Eon next. May have the cheaper tariff but diabolical service. Easy switch - not at all. Despite having a smart meter since house built 7 years ago… what was supposed to be a seamless operation and after switching to an ev tariff to save a penny per kw, I get an automated email advising switching to a standard variable as my house didn’t have a smart meter.

After calling daily to discuss varying problems from payment methods, linking cars and tariffs, the advisors ( multiple ) chose to speak over me repeatedly on calls resulting in 3 separate complaints over 3 days. Eons complaint procedure involves the cause of the complaint to write the complaint and resolve it themselves!

Nothing like a transparent service.

Fortunately I was within my 14 day cooling off period and have returned back to Octopus who offer tariffs with no tie in fees !

Think carefully before you take the plunge towards Eon.

"I am absolutely disgusted with E.ON's incompetence. For the second year in a row, they are trying to charge me for a period when I no longer lived at the property. I moved out on 20/10, yet they are billing me from 28/10 onwards. I have provided proof of my new address (Council Tax bill starting from 27/10), but E.ON continues to ignore the facts and harasses me for money I do not owe. This was supposedly resolved last year, but they have reactivated this 'ghost debt' again. This is a clear breach of the Data Protection Act (processing incorrect personal data) and a failure to follow Ofgem's billing regulations. If this is not cleared immediately, I will be escalating the case to the Energy Ombudsman and reporting their data handling to the ICO. Stop harassing me for your own system errors!"

I was a customer of theirs and I moved out of my house on the 4th of December 2020. Contracts were exchanged and I was no longer the owner. I informed e-on next of this and they sent me my final bill which I paid immediately.
Imagine my surprise when I get a letter from LCS debt collectors telling me they are collecting debts from e-on next and I owe £84.01 from the 4th December 2020 to the 8th January 2021. I did not own that house during that time and it is not my debt. It's scandalous that e-on Next are selling off their debts without even providing the correct information to LCS. LCS by the way get terrible reviews on Trust Pilot for doing the same thing to many other customers - particularly those of e.on Next. I wouldn't go with this electric company as you may run the risk of the same thing happening to you. I can see reviews on here aswell from disgruntled x customers being chased by a debt company for a bill that isn't theirs. What a disgrace. Sort out your debts the right way and don't let someone else chase the wrong people. I don't appreciated threatening letters about something that's nothing to do with me. I am still awaiting a reply with an apology from LCS. Nothing as yet.

Had old meters replaced and my bills have shot up 25%. Worst thing I ever did I even signed up for their new tariff but that's getting cancelled before the 14 days are up.

I'll be moving their newly fitted meters to another provider, been in touch about it and I am not waiting to see what a full month costs its true what they say getting a smart metre fitted just adds a quarter to your utility bills keep the old ones they at least report the correct readings being robbed by EON but not for long when I move it to OVO/Octupus I'd rather be robbed by them!

I am a new customer and my onboarding experience has been easy to the point of actually using and managing my energy. It is an utterly baffling experience. Why do I need multiple apps to manage my energy (with one app currently being depricated)? Why can't I submit my onboarding meter reading? Why can't I configure my home set-up (battery storage, Solar, EV and battery). Why can't I amend my payments given it's summer and I don't use any grid energy. I am leaving my export with my previous provider as E-on is 10p less per kWh in terms of export payment. I am genuinely amazed that (I assume) someone has signed this off as the agreed onboarding and user customer experience. It's really not optimal, to be absolutely frank. I tried to do some in-app feedback and it looks to be deliberately choked off, as part way through it stops with no active field to progress. I left the survey for ten minutes and then it allowed me to progress 🙃. When researching transferring to E-on I put in my car's make, model and charger make and model and confirmed via the website that they were supported. Today the app is telling me those same selections are unsupported. Unbelievable.

0,0,0, I refuse to pay the charges to the brokers who send your bills not the utility company the liars they employ who claim they are your supplier to rip you off , anyway they have just broken the law by tampering with my bank account and credit score claiming I missed a utility payment two months ago this is a lie they are brokers and cannot do this , I checked back 6 months on my account , and every month a payment has been made , I also checked my bills also no missed payments they claim to be eon lenders a brokers firm not ,NOT A SUPPLIER the bank are now investigating and so are trust union I have warned people, cancel your dd and pay through online banking but only your usage and vat ,

E.on called to say they needed to check meters as not sending readings. Day of appointment got a call to say engineer was running late and would be in touch, which he was when 15mins out. On arrival engineer explained what he needed to do and how long it would take etc. very polite and helpful across the company. Professional staff.

What an absolutely useless organsation. I am with EON HEAT - they contacted me to book in the service of the HEAT unit which is due every two years. We booked it in for the morning (9am-1pm) and the engineer failed to turn up. I contacted E.ON and they told me it is booked in for the afternoon. How can you be so absolutely useless you cannot even get the difference between morning and afternoon correct? And the text I received the day before also does not mention the afternoon.

Great experience of installation of two new Smart meters

Worst supplier to deal with, staff do not know what they are doing. Offering products to my 81 year old Mum that do not work in her flat. Never call back, switching to another supplier as they are uncaring

Have tried several times to sign up as a new customer to Eon and set up an account for use with a heat pump unit.
No welcome letter, customers service assistant said they cant set me up as it will have to be done on line! Have filled out the appropriate on line document yet no response.
All the time im being charged at a far higher rate on a tariff the original builder set up.
Thought Eon had a good customer service record, obviously dont need my business. Will look at other speciffic tariffs like Octopus Cosy.
Very disappointed with lack of response to my request.

