E.ON Next

E.ON Next is E.ON’s response to the challenge from new energy suppliers who have been using technology and innovation to drive prices down while also supplying more environmentally friendly energy.

  • Backed by E.on, one of the Big Six energy companies
  • Environmentally friendly energy
  • Not currently accepting new pre-payment customers
  • Electric vehicle tariff only available to Tesla owners
  • No live chat option on website and relatively short call centre opening times

Who are E.ON Next?

E.ON are one of the “Big Six” energy suppliers and in recent years, this Big Six has been coming under pressure from new energy suppliers who have been using technology and innovation to drive prices down while also supplying more environmentally-friendly energy.

E.ON Next is E.ON’s response to this challenge.

What tariffs do E.ON Next offer?

The tariffs available change regularly but currently there is one variable-rate tariff as well as a fixed-rate tariff covering one and two years.

The variable tariff is a ‘no frills’ tariff but it does include a discount if you pay by direct debit.

Both of the fixed tariffs include 100% renewable electricity along with a discount for paying by direct debit. For both of these, you do have to have a smart meter installed if you don’t have one already.

The 1 year fixed tariff has exit fees of £75 per fuel, whereas the 2 year fixed tariff has exit fees of £150 per fuel.

How do E.ON Next compare on price?

E.ON Next are not the cheapest energy provider although their prices are competitive. For example, their charges for their variable tariff (in the East Midlands) are below:

FuelStanding ChargeUnit Charge
Electricity50.31p per day26.76p per kWh
Gas29.11p per day6.76p per kWh

You can see how they compare with other suppliers in price in our guide on the cheapest gas & gas and electricity prices.

Data from Trustpilot. Correct as of 10/11/2023

In their annual report on the country’s best suppliers, Which? rated E.ON Next as 15th out of the 21 suppliers that they rated. This was based on a survey of over 10,000 energy customers across the country along with a separate assessment from Which?.

How green is E.ON Next’s energy?

E.ON Next’s electricity comes from 100% renewable sources.

They also generate their own renewable via biomass plants located in Lockerbie and Sheffield. These biomass plants generate enough electricity to power 100,000 homes.

The gas provided to customers on the E.ON Next Climate+ tariff is green thanks to carbon offsetting.

In addition, E.ON Next will plant five trees per year in the Peruvian rainforest on behalf of customers on this tariff, and they claim these trees are capable of removing 100kg of CO2 from the air.

What is E.ON Next’s customer service like?

Citizens Advice provides an independent, quarterly review of every supplier when it comes to customer service. E.ON Next came 10th overall, out of 20 different suppliers.

CriteriaRating (out of 5)

The same survey found that if you wanted to contact E.ON Next by phone, then the average call centre waiting time was 2 minutes and 15 seconds.

They also found that E.ON Next responded to 75.9% of emails within 2 days. 96.2% of customers received an accurate bill at least once a year and 97.7% of switches were completed within 15 working days.

When it comes to complaints, E.ON Next received 1,712 per 100,000 customers with 70.8% of these resolved in less than a day and 91.8% of complaints resolved within 8 weeks.

What is E.ON Next’s website/app like?

E.ON Next’s website looks clean and it is easy to find the information you need.

The online portal enables you to do everything you need to do, including managing your account, viewing your tariff and previous bills and submitting meter readings.

There is no live chat feature, although E.ON Next claim to be contactable via email or social media between 8 am and 10 pm, 7 days a week. These are longer opening hours than their phone-based call centre.

They have an app in both the App Store and Google Play Store. This app appears to be very good, with a rating of 4.8 from over 21,000 customer reviews. The app allows you to send meter readings, view statements, make payments, check your tariff details and manage your account information. It also works for Pay As You Go customers.

What billing options are available?

E.ON Next prefer customers to pay via monthly direct debit and customers get a discount for paying this way. Quarterly payments are not possible.

The monthly amount is based on the estimated annual cost divided by twelve, so during the summer months, it is likely that a customer will be in credit as they will be using less energy, although in the winter months that credit will be used up as they will be using more energy than they are paying for.

A customer who believes that their monthly direct debit amount is wrong can contact E.ON Next to have the amount reviewed.

As well as direct debit, customers can also pay by credit or debit card either online or by phone, by bank transfer or cheque, or by cash at a Post Office, PayPoint or Payzone.

There are no discounts for paperless billing, and E.ON Next are not prepared to accept new customers on pre-payment accounts.

Do E.ON Next offer smart meters?

E.ON have already installed two million smart meters in the UK. Provided a smart meter is suitable for your property, they are happy to install one for free.

Some of E.ON Next’s tariffs are only available to people who have smart meters or agree to have a smart meter installed.

