fuel mix disclosure
All licensed suppliers are required to publish information on the mix of fuels used to produce the electricity they supply and the environmental impact of its generation.
39% of our total supply from April 2010 to March 2011 came from renewable generation – compared to the UK average of 7.9% and significantly higher than all of the ‘Big Six’ energy suppliers.
The information below details the mix of fuel sources used by SmartestEnergy from April 2010 to March 2011.

SmartestEnergy is able to meet the growing demand from businesses and organisations to meet some or all of their energy needs from environmentally-friendly sources.
