E.ON UK Reviews 

After complaining about my direct debit they came with a solution to put me on to a variable direct debit. Great service and they resolved my complaint

Corrupt rotten company whose sole aim is to Skank as much money from public as possible

The lady l spoke to on Tuesday about the complaints phoned me today to confirm everything has been corrected
I am extremely pleased with being so quick in resolving all

i booked in a meter check as the cost of the bills was excessive.Twice on separate days no one turned up,they hadn't booked in a engineer at all.
Money taken out of my account that didn't match the invoice balance.
we had a next appointment booked for Monday 22/6 for the meter to be checked, they have just informed me that it has been cancelled due to me going to another supplier.
shoddy service.

Called today and made to speak to AI system first before reaching actual person who can understand you. And when finally connected to energy advisor (human) she said hello asked for my full name and then dropped the phone call after I told her my full name. Disgrace of a company!

Mark (M60282).engineer was a very communicative, helpful and as done great job. Making me understand how to use energy efficiently, generally he was a good man. Very neat and tidy work, I would have him back to my property work. I have given him 5 stars and would have loved to give more if I could

I am extremely disappointed with the service I have received.
I first noticed unusually high charges in September 2025. I promptly submitted meter readings, expecting my bill to be corrected. Instead, the charges increased.
In May, I again submitted updated readings and raised my concerns, asking for clarification, but received no response. I then escalated the matter to the complaints department.
Throughout the complaints process, I received several contradictory responses:

I was told my account had been billed using estimated readings for nearly a year
Then I was informed that my submitted readings had been updated and my account was in credit
Later, I was advised that there were no issues and everything had been checked and confirmed as correct
Finally, I was told the account was accurate but simply required ongoing meter readings

Despite all of this, after a prolonged discussion and multiple submissions of accurate readings, I was charged the same amount again in June (£148.82), with no visible correction applied.
This raises serious concerns about the accuracy of billing and the handling of customer complaints. Based on my experience, I have little confidence that customer concerns are properly reviewed or resolved.

We've just moved house, the house we moved into had recently been signed off with an electric safety certificate but a week after living there the power went off. EON came out with in hours, a really nice thorough engineer called Mark (M60282) did an amazing job in finding the issues and pretty much rewiring the whole fuseboard! Very thorough, very knowledgeable and very polite. Rare to see someone who takes so much pride in their work. Couldn't be happier.

I switched both my gas and electricity supplies to E.ON over two months ago, but only the electricity transfer was completed. Despite numerous phone calls and emails, E.ON has still failed to resolve the issue with my gas supply.

British Gas has confirmed there is no reason preventing the transfer, yet E.ON has repeatedly promised callbacks that never happen. Communication has been extremely poor, and I am constantly having to chase for updates.

As a result, my account is not on the correct tariff, and I have no clarity on what I am expected to pay. After more than two months, I am still waiting for a resolution.

This has been a very frustrating experience. I would expect a major energy supplier to handle account transfers more efficiently and keep customers properly informed. Unfortunately, my experience has been the opposite.

i feel like they change the rules according to what suits them, if it wasn't for the fact i feel every energy provider in the UK is the same i would change... what's the saying Same S...T different bucket.. Absolute Tripe. and please EON don't offer to look at my case because it wont get resolved because it doesn't suit you so please don't bother I'm not interested. 👍

We had Dan the engineer from EON arrive this morning to fit and sort out for my gas and electric smart meters. He did a great job, very professional, helpful and knowledgeable. An absolute credit to EON and I would highly recommend to anyone thinking of having smart meters fitted to contact them and get it done.

They are the scum of the earth, i told them i do NOT want to contract with them (after the disgusting way they were before) and they still think they can bill me for serviced i never asked for or wanted

then sent LCS to harass me relentlessly to attempt to get me to pay their imaginary bill

DO NOT CONTRACT WITH THIS SCUM!!!!!!!!!!!

Please avoid Eon unless you have plenty of time on your hands to be messaging and phoning them and then for nothing to be done.
If you have a question the staff just ask Google or AI and pass it on to you and it’s often incorrect.
Eon cannot seem to read my smart meter, or can they? They cannot make up their mind if it’s working or not ! So now I await an engineer visit week commencing 13th July in the morning. When I pointed out that week commencing is not an actual day but an entire week they assured me that an engineer will arrive on the 13th between 8 and 12, I am not holding my breath!!!
Eon have managed to put my bill right because they first mixed up the night and day readings. I am getting several bills a month and I would like just one monthly bill. Why send bills for just 6 or 14 days several times a month?

Why, after 3 months is the app only able to show a few hours usage in March?

When I was with Fuse the bills were correct and I could see my usage as I used it. What the point of a smart meter if you cannot see your usage for 3 or 4 months after you have used it?

If you switch to Eon be prepared for them to waste many many hours of your time.

All they care about is increasing prices without a reason, and when you do question why, they never have a reasonable answer. They promised to keep my direct debit at a certain price but they lied and took much more than they said. I would avoid them as there are so many other utility companies out there who are more honest, transparent and actually care about their customers.

I spoke with Natalie Team OB2 she was incredible. I have ND and am really bad at technology she walked me through it downloading the App, explained how to use it step by step, kept repeating herself, made me feel safe and understood,never got agitated( like other companies) I am so happy with my service she is an inspiration to other colleagues to do well. Please tell her that she did good and thank you so much Natalie for being there for me.

**I am writing this review following a complaint that has been resolved with the assistance of the Energy Ombudsman - It is not your typical scenario, I'm providing this review to provide visibility of Eon's resolution management**

When I closed on a purchase of my new home, I discovered a meter had been installed illegally and reported it to Eon. Initial interactions with the team were slow at first, as stuff were unable to understand that the meter in the property did not match their system. But this would not be the biggest issue I'd face.

