description: Triodos Bank UK Limited is a values-based, sustainability-focused bank headquartered in Bristol, England, and
  the UK arm of Triodos Bank N.V. (founded 1980, Netherlands), one of Europe's leading ethical banks. Ownership of the parent
  sits with the SAAT foundation (Stichting Administratiekantoor Aandelen Triodos Bank), which issues depositary receipts rather
  than tradable shares, so Triodos is neither a conventional listed plc nor a customer mutual; it is a certified B Corporation
  that lends only to organisations delivering positive social, environmental, and cultural impact. Triodos Bank UK Ltd (company
  no. 11379025) is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and
  PRA (FRN 817008). As an FCA-authorised ASPSP it meets UK Open Banking / PSD2 obligations, but - unlike the CMA9 - it is
  a specialist lender that implements the Berlin Group NextGenPSD2 (XS2A) standard rather than the OBIE UK Read/Write standard,
  publishing a single developer platform at developer.triodos.com covering its UK, Netherlands, and Belgium account holders.
  Its production XS2A APIs provide Account Information (AIS), Payment Initiation (PIS), and Confirmation of Funds (CoF) services,
  secured with OAuth2/OpenID Connect authorization, mutual-TLS client authentication, eIDAS/QWAC certificates, and PSD2 strong
  customer authentication, with a full sandbox for onboarding and testing.
