aid: hampden-and-co url: https://raw.githubusercontent.com/api-evangelist/hampden-and-co/refs/heads/main/apis.yml name: Hampden & Co kind: company description: >- Hampden & Co (trading as Hampden Bank since March 2024) is an independent UK private bank headquartered at 20/21 Charlotte Square, Edinburgh, with offices in London and Manchester, serving high-net-worth individuals, their families, and their businesses with day-to-day banking, deposits, and specialist lending. Incorporated in 2010 as "Scoban" and launched in 2015, it was the first newly created UK private bank in three decades; it is a shareholder-owned public limited company (SC386922) - not a mutual or building society - backed by cornerstone shareholders and hundreds of smaller investors, and passed £1 billion in deposits in 2025. It is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the PRA. Although not one of the CMA9 mandated banks, Hampden & Co is an FCA-authorised ASPSP registered with the Open Banking Implementation Entity (OBIE) and exposes a PSD2 dedicated interface: an Open Data reference API plus the OBIE Read/Write family (Account & Transaction Information, Payment Initiation, and Confirmation of Funds), onboarded through a developer sandbox portal and secured with FAPI-grade OAuth2/OIDC, mutual-TLS, PSD2 strong customer authentication, and eIDAS/OBIE certificate-based dynamic client registration. accessModel: pricing: unknown onboarding: partner trial: false try_now: false public: false label: TPP onboarding · eIDAS/OBIE certificates required confidence: medium source: - authentication - onboarding generated: '2026-07-23' method: derived image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Financial Services - Banking - Private Banking - Open Banking - PSD2 - OBIE - FAPI - United Kingdom - Payments - Account Information created: '2026-07-23' modified: '2026-07-23' specificationVersion: '0.19' apis: - aid: hampden-and-co:hampden-and-co-open-data-api name: Hampden & Co Open Data API description: Public, unauthenticated Open Data reference API conforming to the OBIE UK Open Banking Open Data standard (product reference data such as personal and business current accounts).
