Triodos Bank UK
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.
Triodos Bank UK publishes 10 API contracts indexed on the APIs.io network, including Account Information Service API, Authorization Endpoint API, Client Registration Endpoint API, and 7 more. Tagged areas include Financial Services, Banking, Open Banking, PSD2, and XS2A.
The Triodos Bank UK catalog on APIs.io includes 1 Spectral governance ruleset.
Triodos Bank UK’s developer surface includes authentication, sandbox, changelog, API reference, signup flow, documentation, getting-started guide, and 28 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Consumer Lending Licensing (UK, US, Canada credit licence registers) | regulated | 19.2 (thin) | - | - |
| EU/EEA Payment and E-Money Institutions (PSD2 passports) | regulated | 19.2 (thin) | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
