EON Reviews 64

Worst Energy Provider
This company seriously needs to be investigated and I will be writing to the Ombudsman and also BBC Watchdog.
They threaten you with ridiculous increases in your bill then demand payment via massive monthly increases. They don’t work with you, threaten you and really just should not be allow to trade.
In 3 months we have been charged over £1,000, the majority on electricity, even though we both work full time, turn off and unplug everything we possibly can, use an open fire for heat. I think they just cook their figures and charge what they like.
I would advise everyone to avoid using this corrupt company, they just basically steal money from you.

Can I give zero stars for this company?
After being constantly badgered by them to have smart metres fitted, and I mean harassment on a weekly basis, I eventually gave in and an engineer arrived on the 27th February. After fitting the new metres he told me I would have to continue to submit manual readings as he wasn’t able to register them or set up my in home monitor. I was told they would be in touch to make another appointment to visit again. I have had no contact from them despite me contacting them on numerous occasions. As I need to be in the house for them to visit and I have to actually go out to work and book this time off, it’s both shoddy and inconsiderate. Trying to call them results in lengthy waits (I’ve currently been on hold for 35 minutes)

Got a phone call 17 Feb then a message saying my meter was old you guy's fitted them then 18feb letter and a email same message gets smart meter.Today 24 February
Voicemail then another letter worryed about this one incase it says they are coming out to kill my dog joking I wouldn't put anything past this company literally everyone one of their customers are will get their doors kicked in like mines was and electric and gas meter was changed now they want me to have a smart meter under the 1986 law eon is trying to bully people or they get a telling of from the government remember I ain't. having one Regards Ian.

I received a call today at 15:26 from 0808 501 5338, claiming to be from E.ON, demanding payment — despite the fact that a payment had already been made.
What makes this even worse is that the person they were pressuring for payment is disabled. When we asked to speak to a manager and make a formal complaint, we were told “one moment”… and then the call was abruptly disconnected.
This is not the first time we’ve had serious issues with E.ON. We have repeatedly raised concerns about ongoing billing problems and excessive monthly charges. Over the last three months alone, we’ve paid approximately £1,700 in energy bills — with demands often reaching £400–£500 per month. We do not live in a mansion, yet our bills would suggest otherwise.
Each time we attempt to investigate these charges, we’re met with delays, requests to fill in forms, or told that a manager is unavailable. On this occasion, the call simply ended when we tried to escalate the matter.
We have made it clear previously that unless these issues are properly addressed through a formal complaint process, we will be taking our business elsewhere to a more reliable provider.
Based on our experience, dealing with E.ON has become incredibly frustrating and stressful. We expect transparency, accountability, and basic customer care — especially when vulnerable customers are involved — and sadly that has not been our experience.

So waiting for Eon to explain to me why in September when I asked to be on their supplier and to be on the smart meter. For them to tell me I never had an appointment until the 23rd of December which was made around the 5th to 6th of December so Eon cancelled that appointment telling me that they would find me a new appointment before the 23rd of December after calling on the 22nd of January only to be told no new appointments have been made.

Truly awful humans.

Liars, cheats, incompetence at every single turn. Designed to bamboozle, annoy, antagonise and upset you. Causing huge stress, upset and anxiety is what they do. And it is purposeful. From their CEO office down. Their staff are incapable of basic communication regardless of one syllable words, pictograms in crayon and simple Simon instructions. That. Is strategy. Contempt for customers is mad. Honestly. £4,500 a year i pay these thieves. No more. Switched today. Shameful shameful organisation. Do not trust them with anything. Definitely don't let them put a dumb meter into your house either!

Still no whd and still not blaming the government have a battery problem with my gas man and was told 10 day s yesterday appointment given 27th January go figure

Yet another shameful report on the actions of that absolutely inefficient , incompetent ignorant company - EON!!!

As can be seen from my previous posts my son died suddenly in Middle of February 2025. He was disabled and lived on his own in Housing Association property.

Early in March 2025 I contacted Eon to inform them of this . Cancelled contract, informed them rented accommodation, new tenants moving in, sent meter readings did EVERYTHING I was supposed to do. Spoke to a very nice lady that if money owing I would be contacted straight away as I had to deal with the affairs. Heard nothing until 10 months later !!!! when found a bill amongst my Christmas cards. Asking me to send up to date meter readings!!!! and a bill for £140

Emailed them immediately. Have had emails and posts on here telling me
My email is not connected to his account - no because he is dead

I need his permission to speak to them
He is dead

Contact bereavement centre
Did this March 2025

AGAIN - send new meter readings!!!
Sent in March 2025. New tenants since then!!!

Transfer bill to my name!!!

Just more confused misinformation from an completely irrational, disgraceful company.

I have now escalated the matter to other higher levels. NOT within EON!!!!

There is just not enough space to state what this company has put me and my family through. The worst energy company ever to exist. What they did to my 85 year old frail mother is beyond belief. They sent a debt collector to her home although she was paying her bill every month without fail. The debt collector said "why they sent me round im just not sure as if customer is paying, that should not happen + they sent me all the way from Bristol to London???" Then when they eventually passed the debt onto a collection agency, to date; theyve not sent a receipt for the agreed final settlement of £800+. Leads me to believe that the settlement company maybe a scam company. Im looking to sue e-on.

the worst company i ever dealt with. do not bother, they take money from your account that is not owed

No heating/hot water for my holiday let guest. Eon refusing to come out and they are expecting my elderly guest to troubleshoot the problem themselves , taking a video etc (I don’t live in area btw) - just ridiculous and unacceptable! Emergency weekend Plumber had checked meter and confirmed the issue is with the supplier cutting the gas. (Payments in credit so not the cause!). Raised as a complaint and told it will be 3 days until I get a response. NOT acceptable, especially in October. I will be billing for the plumber call out and for alternative accommodation for my elderly holiday let guest whilst eon twiddle their thumbs in a warm office.

Eon came to fit a smart meter for my 81 year old vulnerable mother. Left her with no electricity after finding and isolating a faulty shower cable. She had no stair lift , phone, lights kettle alarms ringing out as a warning to reconnect. No toilet downstairs with the starllift off. Shocking. Then had to get an electrician in to reconnect. Because the technician never told her to phone eon's emergency number to reconnect at a cost of £120 and alot of stress 😩and worry. I have complained, to no avail.

Like talking to brick walls. Despite numerous emails.containing formation a 5 year old would understand, they continue to ask the questions again. They are saying I owe money from April 2021 despite my vacating the property April 2021 and providing a tenancy agreement to confirm they are STILL sending emails!!!!

Emma SM1 Customer service tenacity and courtesy best i have EVER received. She needs a pay rise. Didnt give up, kept me informed and made our christmas. Superstar A ****** Liam and Stephanie

Don’t get a property where EON are the suppliers. My daughter bought a house that was repossessed. The previous owner owed £4400 and had a prepayment meter that was in debt. She had this removed and pays her bill every month but every month they chase her for the outstanding amount from the previous owners. She rings them and gets told don’t worry, we’ll sort it yet they never do and she is getting very anxious that it will affect her credit score. How can a company this big treat a girl like this!!!!!
