Did the bank send money you never meant to move? A UK bank transfer complaint follows different rules depending on whether you never approved the payment, a scammer talked you into it, or you typed the wrong account details. Start with the sending bank, and report any loss urgently.
Make it clear if you want the matter treated as a formal complaint. Thing is, a payment you never approved, a payment sent to the wrong account, and one you were tricked into sending are not the same claim. Banks route cases by that label.
Match the problem to the right route
Pick the row that matches what actually happened.
| What happened | What to ask the bank to do | What usually controls the issue |
|---|---|---|
| You did not authorise the payment | Report it as unauthorised and request reimbursement | Payment Services Regulations 2017 and the bank's fraud investigation |
| You were persuaded to make the payment by a scammer | Report an authorised push payment, or APP, scam and ask whether reimbursement rules apply | APP scam reimbursement rules, bank procedures, and the complaints process |
| You entered the wrong account details | Ask for an urgent payment recovery attempt | The bank's recovery process and rules on incorrect payment details |
| The bank sent a payment incorrectly or it has not reached the recipient | Ask for a trace, proof of execution, and correction or refund where appropriate | Payment execution rules and the bank's transfer terms |
| A transfer is delayed, especially overseas | Ask which payment rail was used and request a trace reference | Bank terms, payment-system processes, and the UK firm's handling of the transfer |
The legal home for many account-to-account payments is Part 7 of the Payment Services Regulations 2017, which sets rights and duties around execution, consent, and refunds. Failed payments are not automatic refunds.
Card chargeback is a separate process, and it normally doesn't apply to a bank transfer sent directly from your account. Leave that route to one side.
Act before the trail goes cold
A complaint can sit alongside a fraud report, a payment trace, or a recovery attempt. Get the urgent work done first.
-
Contact the sending bank through a trusted channel. Call the number on the back of your card, or use the official app or the bank's own website. Ignore phone numbers that arrived in a suspicious message.
-
Ask the bank to secure the account if needed. Someone may have got into the account. Ask about blocking cards, changing security details, and reviewing recent payments.
-
Collect the payment record. Keep the amount, date, time, payment reference, recipient name, sort code and account number or IBAN, screenshots, and any messages tied to the payment.
-
Say whether this is a formal complaint. Banks don't always log a fraud report or a transfer trace as a complaint. Use the words "formal complaint" if you are unhappy with the handling, the decision, a delay, or a refusal to reimburse.
-
Keep one timeline. Write down every call, case number, name, promised update, and reply. Escalation is easier with that record.
Tell the bank if the missing money means you can't cover rent, food, bills, or another essential payment. Keep the explanation factual.
Deadlines worth diarising
Diary the dates that match your route. They're not all the same.
| Route | Usual deadline or timing |
|---|---|
| Unauthorised payment redress | Notify the bank without undue delay after becoming aware of it, and normally no later than 13 months after the account was debited |
| Bank's formal complaint response | You may take the complaint to the Financial Ombudsman Service if the bank has issued a final response or eight weeks have passed |
| Financial Ombudsman Service referral | Normally within six months of the bank's final response |
| Older complaints | Usually within six years of the event, or three years from when you knew, or should reasonably have known, you had cause to complain |
Regulation 74 is the notification rule for unauthorised or incorrectly executed payment transactions. Exceptions exist, so don't drop a case only because a date looks tight.
Eight weeks is the usual complaint clock, not the only one. For certain fraud and unauthorised-transaction complaints, the Ombudsman explains that firms have a 15-working-day response standard, with limited extra time possible in exceptional cases, which is a response deadline rather than a promise that every claim will be paid.
Skip the wait for month 13. Report early so the bank has a better chance of stopping, tracing, or recovering the money.
If the transfer was unauthorised
You did not consent. That is what unauthorised means here: someone used the account, often through the app, and moved money you never agreed to send.
A scam you approved is different. The hole in the balance can look the same, yet the legal route is not.
The Payment Services Regulations set the timing. The bank must generally reimburse an unauthorised payment immediately, and no later than the end of the next business day after it becomes aware of the claim. Exceptions apply, including where the bank has reasonable grounds to suspect fraud and reports that suspicion to the relevant authority.
Don't call this automatic "zero liability." The bank may still look at the security facts.
