The Change Process

The role of the Panel is to consider changes that have been raised, and recommend to the Authority whether these proposed changes should be implemented in the market codes.

MOSL, in its role, supports the change process by establishing working groups and managing consultations on the instruction of the Panel. We encourage parties that are considering raising a change to contact MOSL in advance so that we can support the Proposer develop the change.

Raising a Change

To raise a Change for the Panel to consider, please contact with your Change Proposal, using the templates provided in the Related Documents section at the bottom of this page.

When raising a change please be aware of the Change Timetable, which sets out the deadline for when a change proposal needs to be raised in order to be considered at the next Panel meeting.

What happens next? Once a change has been raised, the formal process is:

Change Register

The Change Register is a new standalone register containing information on all the change proposals raised, past or present.

All information relevant to each Change Proposal, such as the original proposal, Assessment and Recommendation Reports, Industry Consultations and Working Group papers and minutes, are accessible via tool below, which provides a life-cycle view of the change.

In addition to the Change Register, you can also track a change via the Panel Change Proposal Log.

If you have any questions in relation to this new feature, please contact the Panel Secretary.
