Santander UK Faces Overhaul: New Boss, Branch Closures Post-TSB Deal
5 Jan
Summary
- Santander UK's CEO will depart by March 2026 after the TSB acquisition.
- TSB acquisition by Santander UK is expected to lead to branch closures.
- A car finance scandal has impacted Santander UK's recent financial reporting.

Santander UK is preparing for a period of substantial change, marked by the upcoming departure of its chief executive, Mike Regnier, by March 2026. This transition occurs in the wake of Santander's £2.65 billion acquisition of TSB. Regnier acknowledged that the integration of TSB, which is expected to see the TSB brand disappear from high streets, will likely involve branch closures and job losses. The responsibility for managing this complex merger will fall to his successor.
Two internal candidates, Mahesh Aditya and Enrique Alvarez Labiano, are reportedly in contention for the leadership role. Beyond the merger, the new chief will also need to address the ongoing repercussions of a car finance scandal that has affected numerous lenders and prompted Santander to postpone its third quarter UK results. This scandal involves an £11 billion compensation scheme for mis-sold car loans, a scheme Santander has criticized.
The TSB acquisition, completed in the summer, positions Santander UK as the third-largest bank by current account balances and fourth by mortgages, serving 28 million customers. The merger is projected to reduce combined operational costs by 13%, primarily through efficiencies in IT and back-office functions, signalling a significant consolidation of branches where overlap exists.
