About E.ON

E.ON UK is one of the biggest energy suppliers in the UK. Originally starting out as Powergen, it later became E.ON Energy during 2001. E.ON currently supplies around 3.8 million customers and offers a range of products including prepayment tariffs and boiler cover.

Let's take a look at the supplier's inception in Germany and how its growth in the UK market has evolved.

  • E.ON Timeline
  • 2000 - E.ON was created in 2000 through the merger of two German energy companies - VEBA and VIAG.
  • 2002 - Operations started in the UK when E.ON acquired the previously government-owned Powergen.
  • 2003 - E.ON entered the gas market through the acquisition of Ruhrgas (later: E.ON Ruhrgas), which boasted a strong presence in more than 20 European countries.
  • 2005 - E.ON acquired Swedish power company Sydkraft AB, which then changed its corporate name to E.ON Sverige.
  • 2014 - UK energy sector regulator Ofgem ordered the supplier to pay 330,000 customers £12 million due to poor sales practices between 2010 and 2013. It was the most substantial penalty ever imposed on a UK energy supplier.
  • 2016 - The supplier announced that it would abstain from fossil energy in the future. It transferred its fossil energy businesses to a new company, Uniper. This arm was sold off in 2017.
  • 2018 - E.ON acquired renewable energy utility company, Innogy, through a complicated €43 billion asset swap deal between E.ON, Innogy and RWE (Innogy's controlling shareholder). E.ON announced in the same year that it would axe 500 jobs in the UK.
  • 2019 - The supplier absorbed Npower’s domestic retail division and announced the creation of E.ON Next.
  • 2020 - E.ON makes plans to merge Npower Business Solutions with its own Industrial & Commercial supply units by the end of 2021.

Who Owns E.ON?

E.ON UK is owned by German company E.ON SE. Prior to its 2002 acquisition, the company was known as Powergen.

E.ON Energy and Npower

E.ON acquired the domestic retail division of Npower in 2019. In April 2020, Npower said it would also combine its business retail operations. E.ON also announced the creation of E.ON Next along with the acquisition.

The acquisition made E.ON the second largest domestic supplier in the UK, just behind British Gas and in front of Ovo Energy.

E.ON Tariffs


E.ON offers a number of different plans for all meter types and payment methods. Prices depend on your location and the amount of energy that your household consumes. As with most UK energy suppliers, E.ON’s prepayment meter tariffs tend to be more expensive than plans for customers who have credit meters.

E.ON tariffs are no longer available due to the transfer over to E.ON Next. The list below are those tariffs that existing customers might still be on and were offered in the past.

E.ON Fixed Tariff

The cheapest E.ON fixed tariff that was available was the Next 2 Year v12. This tariff did not have exit fees and fixed your unit rates and standing charges for 24 month.

E.ON Variable Tariff

The main E.ON variable tariff that was on offer was called the E.ON EnergyPlan. Like all standard variable tariffs, the E.ON EnergyPlan didn’t have fixed rates and prices would fluctuate from month to month. For customers on the E.ON EnergyPlan, the current rates are:

E.ON EnergyPlan Tariff (Direct Debit Payment Method)
Cost type Price
Electricity unit rate 29.484p per kWh
Gas unit rate 7.319p per kWh
Electricity standing charge 41.660p per day
Gas standing charge 27.219p per day
Total estimated cost per month £176.27
Total estimated cost per year £2,115.23
Exit fee £0

*Calculations based on a three-bedroom London household with average energy consumption. Tariff last updated: March 2022

There was also the E.ON EnergyPlan Assist which was exclusively offered to customers with a credit meter and eligible for the Warm Home Discount.

E.ON Prepayment Tariff

For customers who have a traditional prepayment meter, there was one tariff on offer called the E.ON EnergyPlan with Prepayment. This was a variable tariff that did not include exit fees and needed an electricity key or gas card to top up. These are the current rates for the E.ON EnergyPlan with Prepayment:

E.ON Standard Tariff (Prepayment Payment Method)
Cost type Price
Electricity unit rate 29.243p per kWh
Gas unit rate 7.308p per kWh
Electricity standing charge 46.610p per day
Gas standing charge 37.275p per day
Total estimated cost per month £169.27
Total estimated cost per year £2,031.19
Exit fee £0

E.ON Reviews


E.ON has been scoring consistently poorly according to most review websites. Due to the transfer over to E.ON Next and the confusion that has generated, many customers have felt left in a lurch. As well as the migration, E.ON customers have objected to the price hikes following the April Price Cap Rise.

E.ON Trustpilot

E.ON UK has an overall ranking of 3.4 of out 5 stars on customer review site Trustpilot. It appears that customers have had quite mixed experiences with the supplier – while 59% of customers have rated E.ON as either ‘Excellent’ or ‘Good’, 35% of the customers who left reviews on Trustpilot gave the supplier a ‘Poor’ or ‘Bad’ rating.

E.ON UK Citizens Advice

In Citizens Advice’s most recent quarterly ranking of UK energy suppliers, E.ON came near the bottom of the pack at 19th place out of 21 providers. The supplier fared well when it came to bill accuracy. However, E.ON only received 1.8 out of five stars when it came to dealing with complaints and ease of contact.

E.ON UK Which?

E.ON UK came joint 11th place out of 18 on Which?’s survey of energy providers. E.ON received an overall score of 55%, scoring poorly for bill accuracy and value for money.

E.ON Customer Service

Overall, the E.ON customer service experience has deteriorated significantly. This has mostly been due to the migration of customers over to E.ON Next. E.ON have been receiving a higher volume of calls than they usually would do and this has impacted their customer service.

However, E.ON Next has been performing much better and whatever your experience with E.ON, you’re bound for a better service with E.ON Next.

E.ON Prepayment


Customers that have a standard prepayment meter must top up their E.ON electric key or gas card at a local PayPoint, Payzone or local Post Office.

If you run out of credit and are not able to top up, your meter will automatically provide you with at least £5 emergency credit. This amount will be deducted from your balance the next time you are able to top up.

E.ON Top Up

If you have a smart meter, you can either top up your meter online, over the phone or via the E.ON app. The E.ON app is free to download. In addition to allowing you to top up your meter in just a few seconds, it will also store all of your payment history and top-up codes.

For E.ON customers with smart meters, your meter will not disconnect from 4 pm to 11 am Monday through Friday, nor on Sundays or Bank Holidays. As with emergency credit, you’ll need to pay for the energy you consumed during those times the next time you top up.

E.ON Warm Home Discount


E.ON customers may be able to take advantage of the Warm Home Discount. This government scheme is designed to help households that are at risk of fuel poverty during the winter months, which tend to be more fuel-intensive.

The Warm Home Discount takes the form of a one-off credit of £140 on your electricity bills from October to March. Find out if you qualify with our E.ON Warm Home Discount guide.

If you’re not eligible for the Warm Home Discount, there are still lots of other ways to get support, such as with the E.ON Energy Fund. Check out our guide to government grants and schemes to see what extra help you can get with your energy bills.

E.ON Smart Meter


E.ON has already installed over 2 million smart meters across the UK. The supplier began rolling out the second generation of smart meters (SMETS2) in 2018. These meters are compatible among suppliers, meaning that your meter won’t lose its smart functionality if you switch to a different energy supplier.

Head to our E.ON smart meter guide for more information.
