Previous Circular

On 4 August 2021 we published MDD Circular 00744.

MDD Circular 00744 details the changes that the Supplier Volume Allocation Group (SVG) approved to be incorporated into Version 314 of MDD.

It also details the MDD changes related to Ofgem’s Targeted Charging Review (TCR) that the SVG approved to be incorporated into Version 315 of MDD. These have been approved a month in advance, to facilitate the extra time required to process the large volume of TCR changes.

All MDD Circulars
