Information relating to gas connections (ICPs) and gas consumption is routinely exchanged between gas market participants for a variety of reasons. Files are also exchanged between central IT systems such as the gas registry and gas allocation system as part of the orderly functioning of the gas market.

Specifying and standardising the format for information exchange creates efficiencies and allows participants to automate the production, transmission and receipt of information.

In 2010, Gas Industry Co appointed the Information Exchange File Formats Working Group (IEFFWG) to create file formats required under governance arrangements, propose changes to existing file formats and develop further protocols for exchanges of information between industry participants. There are currently four GIEPs, which can be found below.

While the file formats are not mandated under any regulatory arrangements, they are provided as a guideline, in order to support improvement of industry practices.
