EON Energy 2019: Prices, Reviews & Contact

German-owned EON is one of the Big Six gas and electricity suppliers to households and businesses across the UK and abroad. They're the most significant investor-owned energy company in the world. Will they keep their top position given their high prices and poor customer service? Find out what they have to offer you and whether it's worth switching to them.


About EON Energy

EON soared to the top among the most popular energy suppliers in 2002 when it took over ‘Powergen', joining the ranks of the Big Six. But a lot has happened since then. Today, their popularity isn't what it once was. Let's take a look at EON's inception in Germany and how its growth in the UK market has evolved.

Discover at a glance what has become of EON over the past two decades since it launched into the UK energy market.


  • 2000 - EON was created in 2000 through the merger of two German energy companies - VEBA and VIAG.
  • 2002 - Operations started in the UK when EON acquired the previously government-owned Powergen.
  • 2003 - EON entered the gas market through the acquisition of Ruhrgas (later: EON Ruhrgas), which boasted a strong presence in more than 20 European countries.
  • 2005 - EON acquired Swedish power company Sydkraft AB, which then changed its corporate name to EON 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 - EON 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 - EON acquired renewable energy utility company, Innogy, through a complicated €43 billion asset swap deal between EON, Innogy and RWE (Innogy's controlling shareholder). EON announced in the same year that it would axe 500 jobs in the UK.
  • 2019 - EON was the first energy supplier to state that it will hike up its prices once Ofgem raises the price cap on standard and default tariffs on 1st April 2019.


Customers: EON supplies energy to over 4.3 million residential and business customers in the UK, where it holds about 13% of the market share.

Staff: EON employs around 9,400 people across the UK and approximately 43,000 people worldwide.

Management: EON UK's Chief Executive Officer (CEO) is Michael Lewis. Chris Lovatt manages the residential customer sector, while Michael French leads the business customer arm.

Operations: EON segments its services into three operating units: Energy Networks, Customer Solutions, and Renewables. It reports its nonstrategic activities under Non-Core Business. Let's have a quick look at each group:

  1. Energy Networks - EON subdivides the segment relating to its power and gas distribution network into three regional markets. These are Sweden, Germany and East-Central Europe (which consists of Romania, the Czech Republic, Hungary, Slovakia, and Turkey).
  2. Customer Solutions - This segment serves to supply customers in Europe (excluding Turkey) with gas and electricity. EON's leading presence is in Germany, the UK, Italy, Sweden, Hungary, Romania and the Czech Republic. EON's turn-key distributed-energy solutions are also part of this segment.
  3. Renewables - The renewables segment consists of Onshore Wind/Solar and Offshore Wind.
  4. Non-Core Business - EON's non-strategic activities include the operation of its nuclear power stations in Germany and the generation business in Turkey.

EON's energy portfolio

EON places a key focus on renewable electricity. You'll see these two words plastered across its marketing material since July 2019. This is when it announced that it would provide all of its 3.3 million domestic customers with 100% renewable electricity. So where does it get its renewable energy? In large part, from its portfolio of renewable energy sources, from wind farms to combined heat and power units. Let's take a look at them here:


 Offshore wind farms are located out at sea or in freshwater. EON operates four of these in UK waters. It has also teamed up with London Array to create the world's largest operational offshore wind farm. Onshore wind farms are located on land. EON has developed 15 functional UK sites since 1991.

 Biomass is usually organic waste that can be broken down to produce green gas. EON operates the Blackburn Meadows site which powers more than 40,000 local homes.

 Combined Heat and Power (CHP) units generate on-site electricity, capturing the heat produced from the process. It can be used elsewhere in your building for heating, hot water or air conditioning. A CHP unit is reported to reduce a household's energy costs by up to 20%.

EON's community work

EON has a dedicated Community Relations team that raises funds for its charity partner, Alzheimer's Society. EON's fund-raising activities have ranged from baking goodies to climbing mountains and bungee jumping. It has raised £27,000 to date for the research charity.

Shares and finance

EON's shareholder structure is composed of roughly 80 per cent institutional investors and 20 per cent retail investors. Investors in Germany hold about 31% of EON's stock, while those outside Germany account for approximately 69%.

EON in the news

EON is not shy of the limelight given to it in the press. Let's look at what has been making the headlines:

EON issues EUR 1.5bn of green bonds (Aug 22, 2019) - German utility EON SE raised EUR 1.5 billion through the issuance of green bonds. EON said it would invest the proceeds to finance renewable energy grid connections, charging stations for electric vehicles (EVs) and the roll-out of smart meters.

