“Poor Customer Service
On 19/02/2026 at approximately 07:00, I received delivery of the EV package materials, including twelve (12) large photovoltaic panels and associated equipment. I had been formally scheduled to receive both the installation engineer and roofer at 09:30 that same morning.
No operative attended.
By 11:05, having received neither attendance nor communication, I contacted your Customer Excellence team to report the failure. I was assured the matter would be investigated and that I would receive a call back promptly.
No such call was received.
I then made repeated attempts throughout the remainder of the day to obtain clarification and secure a revised booking. Despite multiple calls, no confirmed installation date has been provided. This is wholly unacceptable.
The impact of your company’s failure is significant:
Twelve large PV panels and associated equipment remain stored in my hallway, creating obstruction, inconvenience, and potential risk.
Scaffolding erected for the installation is currently obstructing the Sky television signal to neighbouring properties on both sides, creating reputational embarrassment and avoidable neighbour disputes.
I have taken two full days off work specifically to facilitate the agreed installation appointment.
I now face the prospect of taking additional leave due to your administrative and operational failings.
My property remains partially prepared for works that have not commenced, leaving it in an incomplete and disruptive condition.
This sequence of events constitutes a clear failure to deliver services within the agreed timeframe and in accordance with the terms and conditions of our contract. Your failure to attend without notice and failure to provide prompt rectification may amount to a breach of contract and a failure to exercise reasonable care and skill in service delivery.
My required resolution is as follows:
Written confirmation of a new installation date within 24 hours of this email.
A firm and guaranteed attendance date for both engineer and roofer.
Completion of the works strictly in accordance with the contractual scope and timescales.
Confirmation of what compensation will be offered in respect of wasted time, inconvenience, and disruption caused.
If this matter is not resolved promptly, I will have no alternative but to escalate the complaint formally through your executive complaints procedure and, if necessary, pursue further remedies available to me.
I trust you will treat this matter with the urgency and seriousness it warrants.
I look forward to your immediate response.
Yours sincerely,
Stan Grant”
“### Absolute Nightmare: Avoid EON Like the Plague – They Ruined My Business!
If I could give EON zero stars, or better yet, negative stars, I absolutely would. This so-called "business energy supplier" is nothing short of a predatory disaster, and they've single-handedly pushed my small business to the brink with their incompetence, greed, and utter disregard for customers. Stay far, far away from these crooks – they're a nightmare wrapped in bureaucracy and lies.
It all started when they slammed me with a gas bill that was **FIVE TIMES** my usual amount. We're talking an outrageous overcharge that came out of nowhere, no explanation, no warning – just a massive hit to my already struggling cashflow. My business is teetering on severe financial issues, and this bill nearly sank us overnight. When I finally got through to their "customer service" (if you can even call it that – more like a black hole of hold music and scripted apologies), they admitted the mistake and promised a full refund via cheque within 5-7 working days. I begged them to prioritize it, explaining how critical this was for my operations, but did they care? Of course not.
Fast forward past those 7 days: no cheque. Zilch. Nada. I call back, and what do I get? A barrage of lame, pathetic excuses that sounded like they were reading from a bad improv script. "It's in the post," "Processing delays," "System issues" – give me a break! Why on earth would they insist on a cheque in the first place? They could've easily refunded straight back to my account, but no, they chose to sit on my money like a bunch of lazy vultures, earning interest or whatever shady thing they do while my business bleeds out. It's not just incompetence; it feels like deliberate sabotage.
Dealing with EON is pure torture. Their reps are untrained, unhelpful, and uninterested – every call is a soul-crushing loop of transfers and empty promises. They've wasted hours of my time, exacerbated my cashflow crisis, and shown zero empathy or accountability. This isn't a company; it's a scam disguised as an energy provider. I'm done – I'm escalating this to the Energy Ombudsman and warning every business owner I know: AVOID EON AT ALL COSTS. They're unreliable, unethical, and will destroy you without a second thought. Switch suppliers now before they do the same to you!”
