If you notice any suspicious activity on your bank account or accidentally transfer money to the wrong account, contact your bank as soon as you can.
You should also contact your bank if you think your bank card details have been stolen. Some banks may allow you to pause or stop bank cards from your online account or banking app.
If you think you’ve been scammed, you can report it to Action Fraud. Find out more on What to do if you’ve been scammed.
If your mobile or tablet is lost or stolen
If your device is lost or stolen, you should tell your network provider. If it's been stolen, call 101 to report it to the police straightaway.
If you used mobile banking on it, ask your bank to stop your mobile banking app. You can then start it again if you get a new device. If you have another device already, you may be able to use it to log into your online account and stop the banking app on the missing device yourself.
