MP161 Significant Code Review – Retail Code Consolidation

Proposer The Authority
Lead Analyst Joe Hehir
Date raised 05/05/2021
Implementation date 1 September 2021 (Ad-hoc SEC Release)
Latest update On 2 July 2021, the Authority approved this modification.

What is the issue?

Ofgem launched the Retail Code Consolidation Significant Code Review (SCR) in November 2019 to make faster, more reliable switching a reality for consumers and to harmonise, as far as is sensible, the provisions for switching in gas and electricity. To facilitate this aim, the SCR will rationalise retail energy Codes. The Retail Code Consolidation SCR scope also covers improvements to cross-Code change management. This is due to be achieved through the introduction of a Cross Code Steering Group under the REC, and modifications to the other relevant Codes to embed a new process for managing cross-code changes.

Whilst the majority of the changes do not affect the SEC, cross references within the SEC to Energy Codes that are being consolidated into the REC need to be updated. Equally, the new provisions for how to better coordinate the progression of cross-Code changes need to be introduced.

What is the solution?

This modification will amend a number of refences to other Energy Codes alongside the SCR to ensure consistency between all the impacted Codes.

Additionally, it will introduce a new framework for progressing cross-Code modifications. The amendments will require the SEC Panel to nominate representatives to a new Cross Code Steering Group who will help coordinate and progress cross-Code issues. It also sets out the concept of Lead Codes and Consequential Changes and allows the Panel to appeal decisions on such changes to the Authority where appropriate. The intent is to ensure better coordination of cross-Code issues and the progression of related changes as a suite rather than piecemeal and staggered change.

Who is impacted?

The changes to the SEC resulting from the SCR will not directly impact SEC Parties, nor will it impact the DCC.

Other industry Codes will also be affected:
  • Balancing and Settlement Code (BSC)
  • Distribution Connection and Use of System Agreement (DCUSA)
  • Independent Gas Transporter Uniform Network Code (IGT UNC)
  • Master Registration Agreement (MRA)
  • Supply Point Administration Agreement (SPAA)
  • Uniform Network Code (UNC)