“This gives a very bad service. Very pathetic and not recommend for anyone. Keep sending bills without any logical reason and sending someone to the site every other week and charge £65 as visit fee. Completely unhappy and horrible”
“They have sent me a bill 3 years after I left them saying I owe them money which I don’t My bill was paid I got money back after I moved and no longer used them closing my account
Yet they are now chasing me for money which is totally unacceptable
I have found them unhelpful information different each time I spoke to someone different and no one excepting responsibility for there wrong information and disagreeing with what was told to me and were prepared to give me poor credit score if I didn’t pay
Not interested in helping”
“They registered quickly, but when I tried to get my money returned, I was told that trades were holding up. After speaking with one of their agents, I was given the impression that the account would be canceled and my money would be returned; however, this did not happen. I have no means to get back into the account because of this, and I am currently locked out. Thankfully, madacovi. co saved me and all lost assets were recovered”
“Absolutely disgusting company. My Nan is late stage dementia, bed bound, needs 24-7 care, is on the vulnerable list and relies on her carers to live and you didn’t show up for the appointment and refused to get anyone to fix her boiler leaving her without hearing for 8 WEEKS on top of that spoke to my mum like dirt with no regard for the stress and duress this puts her under given it is her ill mother. Not only is it disgraceful to my grandmother, but her carers are amazing and look after her so well it is horrible you’d do this. Your smarmy CS advisor deliberately didn’t help my mum and refused to put her through to anyone else because of company rules. You are horrendous and should be ashamed of yourselves. My mum might not want to leave you a bad review and look in to taking this further but I will. Speak soon.”
“After the winter period ended, that a lot of us have really struggled with because of the energy crisis. I rang EON to refund me the £380 credit I had on my account, now we’re entering the warmer months and I use very little energy at the house. They told me that’s fine, but will need an up to date meter reading before they can issue a refund… this was done immediately as I’m on a smart meter. I then received a mini statement on the account to prove my latest usage and was then told the refund will take 2-3 weeks. Fast forward 2 weeks and my money was still not in the account, so I contacted them again. I was told the money should be in my account within the next 7 days. I’m now at 4 weeks and contacted EON again, only to be told I can’t have my money as they need another up to date reading on my account. What right do they have to withhold my money and expect me to beg for it back into my account.
The other thing to point out is that I had to increase my monthly payments, to ensure enough was being paid into the account, yet I’m still in credit by £100’s already!! Criminal behaviour and again shows how little this energy company think of their customer.”
“One star is too much for Eon. The customer service is non existent, they tell lies and don't know the law. The owe a late relative of mine £500 and have still not paid it back. They created an account in my name and issued wildly inaccurate bills. Who would use £303 for two weeks? I was hounded by 16 debt collection companies, contacted by Philips & Cohen and the Lowell. Eon relish preying on the vulnerable as they are easy targets. The resolution team are too lazy to do their jobs and shut complaints down. AVOID Eon, or as they are known now Eon Next.”
“EON rang me to offer me a new tariff because i am changing supplier after being loyal to them for years.I would have beenmore impressed if they had done so before now”
“Almost impossible to contact, seems they have total disregard for customers, answer times and webchat response much slower than other companies I deal with. Avoid EON if you want a stress free supplier.”
“Been with eon 2 years now. Absolutely crucified me this past year wanting to up my payments to over £100 per month for just myself and my 3 year old! Absolutely crazy! Considering I’m in credit by over £240+. Currently in the middle of a change over to another company. Will never go with eon again! Customer service is also rubbish!”
“I've been an EON customer for 15 years. I reverted to a Standard Tariff after my last 2 year fixed Tariff. I was not offered advice to switch to a better deal. I paid too much direct debit & am always in credit but if I request a refund, this is only done it my direct debit amount is increased!
I have now switched energy supplier on the excellent Weflip! As recommended by Janet Street-Porter!”
“Another shoddy company which are incompetent and unprofessional they always fail to deal with complaints, glad I no longer have them supplying my dual fuel they are money grabbers only interested in ripping off customers.”
