MHHS Webinars & Open Days


MHHS Open Day: 25 March 2025

Thank you to everyone for coming to our MHHS Open Day  on 25 March 2025. We were delighted that over 200 people were able to join us, either in person or virtually. The day was a big success, with engaging sessions and lots of questions asked throughout the day.   

The focus of this Open Day was to build a shared understanding of Programme and participant readiness for Milestone 10 (M10) and beyond. The Programme provided an overview of key activities that need to happen to reach M10 and clarified what is required of participants beyond M10 as we move into the new arrangements.  

If you couldn’t make the Open Day, or you want to remind yourself of some of the content, you can view the presentation slides below:
