The holidays are a prime time for scammers, so individuals are urged to stay alert amid festive distractions.
are known to exploit those hunting for Christmas sale bargains or eager to secure concert tickets for the upcoming year.
On Christmas Day last year, victims reported online scams involving clothing purchases on Instagram, tickets for football matches and concerts on Facebook Marketplace.
Impersonation scams are also a significant risk, especially during the holidays when people spend more time at home.
On Boxing Day, several customers reported being targeted by scammers posing as their bank. Even New Year's Day brought no relief, with multiple advance fee scams reported. In one case, a customer paid £1,700 to a "recruiter" on WhatsApp, hoping to secure a job offer.
Data from Santander, spanning December 25, 2023 to January 1, 2024, showed the bank's retail and business customers reported a staggering 596 scams.
On Christmas Day alone, customers alerted the bank to 10 scams, amounting to £3,971.
The following day, Boxing Day, saw 25 scams reported, costing victims a hefty £45,788. New Year's Day was no different, with 24 scams reported, totalling £7,004.
Pete Staffel, Santander UK's behavioural scientist, warned: "Online adverts are the prime place for finding that dream present I even found one the other day, a perfect family game, complete with a video showing how it all worked. My kids would love it, and only two left in stock. But just before clicking buy, I checked the reviews, it was a scam."
He added: "Don't let the build up to Christmas cloud your senses. Scammers don't take the holiday season off, and whether it's through 'buy it now' ads, impersonating your bank, or offering a too-good-to-be- true investment, they will be looking for ways to be the Grinch that steals more than your Christmas."
