MDD Release Schedule

The MDD Release Schedule highlights the key dates for each Version of MDD. Following the implementation of CP1271 ‘Align Market Domain Data Approval Timetable to SVG meetings’, the dates for each Version are based around the dates of each Supplier Volume Allocation Group (SVG) meeting. In addition, there is a second ‘Fast Track’ schedule for New Entrants, allowing them to submit their forms closer to the SVG meeting. The MDD Release Schedule for the following year will be issued in a Circular towards the end of the current year.

When should the ‘Fast Track’ process be used?

The ‘Fast Track’ process can only be used for a specific criteria: New Green Deal Entrants, ‘House Keeping’ and New Suppliers/Supplier Agents who need to register Role Codes, Company Names and Address details.

The Change Request Deadline date is the last date that we can consider Change Requests for a particular version of MDD. Any Change Requests received after this date will be incorporated into the following MDD Release. The Publish and Go-Live dates of each Version of MDD are also given.

MDD Change Request Dates for 2016 – 17

Note: Please ensure all Change Requests (including Fast Track Change Requests) are submitted by 5pm (17:00) on the day of the deadline.
