This dataset contains information on the evolution of major electricity tariffs by the 6 biggest electricity suppliers in Great Britain. Data is available for the 14 energy regions separately between 2005 and 2013. The ESRC Centre for Competition Policy (CCP) at the University of East Anglia (UEA) undertakes interdisciplinary research into competition policy and regulation that has real-world policy relevance without compromising academic rigour. It prides itself on the interdisciplinary nature of the research and the members are drawn from a range of disciplines, including economics, law, business and political science. The Centre was established in September 2004, building on the pre-existing Centre for Competition and Regulation (CCR), with a grant from the ESRC (Economic and Social Research Council).

The dataset was collected through information from Energywatch (2001-2008) and Consumer Focus (2009-2013).The underlying data being sourced from www.uswitch.com (2001-2006), www.switchwithwhich.co.uk (2007-2009) and www.energylinx.co.uk (2010-2013). This was then compiled into the electricity tariff dataset.
