“Dreadful company. They seem incapable of sorting the simplest of problem. i have had three different people assuring me that they had each resolved access to an account and yet, days later, and the problem remains. And getting to speak to someone from complaints feels harder than gaining an audience with the Pope. I really don't know why any customer stays with them.”
“Ovo will put you in debt. They can't even manage to send out gas bills, despite me having to manually send meter readings myself. 12 months this has been going on for now. All they do is tell you lies and do nothing. AVOID at all costs, they are absolutely useless.”
“Moved in to my flat in September when I phone to set up my account they insisted that I had a top up meter and wasn’t looking correctly. When they noticed I didn’t not in fact have a top up meter I was informed the meter wasn’t working correctly took them 6 months to fix and then end up have £1,400 electric bill to pay. After paying it off little by little they then informed me by email that I need to pay off the remaining £1,000 in 3 months and wanted me to pay £336 a month for my electric which is almost the same price as my rent.”
“OVO are the worst company i have ever dealt with.
They send threatening letters saying i havent paid BEFORE i receive the bill.
When you write to them you get what must be an AI robot reply that doesnt cover the point you raised.
I am going to switch supplier.”
“I gave never in my life dealt with such an incompetent company. They insisted no one lived in the property as(they say) no electricity has been used, yet still took my monthly direct debit. Then they queried my meter readings, and I had to send them photos of my meter reading. They sent an engineer to change over my RTS meter, all went smoothly until engineer left and I realised he hadn't changed over the gas meter, as he hadn't been told to Now have to wait 6 weeks for an engineer to come out again to replace gas meter.
I am 73 years old, suffer from anxiety and have been in tears trying to get this resolved.
DO NOT TOUCH THEM !!!”
“I've now been waiting 6 months for a smart meter to be installed by these cowboys. Engineer didn't turn up again and didn't even bother to phone. To make things worse they are charging me extra for electricity because I don't have a smart meter”
“If I could I would give 0 stars, worst energy company ever. The way they treat their customers is disgusting i phone up to pay a bill and they took payment and told me this was all sorted to then be chased with a debt collection letter chasing payment a week later. I have a young baby at home and we have never missed a payment to then have this treatment is horrendous my partner called this morning and they advised that they did mess up but have put the debt collectors on hold even though this isn't our fault! I think we will be looking for a new provider as the stress in this day and age is not worth it.”
“Ovo overcharged me for my energy for over two years. When I switched provider I was almost £1500 in credit and I’m still waiting to get my money back weeks later. Tried to speak to a human but no difference between the service from the bot and the apparently human advisor who appeared to have a script she couldn’t deviate from. The company is a shambles, avoid.”
“Just received my first monthly bill of £110. I live in a one bedroom flat and have not even been using any heating. Absolute ripp off charges. I will be leaving OVO asap. No wonder everyone gives them one star reviews!! Zero stars if it was possible.”
“Please avoid considering this energy supplier at all costs. My father was charged twice for the same bill (Ovo Energy sent the same bill twice, and threatened to take legal action if he did not pay the same bill twice). Sadly, without double checking he ended up paying it. After contacting their customer service, they promised to provide a refund (a cheque in the post, which never arrived). After contacting them again they decided to credit his Gas and Electricity instead of refunding his money. This has happened on two occasions. We are now considering other other Energy suppliers.
My own horrendous experience with OVO Energy included topping up the electricity on my Smart Meter (Pay as you go) Via the OVO Energy app. The money was deducted from my account and unfortunately my Smart Meter never updated the amount I had topped up. I send evidence to OVO Energy including bank statements and confirmation from the bank that a payment was taken from my account to top up my electricity. OVO Energy first refused to provide me with a refund and later stated that the refund is pending with the bank from their end. As a result of all this my Smart meter started using up emergency credit in the end. Until this very day the money has not been refunded. Very disappointed!”
“Absolutely terrible. They have caused us nothing but upset and stress, the worst energy company you could possibly use. Have been ridiculously unhelpful.”
“Reading these reviews has been no surprise.
I recently left a review on trust pilot, regarding administration failures.
Setting up took a lot of time as I was unsure who was supplying my energy, subsequently accruing a debt.
A plan to pay the debt over the maximin two year period was agreed and a direct debit set up, this was doubled the following month meaning I had to cancel the direct debit to pay monthly agreed amount.
this has resulted in constant calls and messages
No messages sent through to complaints have been answered.
Yesterday I put a negative review on Trust Pilot
The response was to increase my payments even more.
OVO is not merely incompetent but downright nasty in their dealings with customers.”
“Hi,
A truly terrible experience with OVO Energy recently, I've have problems regarding my prepaid key I tried to top-up my key on the 29th May,but it didn't work so got home tried and it on my meter to see if any problems there, it says "ERROR 62" so I contacted ovo to sort this and they arranged for me to pick up a new key from a local shop but guess what? The shop doesn't do that sort of thing then I contacted ovo the following day regarding this matter and they said they'll send me a new key in the post. I'm still waiting ! Today's date is 7/6/25. Ovo are more interested in pushing their Smartmeter on to people than actually helping.”
“I am shocked. Even after I won my case with the ombudsman and been awarded compensation, Ovo lied to me again saying the compensation that they were ordered to pay ,would be paid. I have received nothing.
Total nightmare.”
“1) OvoEnergy has completely wrecked a fair and accessible system since taking over from SSE. They didn’t ask SSE customers if they wanted to change — they barked orders. They forced everyone to fall in line with their own Ovo Energy customers and their digital-first business model, knowing full well that if they had asked, most SSE customers would never have agreed to it.
2) I personally relied on giro slips and a plastic top-up card I could use at local shops — it was easy, familiar, and it worked. But Ovo stripped that all away. Now they demand you use an online app or card payments, cutting off the payment methods many people depended on.
3) To make matters worse, their online app is more expensive. They claim it’s not, but they’ve found a way to manipulate it — showing that you're using more energy than you actually are, making it feel like your account is always just behind. It's a sneaky way to keep people topping up more often than they should.
4) This wasn’t a fair transition — it was forced, and it was calculated. They’ve taken away choice, manipulated the system, and ignored the needs of thousands of loyal customers. I hate what they’ve done, and I’d never willingly stay with OvoEnergy if I had a choice.”
“Firstly, their standing charge is much higher than other suppliers and their unit charges are higher too. Secondly, they make A LOT of 'mistakes' with billing, always in their favour. Finally, when you raise issues you are gaslighted and lied to, no exaggeration.
It was shocking. Luckily I could prove Ovo were in the wrong and they eventually set my account to zero. The happy ending is I left Ovo and am now with Octopus, my bills have fallen and I'm not being treated like a commodity to be bled dry.”