1 star – Left without gas for days with no real support

I had my gas supply suddenly stop on Saturday, and my gas meter appeared completely dead with no signs of activity. I contacted E.ON support, went through a long list of repetitive and unnecessary questions, and was finally told it was a fault requiring an engineer. I was promised an appointment for Sunday morning.

Because of this, I had to cancel my plans for Sunday, expecting the issue to be resolved.

On Sunday, I received another call and was asked the exact same questions all over again. After repeating everything, I was told there were no available engineers because my case was “not an emergency”, and that engineers only handle emergency situations on weekends. My appointment was then moved to Monday.

This left me without gas for the entire weekend — no ability to cook, no hot water, no heating. This is not a minor inconvenience.

On Monday, the situation repeated itself yet again. Another call, the same questions for the third time, and still no available engineer. I genuinely do not understand why my information cannot be recorded properly instead of asking the same things over and over again.

At this point, I am still waiting, with no clear resolution and no accountability.

Very disappointing service. Being left without gas for days with no proper support is unacceptable.

Had an engineer called Frank just completed a EV charger installation at my property today. His work standard was exceptionally high, he was clean and tidy throughout, explained everything in a clear manner and was genuinely a pleasant individual to deal with. I would recommend him to anyone.
Thank you Frank for all your hard work today.

James from Team Derry FSD36 was brilliant regarding a complicated and awkward matter, he was polite, informative and helpful. Thankyou James, appreciated 🔥

My brother had no electricity for a week and they still not come out to fix it

I was an EoN customer for so long I cannot remember how long. We moved home in October and I can say hand on heart we would not have bought the house knowing the issues we’d have with octopus energy the supplier once said we wanted to go to EoN. All delayed by faulty meters and rogue practices and a bill of £400 per month. They are the worse organisation ever. They bullied harassed and overcharged us sadly the energy ombudsman is no better they are corrupt also. It’s took us 5.5 months to get back to EoN. I’ve been dealing with escalated complaints. A decent guy I thought but now they are blindsiding me. They don’t respond to any emails. The energy ombudsman has gone to ground and the guy there won’t speak and won’t give me information or call me back, octopus won’t give me complaints number or engage and are still bullying us and now EoN who we were loyal to won’t help us. I have begged …pleaded and asked for help from the guy who assisted us at EoN but blind sided … I missed a call back but he just ring engage and I’m having a baffling conversation on their WhatsApp as he’s refusing to talk to me ……so I think we will move again but we are trapped into EoN …. I am disabled. We simply need help to complete our move queries. Bitterly disappointed and abandoned by EoN who we thought were much better than octopus who are cowboys. Don’t get me on Energy Ombudsman. They must be paid by that man Greg Octopus. Look at the unprompted reviews not the smooshed ones .

After being with Eon for years we moved to a smart meter as they said we had to. We live in a 2 bedroom flat and topped up £50 Saturday morning, by Monday morning we were £9 in arrears, so topped up another £50.
I queried with customer service why so much money was used when we averaged £4.50 per day. After giving me the run around for a day, back and forth communications, they still asked me what i wanted - all i wanted was a simple explanation as to why the £50 credit disappeared in 48 hrs. This was my opening question and asked 3 times more.
We had family visiting and were hardly in the property, we didn't use the washing machine which would usually push daily spends up to about £7.
After becoming frustrated that they could not answer the simple question - we have now switched supply to Octopus, very easy to do and now we are paying £15 per week.
Every cloud has a silver lining. We were robbed but now we have experienced how easy it is to switch, we would recommend to everyone, to just look into it.

My experience with E.ON Next has been nothing short of appalling, and I strongly urge others to avoid this company.
They appear to use misleading or unclear terms to attract customers initially, giving the impression of fair pricing and reasonable conditions. However, once you are signed up, the reality is very different. My direct debit was abruptly increased — effectively doubled — without any credible justification.
When I challenged this, I was told my energy usage had increased. This is categorically untrue. My usage has remained consistent, and their own earlier estimates contradict this claim. It raises serious concerns about the accuracy and integrity of their billing practices.
Rather than properly investigating or providing transparent evidence, they resorted to generic responses and failed to take accountability. This behaviour feels deceptive and exploitative, particularly during a time when energy costs are already a major concern for households.
This is not just poor customer service — it points to a wider issue of trust and fairness.
In my view, this is a company that customers should be very wary of. There are far more honest and transparent energy providers out there.

Please be so careful when having a smart meter fitted. We had one fitted at the property we bought and the Eon representative has removed the bonding that kept our house safe.
When I contacted them to say this needed making safe they told me that it was my responsibility and at my cost. Search the forums online and you will see I’m not the only customer who has had this issue.
I don’t have the money to fix this yet so my family (including a disabled child and cancer patient) will now have to hope we don’t get electrocuted if something goes awry without our knowledge.
I wish I hadn’t of had them out to us, we had a safe house before they visited and they are not interested in rectifying their destruction.

Lived at a property for four years with my husband who always paid Eon by direct debit at £155 a month. He was in credit with them when he suddenly left me in November. I rang up and took over the bills and somehow they billed me for £756 saying that's what I had apparently used in the two months I remained there before moving into my new home, when it was just me, even though previous bills had never remotely been this high. I've obviously disputed and I'm still trying to dispute this three months later. Absolutely shocking! My new property I've been using less than £100 a month doing everything I was in my old home.
