very unhappy and feel so unwell after I made a phone call to e.on who prior to this has been a very friendly personal service. I explained my car had been in a accident in December when I phoned in January as I was in credit at this time, but was unable to pay my direct debit in December, I was told don't worry as I was in credit and a payment who just start again January. No attempt was made according to my bank in January, so I phoned today after insuring my DD was set up to pay a bit more each month.. it's getting warmer so I won't be using gas so I should be back in credit soon. When I phoned e.on to check this was set up I felt like scum by the end of the call, it was a call centre in south Africa and he lectured me about my debt and how this will impact on me. Very unhelpful, very upsetting, and going to put a review on trust pilot for disabled people. As soon as I am in credit I will look for another provider. I have always paid my bills and this was not taken into account. I'm so poorly and felt like I was going to have a heart attack following calls and kept saying to call handler it was making unwell.. many thanks, poppy patey , .

I made the switch to Eon on the next drive tariff, only to be told a few weeks later I can't be on that tariff and the had an error. No real communication or reason was provided. I had been charging my car which means they will be charging me the full rates instead of the rates offered when I made the switch. Also it's is hard to communicate and get a resolution. This feels like another big company that takes advantage and can't deliver on what was signed up to, also very poor customer service during this issue.

Do not sign up to the eon next drive smart tariff, nothing about it works, nothing but stress and failed charges. God knows whether I'm even being charged off peak rates when the app creates a schedule- the app never recognises that the car is plugged in.
Contacted customer services twice and still no resolution

He was very grateful

We have purchased a property and the electricity there has been disconnected, because the previous tenant didn't pay his bills. It's been 3 weeks now that I have contacted this company on several occassions and have done everything they asked us to do, we have sent all the necessary documents to prove that we are the new property owners as well as documents from the new tenant proving that he now occupies the property, they took ages to answer and now they have a problem to send an engineer to reconnect the meter. Instead, they have been sending letters to our address under the previous tentants name that left over 2 years ago. The new tenant agreed to pay the reconnection charge and deposit to open a new account and now they say it will take another 3 weeks for them to come and do it. They don't care about the loss off business, the customer service is the worst.

They have made three appointments with me to install smart meters, every time I have booked time off work but then the engineer does not turn up, today a lady called Michelle from Eon emailed me to say she will call me at 4.30pm to discuss why I have been let down yet again and she didn’t even call me! I will be changing my gas and electricity providers because Eon have done nothing but let me down

Great engineer, all done professionally and tidily. Went through everything after installation.

The only thing they need is your payment on this and rest you have to chase. Pathetic service

Engineer was efficient,, tidy, and explained well.

Money grabbing. The worst company and support I have ever known. No assistance on the phones, and the whole reason the account got into debt was because of their own misunderstanding. Discussed my situation with them and they did not even attempt to support, due to my situation at the time and bwing unable to work, they threatened instead of trying to help me settle the debt, which I agreed to pay in the end due to their threats.

When wanting to close the account they took way over 5 days to give me confirmation.

For your own sanity, do not go with Eon by any circumstance. I will always warn people about their greed and so far 5 people I know have swapped, I will continue to tell people for the damage they caused me, when they easily could have helped me.

Your debt has been paid, you got what you wanted. Scum.

Wallbox EV Charger fitted by E.ON in the last 12 months. The charger no longer works but E.ON keep telling me to contact Wallbox. E.ON supplied and fitted the EV Charger so why should it be my responsibility to contact Wallbox? And the numbers they have given me for Wallbox do not work! Going to be charging any transactions back relating to the EV Charger as it is under a 3 year warranty but nobody is attempting to repair it.

Jason Grey was fabulous. Arrived on time and worked hard. Replaced gas meter as planned also electric meter that hasn’t worked for years. Very professional.

Nice to talk and got a very good and patiently spoken staff with all beneficial services they are going to provide

I am in credit with this company to the sum of423 pounds I have asked them to return 300 pounds to which they refuse I ha e now requested this 5 times.scum bags

Eon energy are Britain's most unhelpful company. Their website doesn't have a "speak to us" section, although if it does, it is very well hidden. I am a disabled pensioner trying to struggle along by myself. I need to URGENTLY speak to EON but there is no one to speak to. I am at my wits end. I really do not know where to go from here and I do not know how to change supplier.

Became a E-ON customer since 2024. I've had over 6 months of issues with E-ON concerning my Gas Account. E-ON accepted my supplier switch, my account was created and payment Electric & Gas each month. Then they cancelled my Gas Account, saying they don't supply my Gas, I wasn't able to upload any Gas readings, I demanded a "Deadlock Letter" enabling me to report them to the Energy Ombudsman and suddenly they have opened the Complaint, which they should never had closed.
6 months later and they are still investigating, I get one story/explanation after another. Complete incompetence and lies.
New Year and they still cant resolve it !!! In the hands of the regulator.

Wayne and Sam have just installed my EV charger and have done an excellent job. Professional, polite, and tidy work — a real credit to EON

Nonn-stop incompetence. Adjusted direct debit, without auth, to way more than the bills we were paying.
Installed SMART meter then sometimes billed us daily, sometimes monthly and sometimes quarterly.
18mths after the SMART meter they announce we owe them £600 because of incorrect readings.
I have asked for my complaint ot be escalated but the agent refuses. I have asked for the complaints process and the agent refuses.
The worst enegry company in the UK. Ombudsman complaint incoming this has been a 2 year nightmare of incompetence. Now our basic rights are being refused.

On 27.01.2026, I had my gas meter replaced with a smart meter. The technician, Marian, was highly professional and attentive throughout the process. He carefully checked everything several times and made sure everything was working perfectly. I’m very satisfied with the quality of the work and his thorough approach. Highly recommend!

This company should wear a mask! The out law - ( unable to write his first name as apparently an offensive algorithm name - you can work it out) Turpin had more scruples! Was out of contract, didn’t know - ok will take the blame. But you would have assumed EON Business would have let me know, but didn’t. Double my tariffs and charged £2 per day, on the standard daily rate. Simply do not care about there long term customers! Shame on you - you stage coach robbers!
