2026’s Leading Open Banking Data Providers in the UK

Open banking data refers to the secure, consent-based sharing of customer bank account data between financial institutions and authorised third-party providers via APIs.

In the UK, this ecosystem is regulated by the FCA and has grown to over 13 million active users, with 14 billion API calls processed annually (Open Banking Limited, 2025).

Five providers dominate the UK open banking data landscape in 2026. Each has a distinct focus – on geography, use case, and data depth. Choosing the right one depends on whether you are building for the UK specifically, across Europe, or globally.