Give a clear account of what happened, when you spotted it, when you first contacted the bank, and try not to tidy the story into something neater than it was, because the security questions (lost phone, shared password, a code you typed) are the facts the bank will actually weigh.
The Financial Ombudsman Service guidance on unauthorised transactions and identity theft shows the sort of issues it considers if a dispute reaches the Ombudsman.
If a scammer persuaded you to send the money
An APP scam is a payment you made yourself after a criminal talked you into it. A fake investment pitch is a common one. So is an impersonation call, a romance scam, or a bogus invoice.
Report it as an APP scam, not just a "fraudulent transfer." Ask the bank whether the payment is eligible for scam reimbursement and which payment route was used. Eligibility can depend on the payment type and on which firms were involved.
Send the advert, chat, email, phone number, website, invoice, and payment details. Include the exact story you were told.
To be honest, shame can make people leave out key facts. Don't. The bank and Ombudsman need an accurate account, even if the warning signs look obvious now.
If the bank declines reimbursement, ask for its decision in writing. Then make a formal complaint if the explanation is thin or the evidence you sent was ignored.
If you sent money to the wrong bank account
A wrong-account payment is usually harder to reverse than an unauthorised one. If you entered valid account details that belonged to somebody else, the bank may have executed the instruction exactly as given.
Ask it to start its payment-recovery process immediately and confirm what it has done. Closing the file without that attempt is not good enough.
Providers must make reasonable efforts to recover funds where a payer gave an incorrect unique identifier, such as the wrong account number or IBAN. Recovery isn't guaranteed, though. The recipient may already have spent the money, or may sit outside the UK.
Give the bank the date, amount, payment reference, intended recipient details, and the details you entered. If the transfer was shown as completed but your intended recipient did not get it, ask for a trace and confirmation of where the bank sent the funds.
The Ombudsman's disputed-transactions guidance notes that payment instructions and transaction details are central evidence in these cases.
Don't expect the receiving bank to discuss another customer's account with you. Privacy rules can limit what it can reveal.
If the transfer is delayed or international
Ask for a trace rather than treating "pending" as the last word. The bank should be able to explain the payment route, when it accepted the instruction, whether it was rejected or held, and what information it still needs. Screening checks, a cut-off, or an intermediary can stall it. International transfers often take longer because several firms each see only part of the journey.
Turns out a second payment, sent because someone said the first one was stuck, is a common way for a loss to grow. Don't send a second payment.
Complain first to the UK bank or payment firm that accepted your instruction. The Financial Ombudsman Service can consider complaints about eligible UK-regulated financial businesses, but it isn't a general complaint route against every overseas intermediary.
Write a complaint the bank can investigate
Keep the complaint brief and specific. You don't need legal language or a long argument.
Subject: Formal complaint about bank transfer [reference]
I am making a formal complaint about a [unauthorised / scam / delayed / incorrectly executed / wrong-account] transfer.
The payment was for [amount] on [date and time] to [recipient details]. The reference was [reference].
I reported the issue on [date] and was given case reference [reference]. I am unhappy because [brief reason].
I want the bank to [reimburse the payment / trace it / begin recovery / explain its decision / refund a specific loss].
I have attached [screenshots, messages, statements, invoices, or other evidence]. Please send your final response in writing.
Ask for a remedy that fits the problem. A delay may need a trace and an explanation; a bank error may need correction and repayment of a proven loss.
There is no automatic right to 8 percent interest or a fixed payment for distress simply because a transfer went wrong. If you lost money through the bank's error, list the actual cost and attach proof.
Taking the complaint to the Financial Ombudsman Service
The Financial Ombudsman Service, or FOS, is free for consumers. You can refer the matter once the bank sends its final response or eight weeks have passed without a decision.
Send the bank's final response, your complaint, transaction records, timeline, and any evidence you provided to the bank. Explain what outcome you think is fair and why.
The usual eight-week and six-month stages, plus the longer limits that can apply to older complaints, are set out in the UK Parliament's summary of financial-service complaints. The FOS can consider complaints about many FCA-regulated firms, subject to its jurisdiction rules and exceptions.
If you accept an Ombudsman decision, it becomes binding on the business. Think before you accept, because that can affect your ability to pursue the same complaint in court.
Pull the transfer reference out of the app now. Save the screenshots, then contact the sending bank through its official channel. If that answer does not fix it, put the complaint in writing while the details are still clear.
