Mike Regnier, Chief Executive of Santander UK, has announced plans to step down by the first quarter of 2026 after nearly four years leading the bank through a major period of transformation.
Santander UK CEO Mike Regnier to Step Down by Early 2026
Regnier joined Santander UK in March 2022 and is said to have played a central role in reshaping the business, including the bank’s acquisition of TSB Banking Group from Banco Sabadell, which is awaiting regulatory approval.
A process to appoint his successor is already underway.
“It is my intention to step down as CEO of Santander UK by Q1 2026 after what will be four years of great strategic success for the business,” Regnier said.
He added that the integration of TSB “will take time and focus,” so now is a good moment for the bank to find a successor “who can see this critical project through to completion.”
Ana Botín, Executive Chair of Banco Santander, praised Regnier’s leadership, saying he had “done an excellent job” and that the TSB deal “accelerates our strategy and is a clear statement of intent in our ambition for Santander in the UK.”
Tom Scholar, Chair of Santander UK, added that the board expects to conclude the appointment process early next year, ensuring leadership stability during a “period of intense change and opportunity.”
Regnier’s departure will mark the end of a tenure that saw Santander UK push towards a more unified, customer-focused banking model integrated within the global group.
