Before you start

The warning signs

The golden rule

If someone contacts you out of the blue and asks you to do something with money, passwords or your computer: stop. Hang up or don't reply. Then contact the company yourself using a number you already trust (on your card, bill or their official website).

  • Pressure and panic: "Act now or your account will be closed", "Your computer is infected", "Police will arrest you".
  • Asking you to move money to a "safe account". Real banks never do this.
  • Asking for codes sent to your phone, your PIN or full passwords.
  • Asking you to install something so they can "fix" your computer (AnyDesk, TeamViewer and similar).
  • Unusual ways to pay: gift cards, vouchers, cryptocurrency, bank transfer to a person.
  • Keep it secret: "Don't tell the bank why you're moving the money."
  • Too good to be true: refunds, prizes, investments with guaranteed returns.

How to check safely

  1. Hang up or don't reply

    It's not rude. A genuine organisation will be happy for you to check.

  2. Use a number you already trust

    Call your bank on 159 (connects you to most UK banks safely) or the number on the back of your card. For other companies, use the number on a bill or their official website. Never use a number the caller, text or pop-up gave you.

    If you can, call back from a different phone, or wait a few minutes before calling, in case the scammer is still on the line.
  3. Talk to someone

    A quick chat with family, a friend or me often breaks the spell. Scammers rely on keeping you isolated and rushed.

How to report scam messages

  • Scam texts: forward them to 7726 (free). Your network investigates and can block the sender.
  • Scam emails: forward to report@phishing.gov.uk.
  • Scam calls: text 7726 with the word "Call" and the number that called you.

If you think you've been scammed

  1. Call your bank straight away

    Call 159 or the number on your card, any time, day or night. Tell them what happened. The sooner they know, the better the chance of stopping or recovering the money.

    Since October 2024, UK banks must usually refund people tricked into making a bank transfer (up to £85,000), as long as it's reported within 13 months. Card payments may be recoverable too. Don't be embarrassed to report it.
  2. If they had access to your computer

    Switch off your WiFi or unplug the internet cable. Don't use the computer for banking until it has been checked. Uninstall any program they asked you to install.

  3. Change your passwords

    From a different device, change your email password first (email lets people reset everything else), then online banking, then other accounts. Password guide

  4. Report it

    England, Wales and Northern Ireland: Report Fraud, 0300 123 2040 or reportfraud.police.uk (this replaced Action Fraud).
    Scotland: Police Scotland on 101.
    If you're in danger or it's happening now, call 999.

Stop and get help if
  • Anyone has had remote access to your computer: have it checked before using it for banking
  • You're being pressured right now: hang up, it's always OK to hang up
