Vickie Sheriff, director of campaigns and communications at Which?, said: ‘These statistics show the staggering number of people who have fallen victim to fraud, and with scams becoming ever more sophisticated, it’s clear that the government, regulators and businesses need to do much more to protect consumers.
‘We know that people can lose life-changing sums of money through bank transfer fraud and they currently have no legal right to get their money back from the banks.
‘With so much fraud unreported, unrecorded and undetected, this needs urgent attention.’

Increasing diversity of scams
Fraud and computer misuse crimes were included for the first time in this annual report, which looked at the incidence rates and numbers of offences for a year ending September 2016.
The most common types experienced were bank and credit account fraud followed by non-investment fraud, which includes scams related to fraudulent computer service calls or online shopping.
Which? has seen an increase in the number of non-investment frauds reported recently, including an Amazon scam email going after bank details and a scam targeting Scottish Netflix users to update membership details.
Frauds referred to police increased by 3% year-on-year, while industry data showed cases on UK-issued cards jumped by nearly two fifths to 1.9m.
