You lost money to a crypto scam. You reported it to your bank. Then came the response: your refund has been refused because you acted with gross negligence.

It is one of the most frustrating things a fraud victim can hear. It does not just refuse the refund. It often feels like blame. The bank may suggest that you should have known better, even though criminals built trust, used professional-looking platforms, sent convincing messages and manipulated you into believing the investment was genuine.

Here is the important point: gross negligence is a high bar. It is not the same as making a mistake. It is not the same as trusting a scammer who appeared credible. It is not the same as failing to spot every warning sign in a sophisticated fraud.

Under the APP fraud reimbursement rules, a bank or payment provider must prove that the customer’s conduct reached the gross negligence threshold before relying on that exception. If your bank has simply used the phrase without properly explaining why, that refusal may be challengeable.

What the APP fraud rules give you

Since 7 October 2024, mandatory reimbursement rules have applied to many authorised push payment scam claims involving Faster Payments and CHAPS transfers.

APP fraud happens when you are tricked into authorising a payment yourself. Crypto scams often work this way. You may believe you are sending money to an investment account, trading platform, broker, wallet provider or recovery process. In reality, the payment is part of a fraud.

For in-scope payments made on or after 7 October 2024, payment firms are generally required to reimburse eligible victims unless an exception applies. The maximum mandatory reimbursement is £85,000 per claim. Firms may apply an excess of up to £100 in some cases, but not where the customer is vulnerable. Claims should usually be resolved within 5 business days, although the bank can pause the clock while it gathers necessary information. Even then, the outcome should normally be reached within 35 business days.

The rules apply to eligible customers, including consumers, micro-enterprises and charities below the relevant size threshold. They apply to UK Faster Payments and CHAPS transfers made to another UK account. They do not cover every type of payment. International transfers, card payments, cash withdrawals, civil disputes and pure cryptocurrency transfers sit outside the mandatory scheme, although other complaint routes may still exist.

That distinction matters for crypto scams. If you made a UK bank transfer as part of the scam, the bank’s handling of that transfer may still be open to challenge. But if the payment was made to an account in your own name at a crypto exchange, the mandatory reimbursement rules may not automatically apply in the same way. The Financial Ombudsman Service can still look at whether the bank acted fairly, whether it gave proper warnings and whether it should have intervened.

What gross negligence actually means

Gross negligence is more than ordinary carelessness. The Payment Systems Regulator treats it as a higher standard than ordinary negligence. The customer must have shown a significant degree of carelessness.

This is the part many refusal letters gloss over. A bank cannot simply say, “You ignored red flags.” It needs to identify what specific requirement you failed to meet and why that failure was grossly negligent.

The consumer standard of caution focuses on a limited set of behaviours. These include paying attention to a specific, directed scam warning, reporting the scam promptly once you realise or suspect what happened, responding to reasonable and proportionate information requests, and agreeing to the bank reporting the scam to the police or reporting it yourself where requested.

A generic warning is not enough by itself. Many bank payment screens contain broad warnings such as “beware of scams” or “are you sure you want to continue?” Those messages may be useful, but they are not the same as a tailored intervention that clearly tells you the bank believes this particular payment is probably a scam.

A tailored warning should be specific to the payment, the scam risk and the situation. If the bank wants to rely on you ignoring a warning, it should be able to show what the warning said, when it appeared, how clear it was, whether it was actively brought to your attention, and why it should have changed your decision.

Even if you continued after a warning, that does not automatically mean gross negligence. The bank and the Financial Ombudsman should look at the full circumstances, including how sophisticated the scam was, whether you were under pressure, whether you were being manipulated, and whether the bank could have done more.

What is not gross negligence

Being tricked by a professional scam is not automatically gross negligence.

It is not enough for the bank to say you should have known crypto scams exist. It is not enough to say the returns looked attractive. It is not enough to say you clicked an advert, trusted a fake broker or believed a platform that looked legitimate.

Crypto investment scams are designed to defeat ordinary caution. They often use fake dashboards, cloned websites, social media adverts, deepfake videos, staged reviews, Telegram groups, WhatsApp pressure and professional-looking onboarding processes. Some victims are groomed over weeks or months before the first payment is made.

If the scam was sophisticated, that helps your challenge. It shows that the issue was not simple carelessness but deliberate deception.

Vulnerable customers have extra protection

The gross negligence exception should not be applied to vulnerable customers in the same way. If you were vulnerable to the specific scam, the bank should not rely on the consumer standard of caution exception to refuse reimbursement.

Vulnerability can be temporary or long-term. It may include poor mental health, bereavement, relationship breakdown, serious illness, cognitive difficulty, financial pressure, isolation, disability or another personal circumstance that made you more susceptible to harm.

This is especially relevant in romance-related crypto scams, recovery scams and long-running investment frauds. Victims may be emotionally manipulated, isolated from outside advice or pressured into secrecy.

If your bank refused your claim without asking about vulnerability, or ignored circumstances you had already explained, that may be a strong ground for complaint.

