Industry codes

The industry codes underpin the electricity and gas wholesale and retail markets. Licensees are required to maintain, become party to, or comply with the industry codes in accordance with the conditions of their licence.

Code Administrators are the point of contact for each code where users can find out information about that code, including how to become a party to the code (if appropriate) and the rules on modifying the code. Code Administrators have committed to operating their code administration functions in accordance with the Code Administration Code of Practice (CACoP).

Code Administrators, as part of their role, act as Critical Friends to code users. The role of the Critical Friend is described in CACoP as a Code Administrator who provides support to all with an interest in the code modification process and consumer representatives. The Code Administrators have identified a list of the Top 5 activities of a Critical Friend.

The Code Administrators have developed a Central Modifications Register which details all current modifications across the eleven codes. This spreadsheet is managed by the Code Administrators and updated by them monthly.

The codes define the terms under which industry participants can access the electricity and gas networks. The table below lists the codes and contact details for them.
