Independent Gas Transporters (IGTs) develop, operate and maintain local gas transportation networks.
IGT networks are directly connected to the Gas Distribution Network (GDN) via a Connected System Entry Point or indirectly to the GDN via another IGT. Although domestic, industrial and commercial premises are connected to IGT networks, new housing and commercial developments form the largest share of the IGT market. It is estimated that the number of consumers connected to IGT networks is around one million.
