More than 900 jobs will be lost as high street bank TSB announced plans to shut more than a third of its branches.

The bank will shut 164 sites, with locations of the branches due to be announced this afternoon.

The moves - which will mean TSB will have more than halved its estate over the past seven years - have come with the Spanish-owned bank saying the cuts have been driven by a “significant shift in customer behaviour”, as fewer customers use branches in favour of online banking.

The company has previously said it intended to reduce the size of its branch network but has now accelerated plans amid the pandemic.

It will leave the bank with 290 branches, more than halving its store estate over the past seven years.

Debbie Crosbie, chief executive of TSB, said: “Closing any of our branches is never an easy decision, but our customers are banking differently - with a marked shift to digital banking.

“We are reshaping our business to transform the customer experience and set us up for the future.

“This means having the right balance between branches on the high street and our digital platforms, enabling us to offer the very best experience for our personal and business customers across the UK.

“We remain committed to our branch network and will retain one of the largest in the UK.”

Dominic Hook, Unite national officer, said: “Unite has urged the bank to rethink these plans and protect these much-needed jobs during the current health pandemic.

“Not only do these staff deserve more from their employer after showing the utmost loyalty to TSB, customers will be deeply hit by these branch closures.

“Unite has argued for some time that the financial services industry has a social responsibility not to walk away from its local customers, who continue to need access to banking in bank branches.”

TSB said the branches earmarked for closure have been selected to ensure 94% of its customers could travel to a branch in 20 minutes or less.
