It was developed to inform consumers about the ability to switch electricity and gas companies, the ease of switching and the potential savings they can make on their energy bills by switching.


Compare gas contracts

Gas Industry Co administers a Retail Gas Contracts Oversight Scheme that helps consumers evaluate retailers’ publicly posted supply terms and conditions.  Since its introduction in 2010, the Scheme has prompted a significant improvement in the clarity of those arrangements.

Reviews are undertaken by an Independent Assessor with the most recent full review in 2018. Gas Industry Co aims to conduct full reviews at three yearly intervals.

The assessment details the contract alignment rating, and you can compare the results for individual retailers which are summarised as follows.


Average alignment

Genesis Energy




Nova – Residential

This table shows the level of alignment on a scale of full (being the best), substantial, moderate, low and none (being the worst) for each gas supply arrangement against each benchmark in 2018.
