If a scammer talked you into a UK bank transfer, an on-screen warning doesn't automatically end your complaint. For an eligible consumer APP scam sent through Faster Payments or CHAPS, the mandatory reimbursement rules generally cover payments authorised on or after 7 October 2024, up to GBP 85,000 per claim.
Start with the payment route. Then report the transfer quickly, save the warning, and ask for a written decision. The provider may consider the warning, your response, the reporting delay, and the rest of the evidence.
APP means authorised push payment: you approved the transfer, but deception led you to do it. An unauthorised payment is different because someone else used your account without permission. Tell the provider which type of payment you're reporting.
Start with the payment rail
Coverage turns on how the money moved. It doesn't turn on the logo at the top of your banking app.
The Faster Payments and CHAPS reimbursement rules took effect on 7 October 2024. They cover eligible consumers, micro-enterprises, and charities with annual income of less than GBP 1 million, subject to the scheme's exceptions, as described in the Financial Ombudsman Service guidance on APP fraud.
Find out which route carried the payment. Ask the bank to confirm it in writing.
Report the scam as soon as you suspect it. The outside reporting limit is generally 13 months after the last relevant payment was authorised, according to PwC's explanation of the PSR final rules.
If the claim is eligible, reimbursement should usually arrive within five working days. The provider may take up to 35 working days to investigate, as the FCA explains in its guidance on fraudulent payments.
An excess of up to GBP 100 may apply. Ask how the provider calculated it and how it considered any vulnerability or accessibility issue.
This is a route-specific scheme, not universal transfer insurance. A payment authorised before 7 October 2024, an international route, a card or wallet payment, or a transfer outside Faster Payments and CHAPS may need a different analysis. Other protections or provider terms may still apply, so ask which rules control your complaint.
Losses above GBP 85,000 need separate attention. Make the mandatory reimbursement claim first, then ask how the provider will assess the remaining loss.
What a bank warning does, and does not, prove
Your bank may say you ignored a warning. Answer that point directly. The alert still doesn't decide every issue in the complaint.
A warning may form part of an exception analysis, including an allegation of gross negligence. The relevant details include the warning's wording and timing, the sophistication of the scam, the bank's intervention, and your circumstances.
Common warning signs include:
- Pressure to act immediately or keep the payment secret.
- A new payee, changed bank details, or an account with no clear connection to the recipient.
- Instructions to move money to a supposedly safe account.
- Requests for a test payment, remote access, cryptocurrency, or extra fees.
- A caller claiming to be from your bank, the police, HMRC, a solicitor, or your employer.
- A message telling you to ignore an app warning or bypass a security check.
Treat these as facts to explain, not a scorecard. Save the exact warning screen if you still can. Its wording and timing may matter more than the fact that an alert existed.
Points the provider may raise
A useful response deals with the reason the provider actually gave. Ask for specifics if the refusal uses a broad label.
| Bank's concern | What to address in your complaint |
|---|---|
| A clear warning was ignored | Quote or attach the warning, explain what you understood, and say whether it appeared before or after authorisation. |
| The report was delayed | Give the date and time you first suspected fraud, when you contacted the bank, and the reason for any gap. |
| No independent verification was made | Describe the checks you attempted and why the scammer's information seemed credible at the time. |
| The bank alleges gross negligence | Ask it to identify the exact conduct behind that allegation. Ordinary carelessness and gross negligence aren't the same label. |
| The payment category is disputed | Ask whether it was Faster Payments, CHAPS, an international transfer, a card transaction, or another route. |
| The loss exceeds the scheme cap | Separate the mandatory reimbursement claim from the remaining loss and ask what complaint route applies to the balance. |
Thing is, a clear warning can weaken your case without settling it. Ask the provider to say exactly what the warning said, when it appeared, and which exception it says applies.
Red flags by scam type
Impersonation and CEO fraud may use a senior person's name, a fake fraud-team call, or an urgent request to change supplier details. Contact the person or organisation through a number you already trust. Never use the number in the suspect message.
