“Can the UK's largest mutual building society modernise its core payments and digital onboarding infrastructure fast enough to retain members against challenger bank competition?”
Nationwide is the UK's largest building society, a member-owned mutual operating as a full-service retail bank offering current accounts, mortgages, savings, insurance, and personal loans. Unlike shareholder-owned banks, profits are returned to members. In recent years, Nationwide has invested in modernising its technology infrastructure — partnering with Form3 for payments and Jumio for digital KYC — reflecting a broader push to compete with challenger banks on digital onboarding and payment speed while retaining its mutual ethos.
Nationwide processes payments through Form3 (payments infrastructure).
Nationwide uses Jumio for KYC and identity verification.
Nationwide connects to bank accounts through Yapily.
The Embedded Finance Index 2026 maps 4 layers in Nationwide's stack: Payments / PSP (Form3 (payments infrastructure)); Lending (Personal loans, Mortgages and FlexPlus account overdrafts); Open banking (Yapily); KYC (Jumio).
Nationwide is founded in 1846 and headquartered in Swindon, United Kingdom.
