Simon Virley was director general for 'energy markets and infrastructure group' in the Department of Energy and Climate Change (DECC), leading the UK government’s work on on renewables, nuclear, oil and gas, shale, carbon capture and storage, and UK energy security issues from September 2009 until January 2015.
In a classic case of the revolving door between politics and business, Virley left the civil service to take up the role of chair of energy and natural resources at KPMG UK in February 2015. He had previously worked for the Big Four firm on secondment from 2005-08.
According to KPMG, Virley led the biggest reforms to the UK energy market since privatisation. 
Between 2000-03 he was private secretary to Tony Blair while he was prime minister, and dealt with economic affairs. He then lead the cross-departmental work on better regulation as director of the Better Regulation Executive (2003-05), before a secondment at KPMG where he was director of corporate finance, advising on the financing of energy and other major infrastructure projects. 
He was also a temporary joint chair of the Electricity Strategy Network Group.