EON preps for squeeze-out at Innogy (Sep 6, 2019) - German utility EON SE bought a 76.8% stake held by rival RWE AG in Innogy. This was part of a complicated asset swap between the energy groups. The plan includes merging Innogy into EON Verwaltungs SE in return for cash compensation. EON is waiting for the go-ahead by the European Commission.

EON’s merger with Npower leads to 900 job losses (Dec 28 2018) - Npower announced that it would axe 900 jobs, that-s 14% of its workforce. The reason given by CEO Paul Coffey, was to lower operating costs and make the merger more palatable. Coffey anticipates increasing EON’s 13% market share significantly post-merger.

EON to cut 500 UK jobs as it prepares for energy price cap (1 August 2018) - EON announced its plans to axe approximately 500 jobs across the UK, namely from non-customer facing departments. It blames the price cap for the need to reduce costs. It plans to make the redundancies voluntary where possible. According to CEO Michael Lewis, the redundancies are expected to save around £100m across EON's mid-term plan.

EON to reimburse customers £12 million for mis-selling (16 May 2014) - Ofgem ordered EON to pay out £12 million to 330,000 customers due to mis-selling energy plans between June 2010 and December 2013. Each customer would receive around 35 pounds in compensation. EON acknowledged its failings and agreed to cease using third party agencies for doorstep selling and cold-calling.

Fuel mix

There seems to be confusion around EON's percentage of renewable energy in the fuel mix of its electricity supply. In July 2019 the supplier announced that it would provide all of its 3.3 million residential customers with 100% renewable electricity at no extra cost. It goes on to specify in its website that "every unit of electricity you use is backed by 100% renewable electricity from our renewable assets".

But when we looked closer at its fuel mix published on its website, we found that renewable energy only accounts for a meagre 16.7% of its electricity supply. It turns out that its claim of using "100% renewable sources" actually means that it "can potentially" deliver 100% renewable energy if it wanted to, but it doesn't! Let's take a closer look at what its fuel mix actually looks like:

Activities and services

EON seems to be riding the eco-friendly bandwagon to appear as green as possible. This is coupled with its drive to make customers’ homes more energy efficient. Customers can see this reflected in the array of EON's services, ranging from charging stations for electric vehicles to the latest model of smart meter.

EON Drive

EON Drive is EON's network of electric vehicle chargers across the UK, designed to be installed in the workplace and at home. It has also teamed up with the EG Group to roll out ten Ultra-Fast Charging (UFC) stations over the next two years in the UK.

Such a new high-tech service would rarely go without a smartphone app, so EON has provided one. With the aptly-named EON Drive app, users can log in to see connector types and tariffs for each charge point in Europe and make payment directly from their smartphone.

Are you having trouble logging into your EON account online? Find the solution in our EON Login guide.

The EON Drive app is available to download for Android and IOS.

Boiler Cover

EON offers boiler cover to its customers through its affiliated insurer HomeServe. By going through EON, customers can benefit from special rates for boiler cover.

The perks of boiler cover with HomeServe include a free boiler service (usually £84*) in the first year. If your boiler can’t be repaired, their gas-safe registered engineer will replace it. You also get a 12-month guarantee on most boiler repairs and an appointment window that suits you.

However, HomeServe doesn’t offer bespoke boiler cover for landlords, as does 24/7 Home Rescue Plan, as reviewed in our Best Boiler Cover guide.


EON knows that its customers will readily switch supplier if they don't feel valued for their loyalty. That's why it offers its customers rewards, firstly just for joining, and additionally, if they install solar panels at home and generate electricity.

Customer rewards

EON Rewards scheme allows you to start collecting points as soon as you've signed up. You don't need to do anything to get your points - they accrue automatically on your account.

You can spend your Tesco Clubcard points whenever you like. If you collect Bonusbond vouchers in £5 amounts, simply login to your account to redeem them as you receive 500 points. Sign up to the EON Rewards scheme for free online or over the phone.

Solar Rewards


FiT has been phased out for new solar panel owners. The UK Government has stepped in with a replacement scheme, the SEG (Smart Export Guarantee) that operates along the same idea, allowing individuals to sell energy back to the grid. Solar Rewards is the name given by EON under SEG. Through the Solar Rewards, EON customers will be paid 5.24p per every kilowatt-hour (kWh) of electricity they export to the grid.

Smart meters



You'll know from our Smart Meter guide that this nifty little device can put you in control of your energy consumption. It shows you how much you’re spending day to day, compares periods of expenditure, and predicts future bills to help you budget. If you're an EON customer who pays by direct debit, you can get it installed for free.


