Nationwide Building Society has issued a warning about a letter going out to its members. The issue came to light after a customer asked the group about a letter they had received. They shared an image of the letter which was entitled ‘Exclusive Fixed Savings Offer in Collaboration with Raisin’.

The message spoke about some fixed term savings accounts and fixed cash ISAs that Nationwide was offering in collaboration with savings provider Raisin, and provided an email where the person could respond to if they were interested.

However, the person was concerned the message was fake. They asked Nationwide: “We just had this letter in the post – is this legit? Looks like done on laser printer, no sign of “Raisin” FCA firm, ref number etc. Screams scam to me.”

In response, Nationwide confirmed the letter was not from them. The provider said: “Just to confirm that this isn’t an official letter from Nationwide, we will send this onto our Economic Crime team for their awareness.”

The bogus letter reads:

“Dear Valued Customer,

We are pleased to bring you an exclusive opportunity. As a valued customer of Nationwide Building Society, you now have access to a limited time offer on fixed savings products through a direct collaboration with Raisin.

The letter also included a ‘Product feature sheet’ with details about the fake savings schemes. Some common telltale signs the letter may be fake include that the letter is generalised in being addressed to a ‘valued customer’ rather than addressing the customer by name.

Unfortunately scammers sometimes can get these personal details and will address you by your name. Warning of a ‘first-come, first-served basis’ and the looming deadline date is also a classic tactic, to try and hurry you into making a decision.
