E.On Next positions itself as a significant player in the UK energy market, offering a mix of fixed, variable, and innovative tracker tariffs. While not always the absolute cheapest, its “Next Pledge” tracker tariff offers a competitive option by staying below the Ofgem price cap.
The supplier scores highly on customer review platforms like Trustpilot, with a 4.5-star rating, and boasts a very well-rated mobile app with 4.8 stars on the App Store.
While its official customer service ratings from Citizens Advice are mid-table at 3.1 out of 5, its commitment to renewable electricity on certain tariffs and strong user-generated feedback make it a compelling choice for many.
Who are E.ON Next?
E.ON Next is the customer-facing brand for all residential and small business customers of E.ON UK. Launched to provide a more streamlined and digital-first service, it effectively replaced the traditional E.ON brand for new customers.
While it operates with a modern identity, it is fully backed by the scale, infrastructure, and resources of its parent company, E.ON, which is one of the UK’s most established energy firms.
What tariffs do E.ON Next offer?
E.ON Next’s tariff selection is designed to cater to a range of customer needs, from price stability to flexibility and green energy. Based on typical household usage, here are the key tariffs available:
Next Smart Saver v7: A time-of-use tariff for customers with smart meters, offering cheaper electricity at off-peak times, ideal for electric vehicle charging.
Next Pledge Tracker 12m v9: A variable tariff that tracks the Ofgem price cap but is priced to be cheaper over the year. It has no exit fees.
Next Fixed 12m & 24m: These tariffs lock in your energy rates for one or two years, providing protection against price rises. The 12-month tariff has a £50 exit fee per fuel, while the 24-month option has a £100 exit fee per fuel.
Next Gust 12m v33: A fixed-rate green tariff that guarantees 100% of the electricity is sourced from UK wind generators.
Next Flex: This is the standard variable tariff (SVT), where prices move in line with the Ofgem price cap. It has no fixed term and no exit fees.
How do E.ON Next compare on price?
E.ON Next’s pricing is competitive, but its value is highly dependent on the tariff you choose. The Next Pledge Tracker is one of the most competitive tracker tariffs on the market. Their fixed-rate deals offer security but may not always be the cheapest available.
Despite this, in the 2025 Which? energy survey, customers gave E.ON Next a low score of just two out of five stars for “Value for money,” suggesting many customers on standard or older fixed tariffs feel they are paying too much.
The table below shows the estimated costs for E.ON Next’s main tariffs based on typical UK household consumption.
| Tariff Name | Est. Monthly Cost | Est. Annual Cost | Contract Length | Price Type | Exit Fee (per fuel) |
|---|---|---|---|---|---|
| Next Pledge Tracker 12m | £143.30 | £1,719.67 | 12 months | Tracker | £0 |
| Next Fixed 12m | £144.10 | £1,729.31 | 12 months | Fixed | £50 |
| Next Gust 12m | £145.49 | £1,746.07 | 12 months | Fixed (Green) | £50 |
| Next Fixed 24m | £146.83 | £1,762.07 | 24 months | Fixed | £100 |
| Next Flex | £147.83 | £1,774.07 | No fixed term | Variable | £0 |
Costs are estimated based on Ofgem’s Typical Domestic Consumption Values (3,000 kWh electricity & 12,000 kWh gas annually) and are subject to change.

What do other E.ON Next reviews say?
Customer reviews for E.ON Next are highly polarised.
On Trustpilot, the company scores an ‘Excellent’ 4.5 out of 5 stars from over 162,000 reviews. This indicates that for many customers, particularly those with simple queries, the service is efficient and satisfactory.
| Rating | Percentage of reviews |
|---|---|
| Excellent | 74% |
| Great | 12% |
| Average | 3% |
| Poor | 2% |
| Bad | 9% |
However, the 2025 Which? energy survey provides a more critical view, placing E.ON Next in the lower half of the 17 suppliers rated with a customer score of 63%.
The survey, which polled thousands of energy customers, awarded the supplier a mediocre three-star rating for overall customer service but just two stars for value for money, with only four firms receiving worse customer ratings.
This suggests that while day-to-day interactions may be positive, the overall long-term customer experience and pricing satisfaction are below average.
How green is E.ON Next’s energy?

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