What a fake BT call sounds like

A BT scam call is a phone call from a criminal pretending to be BT, Openreach, or a broadband technical team. An example of the style is: Hello, this is BT technical support. We have detected a serious problem with your router and your broadband will be disconnected within 24 hours unless we fix it now.

Other versions offer a refund, compensation, a speed upgrade, or help with a "hacked" router. The aim is to get you to install remote-access software, log in to online banking, move money, or read out a code.

Why a fake BT call is so convincing

Caller ID is not reliable proof. Scam callers can make a call look as if it comes from a recognisable company, a local number, or a normal UK landline. They may also know your name, address, or broadband provider, which can make the call feel legitimate.

The safest rule is behavioural: an unexpected caller who asks you to install remote-access software, log in to online banking, move money to a "safe account", share card details, or read out a one-time passcode is not handling a normal broadband support issue. Hang up and verify independently.

Signs a BT call is a scam

• The call is unexpected and claims a serious problem with your router, broadband, line, or account.
• The caller says your broadband will be cut off unless you act immediately.
• You are asked to install remote-access software such as AnyDesk, TeamViewer, or a similar tool.
• You are asked to visit a website so the caller can "fix" your computer or router.
• You are asked to log in to online banking during the call.
• The caller offers a refund but needs bank details, card details, or screen sharing to process it.
• The caller says they refunded too much and asks you to send the difference back.
• You are asked for a password, one-time passcode, or card security code.

How the BT scam call works

First, the caller creates urgency or trust: a fault, hacking alert, refund, overcharge, or disconnection threat. Second, they ask you to install software, open a website, or log in to your bank. Third, they use screen access or pressure to make a payment, reveal a passcode, or create the appearance of a refund.

In the overpayment version, the caller may claim they sent too much money and ask you to return the difference. The apparent credit may be faked, temporary, or created by moving your own money between accounts. The money you send back is real and goes to the criminal.

How to check if a BT call is genuine

Do not act on instructions from an unexpected caller.

• Hang up.
• Do not install remote-access software because a caller asked.
• Do not log in to online banking while the caller is on the line.
• Do not read out one-time passcodes, card details, or passwords.
• Wait a few minutes, or use a different phone, then contact BT through the number on your bill or by typing bt.com yourself.
• If anything involved your bank account, call your bank using the number on your card or call 159, the Stop Scams UK service that connects customers safely to participating banks.

If you are unsure whether a website the caller sent is genuine, our guide on Is This Website a Scam? A Practical Checklist Before You Buy walks through the checks, and our ISP Impersonation Scams UK: BT, Sky, Virgin Media and Openreach Fraud Calls guide covers similar provider impersonation scams.

If you let them in or shared details

If you installed remote-access software or let the caller control your device, disconnect from the internet, remove the software, and run a security scan. Change important passwords from a different trusted device, especially email, banking, and shopping passwords.

If you logged in to your bank, moved money, shared card details, or gave a passcode, contact your bank immediately using 159 or the number on your card. Ask them to secure the account, check for payments and new payees, and stop or reissue cards if needed.

If you sent money by UK bank transfer on or after 7 October 2024, mandatory APP fraud reimbursement rules may apply to Faster Payments and CHAPS transfers. The PSR rules include a 13-month claim window, a maximum claim amount of £85,000, possible exclusions, and a possible excess of up to £100. Report the scam to your bank as soon as possible and keep notes of the call, payment references, phone numbers, and screenshots.

How to report a BT scam call (UK)

Tell BT through its official website or the number on your bill, especially if the caller used BT branding or knew account details.