What I have found to be particularly troubling about Eon, is how information between teams/staff is not managed well, details are not shared between staff, and this impacts customers.

Early in the process my case was being managed by a very polite staff member, who was learning how to resolve my particular issue for the first time. I was happy just to have the issue addressed, but what I didn't know at the time was that the staff member was not being transparent with me. I was told an engineer would be visiting the property to inspect the meter and check for safety of installation. When visiting, the staff member called themselves a service engineer, so I was under full understanding that this was the case. But this was not true, thanks to the ombudsman report, I learned that the staff member who attended the site was actually an enforcement officer who was simply there to verify if a warrant based enforcement process was necessary.

I had remained in contact with Eon throughout, initiating calls on a daily basis, the problem with the escalation to a warrant based enforcement process is that it cut communications between myself and existing members of staff, and I had to work with a new team who were not familiar with the details. I was forced out of the case and had to start over. I learned about the escalation by receiving a hand signed note through my letterbox two days later, informing me that Eon were applying for a magistrates warrant to gain entry to my property to replace the meter.

This is an example of the type of breakdown communication I faced, and the impacts it had on me as a customer. I called Eon immediately, I managed to get the warrant request lifted - but I did not manage to get the field services engineer to return despite it being within the hour. I still find it shocking that, despite it being a significant safety issue that a magistrates warrant was required, I did not get to see a field services agent until 25 days later. And that a field services agent wasn't able to resolve the issue on their first visit, that it took over 30 days for a compliant meter to be installed. I felt like I was driving the urgency of the matter, but Eon used the 'urgency' as a means to justify impactful behaviour.

my experience as a customer was not considered, for example, I did not appreciate the threat of a magistrates warrant when I remained forthcoming to resole the issue. This caused me deep distress, I communicated this to Eon and they apologised. However they would go on to threaten me a second time after I missed a single phone call (despite having been accepted all other calls and remaining active on email). There was not a seconds hesitation to threaten me with this process for a second time, despite all the efforts I made to avoid this. Even though I was told the warrant was not against me by name, I still didn't want my newly installed locks/front door to be broken into unnecessarily.

Eon continually had gaps in details, my meter was inside the property at 13ft high, above a door. Despite having told staff this, two visits occurred where staff did not bring the appropriate size ladder, which pushed the resolution of the meter back. When they did bring the correct ladder, they didn't use protective clothes and scuffed my newly painted walls.

Customer experience, communication and information are not the only pain points, unexpected and ambiguous costs are also significant. During this whole period, I went to extreme lengths not to use electricity for safety purposes, living at a nearby relatives home. Despite communicating this to EON, they issued me 'unmetered charges' of approx £68 for a month without clear explanation, they charged me a £30 'start-up credit line' when I asked to be moved from prepayment account to a credit account (which doesn't make sense as these are for when you move to a prepayment account, not out of one). I was then threatened with debt collective action for these fees if I chose to report them to the ombudsman. Beyond shocking.

My experience with Eon has been extensive, I don't have the character limit to include all the red flags here, but I will say that be very careful selecting them as your electricity provider. Staff are friendly, but the processes are disproportionate.

Awful service. I have you 2 weeks notice to us moving house and yet 8 weeks on having moved since we still don’t have the EV tariff we raised beforehand. We’ve accrued a substantial bill and every time we speak to EON they give us a different reason as to why there’s been no movement. First of all we had to wait 20 working days for the system to retrieve data. Then they told us they couldn’t even reach it (AFTER THE 20 DAYS). Then they asked us to book an appointment to get it looked at, then they ran into technical difficulties booking the appointment and told us to wait 10 more days. We filed a formal complaint weeks ago and have not heard back about any compensation or understanding. Useless.

Updated 9 June 2026. Finally got some good news. Shuaib has managed to sort out the billing and i now have detailed bills. Now a happy customer

Joined two months ago on a smart tariff. I’ve paid made 3 payments totalling almost £270 and I can’t get a bill for my usage. I’ve spoken to the customer service team twice and they say it can be sorted and then nothing happens.
I just want to know how much electricity I am using day and night and to pay for what I am using

ENOUGH IS ENOUGH!

After 16 years with E.ON Next, I have finally decided it is time to move on to another energy provider.

About a month ago, I contacted E.ON Next to check whether I had been placed on the fixed tariff I was promised when they installed a smart meter in my home. To be clear, that fixed tariff was the only reason I agreed to have the smart meter installed in the first place.

Since then, I have repeatedly checked whether that fixed tariff had actually been applied and upheld until the end of April this year. E.ON Next said they would try to find the phone call where this was discussed, but... how convenient, they were unable to locate it.

Their solution? They agreed to look back 15 months, find the cheapest fixed tariff available during that period, and put me on it.

Sounds fair? Not quite.

They only applied it for one month, because apparently before 3 June I had to choose a brand-new tariff anyway. So, for E.ON Next’s mistake, and after all the inconvenience caused, I received the grand reward of one single month on a cheaper tariff before being pushed straight back onto a new full tariff.

Naturally, they refused to keep me on the same tariff. Because why properly fix a mistake when you can technically do the absolute minimum?

So now I will choose the more expensive tariff, pay off my arrears, and then leave E.ON Next after 16 years as a customer.

Sixteen years of loyalty, and this is how it ends: with a smart meter I only accepted because of a fixed tariff that somehow disappeared, a missing phone call, and a “solution” that lasted one month.

Congratulations, E.ON Next. You finally gave me the energy to leave.

Absolutely amazing service, sorted my complaint out with such passion and really wanted to get it solved for me. Ash is such a polite and lovely member of staff and I really appreciate all the help and service on the phone.
