FUTURE IGT UNC RELEASES

Friday 8th November 2019

PAST IGT UNC RELEASES

Previous versions of the IGT UNC, Ancillary Documents or a full release history can be provided on request to the IGT UNC Code Administrator.

The IGT UNC was implemented on the 1st of May 2007 following designation by the Gas and Electricity Markets Authority. The IGT UNC was implemented to streamline and harmonise the network code arrangements of the IGTs as much as possible. However, IGTs will still maintain their own network codes for those requirements that are not covered by the IGT UNC. If you require information or assistance in relation to the network code of an IGT please look under the IGT UNC and Related Documents tab. More information about the IGTs can be found in the ‘Who are the IGTs’ section of the website.

From this page you can download the latest version of the IGT UNC and the Transition Document.
