E.ON is one of the UK’s best-known energy suppliers which provides businesses across the nation with electricity and gas, as well as other services. E.ON has split into two brands for their business energy customers. E.ON next serves SME customers with a digital focus and the classic brand offers business solutions for higher consumption.

The supplier is a subsidiary of the German company E.ON SE, one of Europe’s biggest electricity providers. The name E.ON comes from the Greek word ‘aeon’, which means age.

One of the UK’s ‘Big 6’ energy suppliers, E.ON currently supplies gas and electricity to approximately 3.8 million customers across the UK, making them one of the country’s leading energy providers.

Based in Coventry but with subsidiary offices, including a customer services department in Nottingham, across the UK, the company was previously known as Powergen. Powergen was acquired by EON (created in 2000 in Germany)  – and subsequently renamed in 2002.

A Guide to E.ON Business 

As we have noted that EON has two brands serving different types of business customers, we’ll highlight how each scores on Trustpilot. 

According to E.ON’s promotional materials they are on a mission to “provide decentralised, green and innovative” energy solutions. In 2019, E.ON was the first of the Big 6 energy companies in the UK to switch all of its electricity customers to energy generated from renewable sources.

In 2020, E.ON UK announced that it would be migrating customers over to a new subsidiary brand called E.ON Next, powered by rival Octopus Energy's Kraken system. E.ON Next has 2 million migrated customers from Npower and Powershop after E.ON acquired both companies.

Once E.ON bought the energy company nPower, and took over their customer base, they became the UK utility provider with the largest customer base.

E.ON business customers can choose from fixed gas and electricity plans as well as variable tariffs.

  • Is E.ON UK 100% Renewable?

    E.ON claim to offer 100% renewable energy. That means that all businesses contracted with the company access 100% renewable electricity, at no extra cost. However, the eligibility criteria are complicated and only apply to SME customers who sign a contract directly with E.ON. 

    100% renewable energy at E.ON is defined as electricity sourced from E.ON’s renewable generation assets, supply agreements with independent UK wind generators or energy bought with the purchase of renewable electricity certificates. The electricity supplied to businesses comes from the National Grid and DNOs.

    E.ON has invested over £3.3 billion in renewable energy generation, including wind farms and solar generation, in the last decade alone.

    Alongside their commitment to supporting the transition from fossil fuels to renewable energy, E.ON have come up with tailored support for business customers to help them reduce their dependence on fossil fuel technology. This includes advice and support in upgrading to solar panel and air pump energy generation and the installation of electric vehicle charging points. Customers can also use the E.ON See energy monitoring system to track their energy usage and reduce consumption.

  • Have E.ON Won Any Awards?

    E.ON has won numerous awards over the last decade. E.ON’s large-scale corporate energy efficiency projects saw them shortlisted for numerous recognitions and they were awarded the 2019 CIBSE Facilities Management prize.

    The company is proud of its diversity and inclusion mandate and has been recognised three times by Inclusive as an annual top 50 employers and awarded ‘Silver’ as part of the Armed Forces Covenant programme, which seeks to provide support for ex-servicemen and women to find work after the military careers.

    In 2020, the E.ON smart home app was awarded the Red Dot Design Award for ‘Interface & User Experience Design.

  • What Is E.ON UK's Cancellation Policy?

    It’s important to know that business E.ON energy customers face paying exit fees if they cancel an active contract before the renewal date. You may be charged an exit fee if you choose to change supplier before your renewal period, which with E.ON is 49 days before your tariff is due to end. Please refer to your tariff terms and conditions for more information.

    However, if you have been on an E.ON tariff for more than a year, it may still be worth switching even after factoring in the cost of exit fees. At Business Energy, we can advise you on what you stand to save and the fees applicable to an energy switch so you can decide if it is right for you - so compare business energy deals today, and save.
