Treasury committee finds disruption a result of 158 IT incidents affecting millions of customers

Customers at Britain’s major banks and building societies suffered the equivalent of more than one month’s worth of IT failures in the last two years, MPs have said.

Enquiries by the House of Commons’ Treasury committee have found that nine of the top banks and building societies operating in the UK accumulated a total of at least 803 hours, the equivalent of more than 33 days, of unplanned tech and systems outages between January 2023 and February 2025.
