BT Broadband Tech Support Scam: How to Spot and Stop It in the UK
BT tech support scammers don't work for BT—but they're extremely convincing.
What is this scam?
The BT broadband tech support scam targets BT customers with cold calls, texts, or emails claiming there's an urgent problem with their broadband connection. Scammers pose as BT support agents and claim anything from a virus infecting your network to an illegal hacking attempt to a broadband fault. They create artificial panic by saying your connection is at risk, your data is being stolen, or your account will be locked unless you take immediate action. The goal is to get you to install remote access software (like AnyDesk or TeamViewer) so they can access your computer, or to trick you into paying for fake repair services or security software. Some variants ask for your BT account details, bank information, or payment card details. Real BT does offer genuine support, but they will never cold-call you about a virus or demand payment over the phone for security issues.
Warning signs to look for
- You receive an unsolicited call, text, or email from someone claiming to be BT support—BT rarely contacts customers about viruses or security threats unprompted.
- The caller has a strong accent or the line quality is poor; many scammers operate from overseas call centres.
- You're told there's an urgent problem that requires immediate action, creating pressure to act without thinking.
- The person asks you to install software like TeamViewer, AnyDesk, or Chrome Remote Desktop—legitimate BT support does not ask customers to do this.
- You're asked for sensitive information like your full account PIN, password, or payment card details over the phone or email.
- The scammer references a specific broadband fault code or technical issue that sounds plausible but you didn't report to BT.
- You're offered a discount or refund that requires you to buy security software or pay an upfront fee.
- The caller claims your bill is incorrect or overdue and demands immediate payment to avoid account suspension.
How this scam works step by step
The scam typically begins with a cold call, text message, or email claiming to be from BT technical support. The scammer has obtained your number or email address from various sources—previous data breaches, bought lists, or random dialling. They'll claim that BT's systems have detected a virus on your broadband connection, unusual activity on your account, or that your connection is compromised. To increase pressure, they may quote your account number or reference past issues (information often freely available if you've been part of a data breach). They then convince you to share control of your computer via remote access software like TeamViewer or AnyDesk. Once they have access, they'll show you fake 'evidence' of viruses or malware, install actual malware, steal passwords from your browser, or search for banking details. Alternatively, they'll convince you to pay for fake antivirus software, repair services, or device protection plans by credit card or bank transfer. In the worst cases, scammers use remote access to conduct online banking fraud directly from your machine, stealing thousands. The entire interaction may last 30 minutes to several hours, with the scammer building trust and urgency throughout.
How to verify if it is genuine
If you're unsure about a call, text, or email claiming to be from BT, follow these steps: First, hang up or do not reply immediately. Do not use contact details provided by the caller. Instead, look up BT's official phone number on your BT bill or visit bt.com directly (not a link from the email). Call that number to ask whether BT initiated contact with you. Genuine BT support will have a record of any contact they made. Ask the person claiming to be BT for specific details—like the exact issue they detected and when—and verify this independently online. Check your BT account online by logging in to My BT (mybt.bt.com) to see if there are any messages or alerts about your broadband. If you suspect a phishing email, forward it to BT's security team and report it to the NCSC. Never grant remote access to anyone who cold-called you. BT support staff will never ask for your full password or PIN over the phone. If you're still unsure, use Citizens Advice's scam checker or contact Action Fraud for guidance.
What to do if you have already interacted
If you've already engaged with the scammer, take action immediately based on what happened. If you installed remote access software: unplug your router, restart your computer in safe mode, and uninstall the remote access application immediately. Run a malware scan using Windows Defender or Malwarebytes. If you gave out your bank details, card number, or password: contact your bank or card provider straight away and freeze your account if possible. Change your passwords for BT, email, and online banking from a different device. Monitor your bank statements and credit file for suspicious activity. If you paid money: contact your bank immediately to request a recall of the payment or a chargeback. File a report with Action Fraud (0300 123 2040) and provide evidence of the transaction. If you gave remote access and they accessed your banking: contact your bank immediately, explain the situation, and ask them to review recent transactions and flag your account for fraud protection. Enable two-factor authentication on all important accounts. Document everything—screenshots, call logs, payment confirmations—as evidence for reporting.
Reporting this scam in the UK
If you've been targeted or scammed, report it to Action Fraud immediately by calling 0300 123 2040 (Monday to Friday, 8am to 8pm) or online at actionfraud.police.uk. Action Fraud will record the incident and pass information to law enforcement. If you received a phishing email impersonating BT, forward it to the NCSC Suspicious Email Reporting Service at report@phishing.gov.uk. If you received a suspicious SMS text, forward it to 7726 (spells SPAM). Report the incident to BT themselves by calling their official customer service line (found on your bill) to alert them that their name is being used in scams. This helps BT warn other customers and tighten security. Report the scam to Citizens Advice consumer helpline on 0808 223 1133 (lines open Monday to Friday, 9am to 5pm) for additional support and guidance. If money was lost, also report it to your bank's fraud team—they may be able to recover funds if reported quickly. Keep copies of all evidence: call logs, emails, screenshots, payment records, and transaction details.
Frequently asked questions
Is BT a legitimate company, or should I assume all BT contact is a scam?
BT is a legitimate UK broadband and phone provider, but scammers frequently use their name without permission. BT itself is genuine; the scam is when someone calls claiming to be from BT when they aren't. Always verify any unsolicited BT contact by calling BT directly using the number on your bill, never by using a number the caller provided.
What can I do if I've already sent money to the scammer?
Contact your bank or payment provider immediately and report the fraud. If you paid by bank transfer or card, ask them to initiate a recall or chargeback within the first few days—success depends on how quickly you act. File a report with Action Fraud on 0300 123 2040 and provide proof of payment. If a large sum was sent, contact your bank's fraud team and ask about freezing the recipient account. Unfortunately, recovery is difficult once money leaves your account, but reporting quickly increases the chances.
What should I do if I've already installed the remote access software they asked for?
Disconnect your router immediately and restart your computer in safe mode. Uninstall the remote access application (such as TeamViewer or AnyDesk) completely. Run a full malware scan using Windows Defender or a reputable antivirus like Malwarebytes. Change your passwords for BT, email, and online banking from a different device. If the scammer had access to your computer, monitor your bank account closely for unauthorised transactions. Consider placing a fraud alert on your credit file with Experian, Equifax, or CallCredit.
How do I report the scammer if I don't have their full details?
Report what you do have to Action Fraud (0300 123 2040 or actionfraud.police.uk): the phone number or email address they used, the date and time of contact, what they claimed, and any money lost. If you received a suspicious email, forward it directly to the NCSC at report@phishing.gov.uk with full headers intact. If it was a text, forward it to 7726. Even partial information helps authorities identify scam patterns and take action against organised scam networks.