Invoice redirection involves a genuine-looking invoice with altered bank details. Check any account change with the supplier through its established contact details, especially if the request arrives just before a payment deadline.
Romance, investment, job, and task scams often build confidence before asking for money. Guaranteed returns, fees to unlock earnings, pressure to borrow, and demands for secrecy are strong warning signs. A convincing website doesn't establish that a broker or employer is genuine.
What to do after a suspicious transfer
Move quickly. Create the written record at the same time.
- Call the sending bank or payment provider immediately. Use the number on your card, statement, or official app. If the suspected scammer has just called, use another phone line or wait at least 15 minutes before contacting the bank, as Which? advises. Ask for the fraud team, a payment recall, and a case reference.
- Describe the deception precisely. Give the payment date, amount, recipient details, messages used, warnings shown, and the time you reported the matter. Ask whether the payment travelled through Faster Payments or CHAPS.
- Preserve the record. Keep screenshots, emails, message histories, call logs, invoices, bank statements, payee details, and every warning screen. Report the incident through the appropriate UK fraud or police channel separately if needed.
- Send the reimbursement request in writing. If the payment appears to be in scope, ask the provider to assess it under the APP reimbursement rules. Request a written explanation if it refuses, delays, applies an excess, or relies on an exception.
Stop negotiating with the scammer. The bank needs the evidence, not another promise from the person who deceived you.
Put the evidence in a usable order
Forty screenshots still don't make a timeline. A short chronology lets the reviewer see what happened without guessing.
| Evidence | What it should show |
|---|---|
| Timeline | When contact began, when the payment was authorised, when warnings appeared, and when you reported the scam. |
| Payment record | Amount, date, recipient account, payment reference, and whether the transfer completed. |
| Messages and emails | The request, impersonation, pressure, account changes, and promises made. |
| Bank warnings | The exact screen, SMS, call, or intervention shown before authorisation. |
| Call record | Numbers used, dates, times, and what the bank or scammer said. |
| Personal circumstances | Health, accessibility, age, bereavement, or other facts that affected how you responded. |
| Complaint trail | Case number, fraud report, written claim, bank replies, and final response. |
Keep original files where possible. Cropped screenshots can remove dates, sender details, or other useful context.
HSBC, Monzo, Revolut and other providers
HSBC, Monzo, Revolut, and other providers may use different warnings, fraud teams, and account entities. Save the exact wording shown in the app or online banking service, then ask which UK entity handled the payment and which payment rail it used.
Turns out, the brand name tells you less than the route. A Revolut transfer, Monzo payment, or HSBC payment should not be assessed from the brand alone. The date, recipient, warnings, reporting speed, and responsible entity all matter.
Wise and PayPal need extra care. Ask whether the service sent the money, held it in a wallet, or merely funded another account. An international Wise transfer or a PayPal wallet dispute may follow different terms from a Faster Payments APP claim.
Treat fixed rejection percentages for named banks cautiously. Unless a figure identifies the rail, period, sample, and complaint type, it can't predict your case.
If the bank refuses reimbursement
Use the provider's formal complaints process, not just a fraud chat or telephone note. Ask for a final response that identifies the payment rail, the warning relied on, any alleged exception, the treatment of vulnerability, and the calculation of any excess.
A firm generally has up to eight weeks to issue a final response. If the complaint remains unresolved or the response is unsatisfactory, you can usually refer it to the Financial Ombudsman Service within six months of that response. The service is free, and its APP fraud guidance considers both the customer's actions and the bank's safeguards.
The ombudsman may award interest, usually calculated at 8% simple interest per year. It may also award money for distress or inconvenience, depending on the facts. It won't simply apply a published bank rejection rate.
You can write:
I was deceived into authorising the payment on [date]. Please confirm the payment rail and assess my claim under the applicable APP reimbursement rules. If you rely on a warning, gross negligence, fraud, or another exception, please identify the specific facts and provide the warning or intervention record.
To be honest, don't wait to perfect the complaint. Call the official fraud channel today, request the payment-rail and recall details, and submit the written claim. Mark the date eight weeks after your formal complaint, then note the six-month deadline from any final response.
