Acquisition of TSB
Santander UK completed its acquisition of TSB Bank plc on April 30, 2026, having received approval from the Prudential Regulation Authority and the European Central Bank. TSB continues to operate as a separate bank under its own brand while its business and assets are formally transferred to Santander UK, a transfer that remains subject to legal and regulatory approvals. TSB Bank plc is still separately authorised, appearing alongside Santander UK plc on the Bank of England’s List of PRA-regulated Banks as at August 1, 2026.
The branch network has continued to contract: a further 66 branches are closing in phases from April 2026. Beyond those closures, Santander has said it does not intend to close any additional TSB or Santander UK branches before 2028 at the earliest.
