Dear Third Party Provider,

This is an advance notification of an upcoming change to our Open Banking service provision.
From August 2026, we will be transitioning to a new service provider responsible for supporting our Open Banking interfaces and related connectivity services. This change will apply to all TPPs accessing our Open Banking APIs.
Detailed information, including:

• migration approach and timelines
• technical specifications
• testing and readiness requirements
• actions TPPs must take to avoid any interruption to service

will be published on our Developer Portal at https://developer.mhbkemea.co.uk
Please note that TPPs should not take any migration-related actions until the detailed guidance is published.
We will continue to provide updates ahead of the effective date to ensure a smooth and orderly transition. 
If you have any questions, please contact our Support Team.
