E.ON UK (formerly Powergen) is an energy company in the United Kingdom and a subsidiary of E.ON, the world's largest investor-owned power and gas company. As Powergen, it was listed on the London Stock Exchange and was once a constituent of the FTSE 100 Index but since 1 July 2002[2] has been owned by E.ON SE of Germany.

It was formerly a vertically integrated utility company with interests in electrical generation, electricity distribution in the Midlands region, and in the electricity and gas supply markets. However, since restructuring and sales, E.ON UK is now a retail business with support functions.


Powergen was formed in 1989 as a Public Limited Company which was wholly owned by the UK government and acquired about 50% of the Central Electricity Generating Board generating capacity. Sir Robert Malpas was Chairman of the Group from 1989 to 1991.[3] Sixty per cent of Powergen was sold to private investors in 1991, followed by the remaining 40% in March 1995.[4] It expanded considerably by acquiring the regional electricity company East Midlands Electricity in 1998[5] and the supply business of TXU Energi in 2002.[6] Powergen was eventually taken over itself by E.ON, an acquisition which was completed in January 2002.[7]

It then bought the distribution network operator Midlands Electricity in 2004.[8] This was merged with the distribution business of East Midlands Electricity and rebranded as Central Networks.[9] The Industrial & Commercial Retail business was rebranded as E.ON UK on 5 July 2004.[10] The creation of the Central Networks business in April 2004 included "a company of E.ON" as part of its logotype. In October 2005 it was also added to the Powergen logotype.

In June 2007, a major advertising campaign entitled "The wind of change", containing advertisements using the E.ON logo, was launched. The campaign featured the Robin Rigg offshore wind farm in the Solway Firth, currently in development. In the consumer market, this was complemented by a replacement of the mostly blue Powergen identity to the red identity of E.ON, and the launch of a new product, Go Green, using electricity from renewable sources and carbon offset gas.

On 22 October 2007, the company announced that the E.ON Energy and Powergen brands would change to E.ON as of 1 November and 3 December 2007 respectively.[11]

In January 2008, E.ON acquired West Midlands-based CHN Group, a provider of heating services to builders, local authorities and housing associations across the region.[12] and in August 2008 completed the purchase of the Street Lighting business lighting projects of ABB Ltd. It intended to improve its existing lighting business by purchasing the ABB business.ABB.[13]

In 2008 and 2009 a number of protests took place at E.ON UK's power station including a Climate Camp at their Kingsnorth power station in August 2008[14] and at their Ratcliffe-on-Soar Power Station in October 2009.


On 20 January 2010, E.ON UK announced the closure of its Rayleigh Customer Service Centre and the loss of 600 jobs.[15] The company was forced to bring forward the announcement by one day after the information was leaked to a local newspaper. This has been criticised as a money-saving exercise by an organisation which has seen an increase in profits of 18% in 2009[16] and news that E.ON UK have made £80 million in profits so far in the financial year 2009/10. Other businesses within E.ON were also affected by these round of job losses, including its IT support and its Highways Lighting operations.

In March 2011, E.ON sold Central Networks to PPL's UK subsidiary Western Power Distribution for £3.5 billion.[17]

In October 2012, E.ON sold its 50% stake in Horizon Nuclear Power to Hitachi for £348 million. The other 50% stake, held by RWE npower, was also sold to Hitachi for the same amount, giving a total sale value of £696 million.[18]

Late in 2012, E.ON UK announced the closure of the 'Ignite' business, originally tasked with bringing alternative localised-generation products to market for E.ON UK.

In 2013, E.ON Home Energy Services was sold in a management buyout.[19]


The company's headquarters are in Coventry at Westwood Business Park, in a building designed by Bennetts Associates. There are numerous other offices and power generation sites across the country.

ITV National Weather

Powergen/E.ON sponsored the ITV National Weather forecasts from its launch on 13 February 1989 until 31 December 2007, a period of 18 years. They were known for their memorable sponsorship sequences from a set introduced on 5 April 1993 which featured weather themes circulating around (or parts of) the Powergen logo, and from 10 November 1996, the Weathergens, a "mascot" of Powergen representing different types of weather. After several different sets of idents throughout the 2000s, Powergen eventually became E.ON in 2007 and the sponsorship was changed to accommodate the name change. The sponsorship ended on 31 December 2007 and ITV National Weather is now sponsored by energy company SSE from June 2016 onwards (in Scotland by travel company Thomson).


In 2006, E.ON UK announced that it was to be the sponsor of the FA Cup for a four-year period. During this period, the competition is formally called "The FA Cup sponsored by E.ON". Before 2006, the company had sponsored the rugby union and rugby league cup competitions under the Powergen brand. The original four-year deal was extended to a fifth year as The FA failed to secure a new sponsor. The announcement was unpopular as it was made in the same week as the confirmation of closure of the Rayleigh Call Centre.

The company was the energy partner of the Football League, and sponsors the E.ON Lounge at the Ricoh Arena, the home of Coventry City F.C. Football Club.

In other sports, E.ON UK sponsored the Tour of Britain cycling championship from 2007 to 2009, and in 2007 launched a campaign with Ellen MacArthur to encourage energy efficiency within businesses.

Distribution network operators

E.ON UK is an energy supplier for homes across the country. They do not however manage the network of towers and cables that distributes electricity - these are maintained by distribution network operators (DNOs) which vary from region to region. If, for instance, there is a power outage it is necessary to contact the appropriate DNO rather than the energy supplier. See entry on distribution network operator for a full list.[22]
