A new ResPublica publication reveals that businesses looking to become energy suppliers face major barriers to entry in the UK. 12 new businesses have entered into the domestic supply market since 2011, taking the total number to 25, but the six largest energy companies still capture 93.5% of the market share. In stark contrast, Germany is home to 1100 electricity suppliers, and the four largest energy businesses hold only 44% of the retail market. Households in Germany can choose from an average of 72 energy suppliers, most of which are established locally. The ResPublica Essay, ‘Creating Local Energy Economies: Lessons from Germany’, which is supported by the Winston Churchill Memorial Trust and Co-operative Energy, argues that the UK can deliver on greater transparency, lower household bills and genuine competition if communities, local authorities, housing associations and small businesses could enter into the supply market and sell their energy locally. At present, there are no local suppliers in the UK.