The UK government wants everyone in the country to have a smart meter installed before 2020. To sign up for one, log into your online account and head to the page entitled "smart-meter-booking-tool".

Schemes to help reduce your bills

With stiff competition from its Big Six cousins, EON is eager to retain its customers wherever possible, even those struggling to pay their bills. That's why it promotes several schemes which help clients recover their financial stability and resume their payments. Let's take a look at what these schemes are and how they could benefit you if you're a struggling EON customer.

Warm Home Discount

The Warm Home Discount is a government-led programme that takes £140 off recipients' energy bills during the colder winter months. The scheme is available for pensioners and other specific individuals at risk of fuel poverty.

EON is a participant in the programme. You can apply for it online on EON's website. Just look for the page entitled "warm-home-discount-form". Get the EON Warm Home Discount now.

EON Energy Fund

The EON Energy Fund is designed to help its customers reduce or clear their arrears on unpaid gas and electricity bills. If you meet EON's criteria, the Energy Fund could help you…

  • Pay off your current or final EON bills.
  • Replace appliances.
  • Repair gas boilers.

Find out if you're eligible for the Fund and what you need to get it by heading to our EON Energy Fund guide.

Affordable Warmth


Affordable Warmth is the name given to the home efficiency programme following the government's implementation of the Energy Companies Obligation (ECO). ECO requires energy suppliers to help their customers improve their homes' energy efficiency. You don't need to be an EON customer to get it.

It's part of the government's goal to reduce greenhouse gas emissions in line with its 2050 Net-Zero pledge. It also aims to pull UK homeowners out of fuel poverty and keep their homes warm all year round while reducing their heating bills. Apply for the grant online.

Feed-in tariff

The Feed-in Tariff (FiT) was a government-run scheme that launched in April 2010, designed to encourage households to install energy-generating devices, such as solar panels and wind turbines.

While domestic customers can’t apply for FiT any longer, businesses can still apply for FiT up to 31st March 2020. For the application to be valid, the installation must have been certified by the Microgeneration Certification Scheme (MCS) and commissioned on or before the cut-off date.

For any questions on EON's FiT scheme, find the relevant contact details in our EON Contact guide (coming soon).

EON tariffs and prices

We can subdivide EON's tariffs into fixed and variable, with variances for Economy 7 rates and those for business customers. Let's take a look at each type offered by EON:

Fixed Tariffs

A fixed tariff is one where the price you pay for the unit rate will not change during the term of your contract. It will protect you from any price increases in the wholesale energy market. Let's take a look at EON's fixed tariffs and their corresponding contract lengths:

  1. Fix Online v31 - Term: 12 months
  2. Fix 2 Year v4 - Term: 24 months
  3. Fix and Drive v7 - Term: 24 months (for electric and hybrid vehicle owners)
  4. Fix and Boiler Cover v24 - Term: 12 months (with the option of boiler cover)

Variable tariffs

A variable tariff is a plan in which you must pay a defined unit rate for each unit of energy you use. However, this prescribed rate will move up or down to reflect changes in the wholesale market and other costs faced by EON. If EON decides to increase your unit rate at any point, it should give you at least 30 days' notice before any changes take effect.

In addition to the flexibility of paying only the market rate for gas and electricity, you can switch to an alternative tariff or supplier at any time. That's because there's no contract end date. There won't be any exit fees to pay either. EON's two variable tariffs are as follows:

  1. EON EnergyPlan - Available with direct debit discount.
  2. EON EnergyPlan Assist - Available if you've received the Warm Home Discount.

Economy 7 tariff

While not considered a separate tariff, Economy 7 can be any one of EON's set fixed tariffs, but with two different rates. You get a nighttime rate (i.e. seven hours of low prices during the night), and a daytime rate, which is more expensive than EON's standard tariff, the "EON EnergyPlan".

Will it help me save money? Check out our Economy 7 guide to find out if you could benefit from this tariff.

If you're interested in getting an E7 meter and you want the corresponding E7 tariff from EON, contact them directly. Find their Economy 7 contact number in our EON Contact guide.

Prepayment tariffs

If you have a prepayment (or PAYG) meter installed in your house instead of a standard credit meter, you'll be paying for your energy in advance. EON offers two pay as you go (PAYG) tariffs:

  1. EnergyPlan with Smart Pay As You Go
  2. EON EnergyPlan with Prepayment

Get the details of each of these, including the relevant Tariff Information Labels in our EON Tariffs guide (coming soon).

Business tariffs

EON boasts more than 10,000 business customers according to its website. But remember that there are lots of other factors to take into account when looking for the best business energy supplier. For one, you must ensure that your supplier caters to your industry and business size.

