Nationwide Building Society has issued an urgent warning to customers across the UK after a sharp rise in increasingly sophisticated scam calls that are catching people off guard and, in some cases, costing them thousands of pounds.
The warning follows new research and reports showing fraudsters are using what Nationwide describes as “clever tactics” — including spoofed phone numbers, realistic scripts and carefully timed pressure — to impersonate genuine bank staff and manipulate customers into handing over sensitive information.
According to reporting by The Independent, scam calls have become so common that many UK adults now struggle to tell the difference between a real call from their bank and a fraudulent one.
For readers following consumer alerts on Swikblog, Nationwide’s message is blunt and unambiguous: if a call makes you feel rushed, anxious or unsure — hang up immediately.
Why these scam calls feel so convincing
Nationwide says modern scam calls are far removed from the obvious fraud attempts of the past. Criminals now use professional-sounding language, calm delivery and rehearsed scripts that closely mimic genuine bank conversations.
Many callers claim to be from Nationwide’s fraud or security team, warning that suspicious activity has been detected on an account. Others suggest that money is “at risk” and must be moved quickly to prevent theft.
To increase credibility, scammers may already know partial personal information — such as your name, address or recent transactions — obtained through data leaks or previous scams.
Common tactics include:
- Caller ID spoofing so the number appears to be Nationwide
- Claims that a payment has been flagged or blocked
- Urgent deadlines designed to stop you thinking clearly
- Instructions to keep the call secret “for security reasons”
Nationwide stresses that these tactics are deliberately designed to create panic, making people more likely to comply.
Nationwide’s clear advice: end the call
The building society is urging customers not to engage with callers once doubt creeps in. You do not need to prove who you are. You do not need to stay on the line. And you do not need to be polite.
Nationwide has repeated that it will never ask customers to:
- Share their full password or PIN
- Reveal one-time passcodes
- Move money to a “safe” or “holding” account
- Lie to bank staff or keep calls secret
If any caller asks for these things, Nationwide says customers should hang up immediately and contact the bank using official channels.
New ‘Call Checker’ feature explained
In response to growing concern, Nationwide has launched a new in-app tool called Call Checker, designed to help customers confirm whether a call claiming to be from the bank is genuine.
The feature allows customers to open the Nationwide app during a call and check whether the bank is actually trying to contact them. If there is no record of an outgoing call, customers are advised to end the conversation straight away.
Nationwide says this tool is part of a broader effort to give customers more confidence when dealing with unexpected calls, particularly as fraudsters become more sophisticated.
Official guidance is available on Nationwide’s fraud and security support pages.
Scam calls are rising across the UK
Survey data referenced in recent reporting suggests UK adults now receive an average of two scam or suspicious calls per week, with more than half saying they believe the number is increasing.
Despite this, fewer than one-third of people report scam calls to their bank, even when they suspect fraud. Nationwide says this under-reporting makes it harder to track criminal networks and protect other customers.
The bank is encouraging people to report suspicious calls even if no money has been lost, stressing that early reporting can help prevent wider harm.
What to do if you receive a suspicious call
- Hang up immediately if you feel pressured or uncertain
- Never share passwords, PINs or one-time codes
- Do not move money at the request of a caller
- Use your bank’s official app or website to verify contact
- Report the call to your bank, even if no loss occurred
As scam tactics continue to evolve, Nationwide says the safest response is often the simplest one: end the call, pause, and verify independently.
If something doesn’t feel right, trust your instincts — hanging up could save you from becoming the next victim.