Do E.ON Next offer a recommend a friend referral scheme?

Yes, E.ON Next do offer a recommend-a-friend scheme. If you are a customer, both you and anyone you refer will receive £50. There is more information here.

Hi, I'm Rob and I run I initially started this project 5 years ago when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data backed reviews on all the suppliers available. Since then, I spent have a lot of time (too much some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible and any data is backed up by a source where necessary. I have also started writing guides on various energy related topics which hopefully you will find useful. If you find any issues, please use our contact form to let us know.

  1. EON.Next are currently not following up on their promises to refund in credit the customer. On three separate occasions, each call with different staff were voice recorded to prove the shortfall. The main point of the calls being that the utilities provider did promise on each subsequent timeline to refund soonest my bank account. So far, no funds show. On my last recorded call, I had several apologies and a £10 goodwill credit placed against my utilities account. However, no merit whatsoever as I need the funds returned to my bank account asap. This would amount to transparent criminal bureaucracy. Would the EON.Next CEO like to comment? Perhaps.

  2. How can E.ON charge so much for duel fuel? They are a rip of company and are exploiting us and are allowed to be Boris Johnson’s GVT.
    How can E.on increase bills by so much? Just under a year ago (March 21) my estimated annual dual fuel cost through E.ON was £574 – I live alone and so am a low user. But the cost have gone up more than 100% in less than 12 months. I just don’t understand it. I know bills have increased but not by this much surely. Now I use even less than I did 12 months ago due to fuel increases and my estimated cost for the next 12 months is £1335! That is about 120% increase and that is without the expected 58% increase in April. Why is there nothing the UK GVT is doing to help people like me? Living on a state pension I can’t cope, it’s crazY!! I am sure it cannot be that bad with other companies!!

  3. I am transferred from Eon to this new company and no one tells me if it is ok for me I have to close my account because I have to move and they say I will be refunded £103 in the next 6 weeks after 7 weeks I have to ask what happened I don’t I still get my money back, and I get the reply: it was a billing error and that I only get £68 back and it may take 10-15 days for the money to reach my bank.
    I answer that I am not very happy with this situation and especially with the money and time lost, but these companies can do with you what they want to do because, as a customer, you are always wrong.
    Terrible experience with this company. I really don’t recommend it. If you like to be treated very badly and as an idiot this is the company, you can do business but keep in mind that this situation is not really good.

  4. besides tariffs (day/night per kwh), being dear and so are the standard charges but howevew aligned to other suppliers, the website ‘called’ dashboard page showed an incredible high amount in debt which is incorrect (£ 1550 approx !!!!!) I emailed them. I take almost weekly readings which I put online there must be an imput error from their end.

    I previously emailed because I noted that the readings dates I input online do not correspond on their website and they admitted that on their reply.

    I am with eo-next and i have been utterly disgusted with the level of service I sent them a meter reading on the 17th sept expecting to get my bill in 10 to 14 days but up to now i have had no bill.I have tried several time to get in touch with their customer service by phone at different times of the day just left for hours nobody bothers to answer the dam phone talk about disgusting customer service the treat us very badly.Have sent an e-mail i await with bated breath to see what excuses they come up with. I would rate them one on every aspect, how anybody can give them a higher rating i don’t i am disgusted with the poior level of srevice i am getting may be a enquiry to the ombudsman can help

  6. Very expensive,,on a pre payment meter. Disgusting, we had no choice in being switched from Npower

  7. We were also transferred to Eon Next from nPower this year, I was half expecting to have to switch away but while it’s early days we have found it a positive experience so far.

    Eon Next may not be the very cheapest but their fixed tariffs are quite competitive and their customer service, which is very important to me, has been good. Their staff reply to emails very quickly and helpfully and their website is clear and easy to use so you dont really need to phone and switching tariffs and fixing costs for a year was easy.

  8. I have already cleared my balance with eon energy but somehow this eon next keeps on sending me a letter threatening me to send Debt collector.

    I have already contacted eon energy and they assured that there is nothing to pay. I contacted eon next couple of weeks ago and provided them with the detail of the bank transaction but in their account, I can still see the amount in debt.

    It is incredibly frustrating and no one either at eon energy or eon next is dealing with this matter.

  9. We were switched from Npower to E.on Next a while ago,and so far it’s been a very positive experience!
    The E.on Next app and website is excellent,far superior to that of Npower!

    There has been very good communication via email.Early notifications of the imminent ending of our existing fixed rate deal was received, and a good choice of new tariffs was offered, including fixed rates.☺

    We were easily and instantly able to change to our preferred tariff on line with no difficulty,and confirmation immediately received.

    All in all we are perfectly happy with E.on Next ??
