What are IGT tariffs?
An IGT tariff is one where your gas supply is delivered to your home by an Independent Gas Transporter, rather than the National Grid Gas. According to energywatch, 760,000 gas consumers (equal to 3% of all gas consumers) are currently connected to one of the networks operated by an Independent Gas Transporter. The number of IGT network connections is however increasing rapidly and the industry regulator Ofgem estimates that 1 million homes and businesses will be connected to an IGT by 2008.
