Open Banking offers a secure and regulated way to share your financial information with trusted providers. It allows you to give law firms instant access to the data they need to verify your source of funds - eliminating the need to download bank statements or send sensitive documents by email.
The Open Banking Directory, maintained by Open Banking Limited (OBL), lists all regulated providers participating in this ecosystem.
As of April 2025, there are 91 Account Servicing Payment Service Providers (ASPSPs) enrolled in the Open Banking Directory. These include a diverse range of institutions, from major high street banks to challenger banks and specialised financial entities.
