MRA Change Release Information

There are three scheduled releases of the MRA and its products in each calendar year as per MAP17. These are on the last Thursday of February and June, and the first Thursday of November. Further extraordinary releases can be scheduled if the need arises. Due to the impending implementation of the Retail Energy Code (REC) in September 2021, there will be no further MRA releases after June 2021, unless agreed by Ofgem. To allow for changes to the MRA to be taken into consideration under the REC, no Change Proposals (CPs) can be voted on after 25th February 2021.

The planned MRA release dates for 2020/21 are as follows:

  • 5th November 2020
  • 25th February 2021
  • 24th June 2021

To view all Change Proposals and their current Status related to a specific release date, please filter on Implementation Date in the MRA Change Tracker.

If you have any questions, contact the MRA Helpdesk.

ECOES Release Management

Changes to ECOES are governed through the MRA Change Process set out under MAP17. These changes are aligned to wider industry change programmes and are generally released three times per year, in the months of February, June and November.

The latest version of the ECOES industry release notes support any changes parties may need to make to align their system with the general ECOES release.
