Strategic Focus on TSB Integration and Market Positioning
These leadership changes underscore Santander UK’s strategic priorities amid the TSB integration, which significantly expands its UK retail banking footprint.

By combining internal promotions and external hires, Santander UK balances continuity with fresh expertise to strengthen governance and accelerate integration. The organisational realignment aligns Santander UK’s structure with Banco Santander’s governance and operational frameworks.
Banco Santander Group’s Global Scale and Structure
Santander UK operates as a subsidiary of Banco Santander, a global banking leader founded in 1857 and headquartered in Spain. Banco Santander manages five global business segments: Retail & Commercial Banking, Openbank, Corporate & Investment Banking, Wealth Management & Insurance, and Payments, leveraging global scale with local market leadership.
As of Q1 2026, Banco Santander reported 1.4 trillion in total funds, over 176 million customers, 6,600 branches, and 185,000 employees worldwide. Santander UK’s integration into this global network enhances access to capital, expertise, and operational capabilities, particularly in payments, supported by Perkins’s leadership and the group’s strategic focus.
Regulatory Approval and Transition Timeline
Tom Ranger’s CFO appointment and Michael Christodoulides’s Chief Compliance Officer role are subject to regulatory approval, effective 1 October 2026 and 1 November 2026 respectively. Steve Affleck’s promotion to Chief Accounting Officer is effective immediately as an internal advancement. Angel Santodomingo will remain CFO until 31 October 2026 to ensure a smooth handover.