Then you need to decide what kind of energy contract is best for you: rollover, fixed, etc. Once you've got these things sorted, switching business supplier is easy. Let's take a look at the process and the types of energy plan or contract available to your business.

How to switch business energy supplier

The method you'll go through to get your business premises supplied by EON is as follows:

  1. Get an energy quote by heading to the business section of EON's website. You'll need the following information:
  • The address of your business premises or your MPAN number.
  • How much energy you use, either in kWh or in pounds (per year/6 months/quarter/month)
  1. Pick a plan* to suit your business and confirm your switch.
  2. EON will contact your previous supplier to process the switch. You will then be sent a welcome pack with details of your new business tariff.
  3. EON will ask you for a meter reading to ensure that your first bill is accurate. It takes around six weeks to change to EON.

*Should you pick a fixed plan or a bespoke contract?

Whether you should get a fixed plan or a bespoke contract depends on how much your business consumes in energy per year:

  • If you spend less than £175,000 or use less than 1GWh of gas or electricity a year, you should pick one of EON's fixed business energy plans.
  • If you spend more than £175,000 or use more than 1GWh of gas or electricity a year, you should choose a bespoke energy contract*.

*An energy contract is a bespoke energy plan offered by EON to protect your business from any fluctuations in market prices. In turn, this helps to reduce your company's risk and to budget more efficiently for future energy bills. There are three types of energy contract available for your business:

  1. Fixed Energy Contract: You'll agree with EON on the duration of your contract throughout which your unit rate will remain the same. Your business will be protected from rising wholesale energy costs.
  2. Multi-Purchase Contract: You'll decide when to fix your energy price over a fixed period. EON's experts will seize upon favourable market conditions to bring your energy costs down.
  3. Flexible Energy Contract: You'll get to fix and unfix your contract duration for up to five years. You'll manage your contract prices and take advantage of beneficial market conditions.

If you want to contact EON about getting your business supplied by them, find their contact details in our EON Contact guide.

Business solutions

EON also offers its customers tailored solutions to enhance your business' energy savings. These include the following:

  • Optimisation and storage
  • Battery storage
  • Electric vehicle charging
  • Energy consultancy
  • Demand-side response

How do EON Energy Prices compare to the market average?

When we refer to the market average, we've taken Ofgem's price cap as a benchmark to compare tariff prices among energy suppliers. That's because most suppliers charge up to the maximum price cap, currently set at £1,254 per annum for average household energy consumption on a dual fuel tariff.


EON's prices on its standard tariff are on average £1,261.64 per year, based on a three-bedroom flat in London on EON's variable EnergyPlan with an average consumption for three occupants.

EON's standard tariff is £7.64 more expensive than the price cap. Although this is under a tenner, it could be a lot less with a cheaper supplier, such as Tonik Energy.

In summary, EON's prices are high and not competitive. That's why EON receives a measly 1/5 stars from us for its prices.

Customer reviews and Selectra's verdict

Let's see how customers have reviewed the services and products received from EON before we come to Selectra's verdict on this supplier.

Customer reviews of EON

Their customer feedback on independent review sites is poor. Their worst review average by far is on Trustpilot, with a dismal overall score of 2/5 stars. A full 82% of the 2,476 reviews published rated them as "bad" - the lowest rating. Ouch!

You'll see in our EON Reviews guide (coming soon) what the complaints tend to relate to, and what EON is doing about it. Since the supplier claims to be transparent in reporting grievances, you'll be in for a good read!

EON also features towards the bottom when responding to live chat queries. Out of all energy suppliers in the UK, only British Gas and Bulb Energy took longer to respond on average.

They fare slightly better on Which?, receiving an overall customer score of 57%. They consistently received three stars across all the survey's categories used to calculate the overall rating: bill accuracy, phone customer service, etc. Nevertheless, compared to its competitors, EON ranked 23rd out of 30 energy suppliers, meaning there's still plenty of room for improvement!

Selectra's verdict

Selectra's verdict was arrived at by taking many factors into account. These included EON's pricing compared to the market average, customer review scores, fuel mix and extra customer perks. Overall, we give EON Energy a rating of 2/5 stars. Here's our summary of what the supplier has going for it:

 The Pros  The Cons
Extension of FiT scheme through Solar Rewards programme. High prices and inaccurate billing.
Range of plans and energy contracts for business customers. Poorly reviewed customer service.
Roll-out of SMETS 2 smart meters. Low % of renewables in its fuel mix.

Ovo Energy: Selectra's verdict - ★★
