The story

Santander UK plc is the UK arm of global banking group Banco Santander, operating as a separately capitalised and regulated entity since 2010. It has progressively built out its embedded finance capabilities for business and corporate customers — partnering with Worldpay for merchant acquiring (2025), AirPlus for corporate cards and spend management, and with Allianz Trade and Two for B2B BNPL (2023). Its developer portal exposes Open Banking-compliant APIs (AIS/PIS) as a CMA9 obligated bank, making it both a consumer of and infrastructure provider to the open banking ecosystem.
