If someone uses your credit card without permission in England, you have clear legal protections. Understanding what counts as unauthorized use, how the law treats it, and what steps you can take helps you respond effectively if it happens to you.
Unauthorized use means someone has used your credit card—or your card details—without your consent. This includes:
The key word is consent. If you didn't agree to the transaction, it's unauthorized—regardless of who made it or how they got your information.
England's consumer credit laws provide robust protections for cardholders. The primary safeguard is the Consumer Rights Act 2015 and regulations governing payment services.
Your main legal position: You are not liable for unauthorized transactions if you have not acted fraudulently and have taken reasonable care of your card and details.
This means:
The burden of proof sits with your card issuer to show you authorized a transaction—not the other way around.
Your liability depends on specific circumstances:
| Scenario | Your Typical Position |
|---|---|
| Card stolen; you report it promptly | No liability for unauthorized use after reporting |
| Card lost; you failed to report for extended time | You may face limited liability (varies by card terms) |
| You shared your PIN or password willingly | Your protection is weaker; may be treated as authorized |
| Data breach or online fraud (card not physical lost) | Full protection; you have no liability |
| Family member used card without permission | Depends on whether you enabled access; may affect liability |
The Payment Services Regulations 2017 set the legal framework: issuers must refund unauthorized transactions unless you acted fraudulently or with "gross negligence."
Contact your card issuer immediately. Most banks have fraud lines available 24/7. Report the unauthorized transaction as soon as you notice it.
Provide a clear account of what happened—when you noticed the fraud, whether your card was lost or stolen, and what transactions weren't yours.
Request a refund in writing if the bank doesn't act quickly. Your issuer is legally required to investigate and typically refund within 10 business days if the transaction is confirmed as unauthorized.
Keep records of all communications, transaction dates, and any evidence (receipts, statements, correspondence).
Consider reporting to police if the amount is significant or if you suspect organized fraud. You'll need a crime reference number for some disputes.
For the person who used your card: Using someone else's credit card without permission is a criminal offense in England under the Fraud Act 2006 and the Theft Act 1968. This can result in prosecution, fines, or imprisonment depending on the amount and circumstances.
For you as the cardholder: You face no criminal or civil liability for unauthorized use you genuinely didn't authorize, provided you've acted reasonably (reporting the card promptly, protecting your PIN, etc.).
Your card issuer may dispute your claim if:
In these cases, you may need to provide evidence or challenge the issuer's position through dispute resolution.
If your card issuer refuses to refund unauthorized transactions, you can escalate to the Financial Ombudsman Service (FOS)—a free, independent dispute resolution service. The FOS can investigate whether the bank acted fairly under consumer law.
For larger disputes or complex fraud cases, consulting a solicitor specializing in consumer credit law may be worthwhile.
The bottom line: English law strongly protects you from unauthorized credit card use. Your liability is minimal if you've taken reasonable care of your card and reported fraud promptly. The card issuer bears the financial responsibility. Your next step depends on your specific situation—how the fraud occurred, how quickly you reported it, and how your issuer responds—but the legal framework is clearly in your favor.
