Tandem Bank
Tandem Bank (Tandem Bank Limited) is a UK app-only challenger and self-styled "greener" digital bank founded in 2014 and headquartered in Blackpool, England, with offices in Cardiff, Durham, and London. It obtained its UK banking licence through the 2018 acquisition of Harrods Bank and has since grown by acquiring Allium Lending Group, Oplo, and Loop Money, offering savings and cash ISAs, green home-improvement and home loans, mortgages, motor finance, and a credit card. Tandem Bank Limited is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority. It is not one of the CMA9 and does not publish a public Open Data reference API; as an FCA-authorised ASPSP it meets UK Open Banking / PSD2 obligations through a dedicated interface provided by Token, conformant to the Open Banking Implementation Entity (OBIE) Read/Write Standard for Account and Transaction Information (AIS), Payment Initiation (PIS), and Confirmation of Funds (CBPII), secured with FAPI-grade OAuth2/OIDC, mutual-TLS, and PSD2 strong customer authentication. Tandem also consumes Open Banking as a TPP via TrueLayer for savings onboarding and transfers.
Tandem Bank publishes 28 APIs on the APIs.io network, including Account Access Consents API, Accounts API, Balances API, and 25 more. Tagged areas include Financial-Services, Banking, Open Banking, PSD2, and OBIE.
Tandem Bank’s developer surface includes authentication, getting-started guide, engineering blog, support, and 24 more developer resources.
