Your child has shared financial details — such as bank account numbers, card details, online banking passwords, or payment information — online. This may have happened through a phishing scam, a game or app that requested payment details, a social media post, or a message to someone they trusted online.
It is very easy for children to share financial details without understanding the consequences. Whether they were tricked by a scam, convinced by an online contact, or simply made an error of judgement, the most important thing now is to act quickly and calmly. Swift action can significantly reduce the financial and personal impact.
Call the number on the back of your bank card or use your banking app to report the potential compromise. Ask them to freeze the affected account or card and flag any recent suspicious transactions. Most UK banks have dedicated fraud lines available 24 hours a day.
✗ Do not: Do not delay — the sooner the bank is informed, the sooner they can put protections in place. Every minute counts with card fraud.
If online banking passwords or login details were shared, change them immediately on every device. Also change any other accounts that use the same password. Enable two-factor authentication if it is not already set up.
Find out as precisely as you can what information was given — account number, sort code, card number, expiry date, CVV, PIN, or online banking password. Different information carries different levels of risk, and this will help the bank and Action Fraud assess the situation.
Report the incident to Action Fraud on 0300 123 2040 or at actionfraud.police.uk. Provide as much detail as possible about who the information was shared with, how, and when. If your child was deliberately targeted by a scammer, this is a crime and should be reported.
Explain what has happened and what you are doing to fix it. Make clear that they are not in serious trouble — many adults fall for similar scams. Use this as an opportunity to explain how scammers operate and what to watch for in future.
