Since the introduction of the Retail Gas Contracts Oversight Scheme, five assessments have been conducted: a baseline assessment in 2010, a 'transitional' assessment in 2011, and full assessments in 2012, 2015 and 2018.
Simpson Grierson was the Independent Assessor appointed by Gas Industry Co to conduct the 2018 assessment. Previous assessments were carried out by Elwood Law and Roger Palairet of Palairet Law.
