Fraud worth £820m was stopped in the first half of 2019, up 14% on the previous year, according to the latest figures from UK Finance.

Data from the UK financial trade body UK Finance has revealed that a total of £503.4 million was stolen by criminals through authorised and unauthorised fraud in the first six months of 2018.

The Financial Ombudsman Service has told banks they should take into account the “evolution and sophistication” of frauds and scams – and not simply assume that their customers were “grossly negligent.”
