Industry codes and standards
About industry codes
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.
The codes
The table below lists the industry codes and their administrators.
The Code Administrators have developed a Central Modifications Register which details all current modifications across the codes. This spreadsheet is managed by the Code Administrators and updated by them monthly.
We publish our decisions relevant to each code in Industry code publications: code decisions and notices.
In addition to the codes
- Distribution Network Operators are required to provide a Data Transfer Service (DTS) to facilitate the electronic transfer of certain industry data - for more information see the Electralink DTS website.
- Xoserve Limited provides a range of services to support the GB gas industry, for example billing services and managing and booking of capacity. Further information on the services is available on the Xoserve website.
- Following Retail Code Consolidation, on 1 September the Master Registration Agreement, Supply Point Administration Agreement, Green Deal Arrangements Agreement, and Smart Meter Installation Code of Practice were consolidated into the Retail Energy Code.
Expected decision dates
This table provides the Expected decision date (EDD), or the date we intend to publish an impact assessment or consultation, for code modifications or proposals that are with us for decision. The table also identifies the responsible Ofgem team.
Documents relating to each code modification or proposal are available on the relevant code website listed above.
The dates set out in the final column of the table (Expected date of decision) reflect our expectations as of the date this version of the table is published. These dates may change (for example, due to developments in respect of a particular modification proposal or due to other changes in priorities). Any changes in Ofgem’s expectations will be reflected in updated versions of this table, which will be regularly published on our website.
