Santander Phone Scam UK: What the Callers Say and How to Hang Up Safely
Scammers are calling Santander customers right now. Here's exactly what they say and how to fight back.
The call script: what Santander impersonators say
The call typically begins with a calm, professional tone: "Good morning, this is the Santander fraud prevention team. We've flagged some unusual activity on your account." The caller then mentions a specific amount — "a payment of £2,400 to an account you haven't used before" — to make the call feel credible. They ask you to verify your identity by confirming your date of birth, address, or account number.
Some variants go further. The caller asks you to log into your online banking "so we can see the transaction together", or requests the One-Time Passcode (OTP) that has just arrived on your phone, claiming it is needed for "security verification". Each of these requests is a fraud tactic: the OTP is what an attacker needs to approve a transaction or access your account from a new device.
The "we need to recheck your mobile details" variant
A variant to watch for involves a caller explaining that Santander is "updating its customer security system" and needs to verify the mobile number linked to your account. The caller may say this is "a regulatory requirement" or "standard procedure for all customers".
The goal is either to get you to read back the mobile number registered to your account (which the fraudster does not have), or to confirm a code sent to that number. That code is a genuine Santander authentication OTP — the fraudster has already triggered it by attempting to access your account or set up a new payee, and they need you to read it back to complete the action. Santander does not conduct mobile-detail rechecks by calling customers out of the blue.
What Santander will and will never ask for by phone
Santander may call you to flag account activity, and at the start of an outbound call they may ask you to confirm part of a memorable word or your date of birth to establish the call is with the right person.
Santander will never: ask for your full PIN, full online banking password, or full passcode; ask you to read a One-Time Passcode that has just arrived on your phone; ask you to move money to a "safe account" (no bank ever does this); ask you to install remote access software on your computer or phone; or advise you to give a false reason when withdrawing cash at a branch counter.
If the person calling you is asking for any of the above, the call is fraudulent, regardless of how professional they sound or what number appears on your screen.
The "safe account" instruction — the single biggest red flag
If a caller tells you that your money is at risk and instructs you to transfer it to a new account for safekeeping, hang up immediately. This is the defining feature of an authorised push payment (APP) fraud. Once money is transferred to the fraudster's account, recovery is not guaranteed even if you report it quickly.
UK banks are required to reimburse victims of APP fraud under Payment Systems Regulator rules in many cases, but the reimbursement process can take weeks and disputes arise over whether the victim took reasonable care. The safest outcome is to never authorise the transfer in the first place. No bank — including Santander — will ever ask you to move your money somewhere else to protect it.
What to do during and after the call
During the call: you do not have to stay on the line. Hang up. If you want to check whether there is a genuine account issue, call Santander yourself using the number on the back of your bank card or within the Santander app — never redial a number the caller gave you. On a landline, wait at least five minutes before calling out, as some fraudsters stay on the line after you hang up.
If you have already given details or authorised a transaction: call your bank immediately using the number on your card, and separately call 159 — the Stop Scams UK banking fraud shortline, which connects you directly to your bank's fraud team. Report the call to Action Fraud at actionfraud.police.uk or on 0300 123 2040. The case reference number Action Fraud gives you is useful when disputing any transaction with your bank.
Frequently asked questions
The caller ID showed Santander's real number — how can it still be a scam?
Phone numbers can be spoofed — scammers can make any number appear on your screen, including Santander's genuine number. This is called caller ID spoofing, and it means the displayed number is not proof the call is legitimate. The only safe approach is to hang up and call Santander back using the number on your bank card or via the Santander app.
Santander said they needed to recheck my mobile details in line with regulations. Is this real?
No. This is a recognised scam phrase. Santander does not conduct regulatory mobile-detail rechecks by calling customers out of the blue. If there is a genuine need to update your contact details, Santander would direct you to do so by logging into your account, not by reading information to an unsolicited caller.
I approved a transaction during the call — can I get my money back?
Contact Santander immediately, before doing anything else. UK banks are required to reimburse victims of authorised push payment (APP) fraud in many cases under Payment Systems Regulator rules, but this is not automatic and depends on the circumstances of the transfer. Also call 159 to reach the banking fraud line and report to Action Fraud at actionfraud.police.uk — the case reference helps when disputing the payment with your bank.
How do I verify that someone calling me is really from Santander?
You cannot reliably verify a caller's identity during an unsolicited call. The safe approach is always to hang up and call Santander back using the number on the back of your card or through the Santander mobile app. On a landline, wait a few minutes first — some fraudsters stay connected after you appear to hang up, ready to intercept your next outbound call.
Is it safe to give my date of birth or address to someone claiming to be from Santander?
Treat any unsolicited call as potentially fraudulent, regardless of what information the caller provides or requests. Even details that seem low-risk — date of birth, address, last four digits of your card — can be combined with other data to commit fraud or to pass security checks elsewhere. If there is a genuine issue with your account, Santander can address it when you call them back on the number from your card.
