Platform status

Our aim has always been to upgrade you and your clients safely and with minimal impact. To help us to do so, we asked a select group of James Hay users to place new business on the new platform ahead of the upgrade, and we carried out four dress rehearsals with thousands of tasks replicated.  

However, should you come across any issues, please inform your usual point of contact. We value your feedback and will work to resolve any problems as quickly as possible.

Information regarding any current known issues is published within the platform, ensuring transparency and awareness.
