In 2000, the Social Action Strategy review group was established and the Competition Act came into force. In 2003 the Wholesale Gas Probe was published. Two years after the removal of the last price controls, in April 2004, Ofgem published a major review of the state of competition in the domestic energy supply markets, concluding that supply competition had delivered substantial benefits for all consumers and that the markets were competitive, though not yet mature. In 2005 there was the EU Energy Sector Enquiry, as well as the Supply Licence Review. The Energy Supply Ombudsman was then established in 2006 and in 2008 the Energy Supply Probe was published.