How to challenge the refusal

Start by asking for the bank’s full reasoning in writing. Do not accept a short sentence saying you were grossly negligent. Ask the bank to identify exactly which requirement it says you failed to meet, what evidence it relies on, and why your conduct amounted to a significant degree of carelessness.

Ask for details of any warnings the bank says you ignored. You want the exact wording, timing and method of the warning. Was it a generic message shown to everyone? Was it specific to cryptocurrency? Did it name the risk clearly? Did it say the bank believed the payment was likely to be a scam? Did anyone from the bank speak to you before the payment was processed?

Gather your own evidence. Rebuild the story from the beginning. Keep screenshots of the advert, website, app, messages, emails, phone numbers, wallet addresses, transaction records, supposed account manager details, fake profit screenshots and any withdrawal demands. If the scammer coached you on what to say to the bank, keep that evidence too. It may show manipulation rather than deliberate dishonesty.

Our article on what evidence helps a missold car finance claim explains the general approach to evidence-gathering in financial disputes. The same discipline applies here: keep the timeline clear, preserve documents and explain what you believed at each stage.

Then make a formal complaint to the bank’s complaints team. Explain why you disagree with the gross negligence finding. Set out the sophistication of the scam, the steps you took, the lack of any specific warning, any vulnerability that applied, and why your behaviour did not meet the high threshold required.

Once the formal complaint is lodged, the bank usually has 8 weeks to issue a final response. If it does not respond in time, or if it maintains the refusal, you can escalate the complaint to the Financial Ombudsman Service.

Why the Financial Ombudsman matters

The Financial Ombudsman Service can look beyond the bank’s wording and assess what actually happened. It can consider whether the bank handled the claim fairly, whether the warning was good enough, whether the customer was vulnerable, whether the bank should have paused the payment, and whether the gross negligence label was justified.

This is important because banks do sometimes get these decisions wrong. A refusal letter is not the final word. The Ombudsman looks at each case on its own facts and can require a bank to refund money or pay compensation where it considers the bank’s decision unfair.

What if the money went through a crypto exchange?

Crypto scam cases often involve several stages. You may have transferred money from your bank account to a crypto exchange, bought cryptocurrency, and then sent the crypto to a wallet controlled by the scammer.

The mandatory reimbursement rules are focused on UK Faster Payments and CHAPS transfers to another UK account. They do not directly reimburse the later movement of cryptocurrency on-chain. They also may not automatically cover payments to an account in your own name at a crypto exchange, because the rules exclude payments to an account controlled by the customer.

However, that does not mean the bank has no responsibility. The Financial Ombudsman can still consider whether the bank acted fairly when processing the payment. For example, it may look at whether the payment was unusual, whether the bank knew or should have known crypto investment scams were a risk, whether its warning was meaningful, and whether it should have asked more questions before allowing the transfer.

So if the bank rejects your claim by saying, “It went to a crypto exchange, so we are not liable,” do not assume that is the end of the matter. The route may be different, but the decision can still be challenged.

Other financial issues worth addressing

If your bank has wrongfully refused an APP fraud claim, that may not be the only financial matter worth reviewing. Claim First handles a range of claims on a No Win, No Fee basis.

FAQs: Challenging a Gross Negligence Refusal

My bank just said I was grossly negligent without explaining why. Is that enough?

No. The bank should explain the specific basis for that conclusion. It should identify what requirement you failed to meet, what evidence it relies on and why your conduct was more than ordinary carelessness.

What if I missed the warning signs?

Missing warning signs does not automatically make you grossly negligent. Scams are designed to look real. The test is whether your conduct showed a significant degree of carelessness in the specific circumstances.

What if I ignored a warning from my bank?

It depends on the warning. A generic warning may not be enough. The warning should be specific, clear and relevant to the scam risk. Even then, the Ombudsman may consider the scam’s sophistication and why you continued.

What if I transferred money to a crypto exchange?

If the transfer was to an account in your own name, the mandatory rules may not automatically apply. However, you may still be able to challenge the bank’s conduct through a complaint and the Financial Ombudsman Service.

How long do I have to report the scam?

For mandatory APP reimbursement claims, you should report the scam as soon as possible and within 13 months of the final scam payment. Earlier is always better because it gives the bank more chance to trace and recover funds.

What if the scam happened before 7 October 2024?

The mandatory reimbursement rules apply to in-scope payments made on or after 7 October 2024. Earlier cases may still be assessed under other rules, including the CRM Code where applicable, or under the bank’s wider duties and the Financial Ombudsman’s fair and reasonable approach.

Your Bank’s Refusal Is Not the Final Word

A gross negligence refusal can feel final, but it is not. The bar is high, the bank carries the burden of proof, and the Financial Ombudsman Service can overturn unfair decisions.

If your crypto scam refund has been refused, do not accept a vague explanation. Ask for the evidence, challenge the reasoning and get support if you need it.
