It took a pioneering role in the development of large scale renewables including the construction and operation of the UK's first offshore wind farm at Blyth in Northumberland.

[14][failed verification] This was merged with the distribution business of East Midlands Electricity and rebranded as Central Networks.

[17] 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.

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

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.

[29] After the acquisition of Npower in 2019, E.ON announced its bid to re-invent the business by launching E.ON Next, which has been built from the ground up as a new organisation and brand.

E.ON Next entered a strategic agreement with Octopus Energy Group to adopt the Kraken Technologies customer platform.

Former CEO Mike Lewis (succeeded by Chris Norbury in 2023) also revealed in an interview to BBC that they will migrate all existing E.ON customers to the new platform.

Due to sudden spikes in wholesale costs, an unusually high number of suppliers went out of business in 2021, resulting in several companies’ customers being migrated to supply with E.ON Next.

They also offer electric vehicle home chargers, energy efficient boilers, solar panel installations,[40] and heat pumps.

They also re-introduced their EV tariff, Next Drive,[41] in 2023, enabling customers to take advantage of lower overnight charging prices for their electric vehicles.

The company's headquarters are in Coventry at Westwood Business Park, in a building designed by Bennetts Associates.

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

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.
