The board of TSB has been accused of a lack of “common sense” in the run-up to IT failures that left up to 1.9 million customers unable to bank online, some for several weeks, in April 2018.
An independent report into the incident by law firm Slaughter and May blamed both TSB and IT provider Sabis.
Customers were moved on to a new system, but the report said it had not been tested properly before going live.
It found that the tests only took place offline and not in a live environment.
It said that TSB accepted that had tests been run across both systems, it might have been able to identify the issues which affected customers before they happened.
“We have concluded that the new platform was not ready to support TSB’s full customer base and Sabis was not ready to operate the new platform,” the report said.
“” While the TSB board asked a number of pertinent questions … there were certain additional common sense challenges that the TSB board did not put to the executive.
“These included why it was reasonable to expect that TSB would be ‘migration ready’ only four months later than originally planned, when certain workstreams were as much as seven months behind schedule.”
The report also said that there were more than 2, 000 defects relating to testing at the time the system went live, but the board were only told about 800.
Other failings by TSB that it identified included setting “unnecessary” time constraints, which did not understand the complexity of the project, and being dishonest about the causes for delays.
TSB is part of the Spanish banking group Sabadell and its in-house IT provider Sabis built the system .
The IT failure has cost TSB a total of £ 370 m for customer compensation and to cover expenses for the inquiry by Slaughter and May.
‘A complete demolition of trust’
The IT fiasco at TSB left many thousands of customers in difficulty, calls were unanswered for 90 minutes and fraud attacks were 70 times higher than usual levels at their peak, the report reveals.
Among those affected was photographer Paul Clarke, who could not use his accounts and was defrauded in the confusion. He says he left the bank as soon as was reasonably possible.
“After the fraud, there was a complete demolition of trust,” he says. “I was left for two weeks without being able to function financially.”
He was annoyed about the fraud, although the money was later refunded , but more so about the response from TSB to the situation.
He described the failures of the IT switchover as “basic stuff”.
The timing of the IT mess could not have been worse for Sally and Chris Jones – TSB mortgage holders – whose house move turned into24 hours of chaos.
“It was terrible timing for us, that they were not ready [with the IT switchover],” says Mrs Jones.
Problems at TSB meant funds were not released so they were stuck in limbo, waiting outside their new home in a removals van, facing the prospect of staying overnight in a hotel.
“It was all very
Eventually they got inside, but there were still problems with completing the purchase and early in the mortgage term. They were compensated and have not had problems since, so have remained as customers.
TSB executive chairman Richard Meddings said: “Slaughter and May’s report sets out a number of findings on aspects of the planning and preparation for migration which they believe could have been done differently.
“In light of the disruption customers experienced, TSB has made important changes to enable the bank to rebuild – including to leadership and management structures, as well as the decision to take direct control of its IT operations.
“Importantly, TSB has long since compensated every eligible customer who was impacted by the disruption.”
TSB’s former chief executive Paul Pester,who quit his job a few months after the incident,said: “If these findings are right , Sabis rolled the dice by running tests on only one of TSB’s two new data centers and this decision was kept from me and the rest of the TSB board.
“The report explains that this made it impossible for the TSB board to anticipate the serious problems experienced by many customers who could not access their accounts.
“Obviously, if we had been aware of Sabis’s shortcuts in the testing program, the TSB board and I would never have pressed ahead with switching to the new system at that time.”
The Slaughter and May report was commissioned by TSB. Another joint report by two regulators, the Financial Conduct Authority and the Bank of England’s Prudential Regulation Authority, will be published at a later date. Those regulators have the power to fine and reprimand businesses and individuals.
