Quick Answer

How often do DWP check bank accounts?

DWP has the legal power to request bank account information from banks at any time to verify benefit claims. There is no fixed schedule — checks can be triggered by a change of circumstance report, a tip-off, or random compliance checks. DWP can access up to 12 months of bank statements. Failing to report a change in circumstances (e.g. receiving an inheritance or new income) is a criminal offence.

Quick Answer

What time does Universal Credit get paid into your bank?

Universal Credit payments are made on a set date each month (your payment date is shown in your UC journal). Payments are processed by DWP as a BACS transfer, which means funds typically arrive between midnight and 9am on your payment date. Some banks credit BACS payments early — Monzo and Starling often show payments the evening before.
