“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.”
“My experience with OVO Energy has been deeply disappointing and feels deliberately exploitative.
When I moved into my property on 14th January 2025, I submitted an accurate electricity meter reading of 9071, which was given to me by my landlord. Despite providing this reading multiple times, OVO completely ignored it and instead fabricated a false opening reading of 6137—a figure they could not possibly have obtained, as they never attended the property. I want to know who gave them this reading.
At the time I switched to a new provider, my gas account had £52 and my electricity account had £57 in credit. To date, OVO has not returned a single penny of this money. Instead, in what appears to be an effort to avoid repaying me, they are now fabricating meter readings and issuing bills based on inaccurate data.
They have only sent a final bill for gas, which falsely shows a debt instead of acknowledging my credit. As for the electricity, I have still not received a final bill at all.
I live with mental health challenges, and it feels like OVO is banking on that to avoid accountability. But I will not stay silent or give up. My landlord is willing to confirm the correct readings, and I will pursue every possible avenue until this is resolved and my money is returned.
This is not just poor service—this is unethical, and I urge others to be cautious.
Roseline”
“Terrible customer service for their solar panels team. I asked for a date when I will be paid for what I have given into the grid (I gave a reading nearly 3 months ago) and was sent a copy and paste of their payment terms. Had my solar panels with ovo since the previous house owner used them, but I would not recommend them to anyone.”
“After submitting meter readings and seeing my account that they owe me for paying extra and when I submitted final metre reading they claimed I was I debt.
Not happy at all,If I could give them no review I would.”
“Since taking over from SSE I have had nothing but problems with OVO.
No answers to complaints incorrect billing for a year, even though I set meter readings in.
Can wait to change supplier. Awaiting review of complaint from ombudsman.”
“"Ovo Energy has shown nothing but arrogance and greed. They’ve scrapped key payment methods like giro slips and the pay-as-you-go top-up card, which many relied on to manage their energy bills in person. Forcing people onto apps and credit cards is not just inconvenient—it’s discriminatory against those who are elderly, disabled, or without internet access. This company clearly doesn’t care about its customers, only control and profit. I’ve had enough of the mess they’ve created—putting profit before genuine people."”
“I wouldn't even give them 1 star if I could.
On the ridiculous prices I paid my final bill then moved go British Gas. On doing so I got a bill of £400 and when I queried it because I had always paid on time, they said it was due to a billing error where they hadn't been charging me correctly. Unfortunately when this happened I had recently had a stroke and said I was in no position to pay it in full or immediately. I got advice regarding it and had been throwing money at it as and when I am able to do so.
Regardless I've been getting daily calls,messages and emails hounding me even though they know of my circumstances and that I am frequently paying.
My partner who doesn't live with me rang up and went mental at them explaining the situation and how I was advised it was unreasonable to spam me as they were.
The person who took the call said she would put a 3 month block on all calls/messages/emails and once that had passed I could get in touch if if it started again.
3 months has passed and it has all started again, I've had to turn off my voicemail as I was getting automated messages left and multiple daily calls. Texts off a withheld number from OVO Energy and one email that slipped through the net claiming I was expected to pay the amount in full on the 25th of April and if I don't pay my details will be passed on.
I used the chat feature and told the person what had previously been discussed, my current situation and that I was paying. And he asked if I wanted to pay the remainder in full..to which I said that's not why I got in touch as I am paying. Then he said unless I set up a payment plan or pay off the money owed the texts/emails/calls won't stop.
I wouldn't recommend ovo to anyone ever. Please avoid.”
“Despite a cadent engineer and a boiler repair man both
saying the meter was at fault when my 94 year old Dad's boiler broke down we had to argue with their customer service centre for 90 minutes to get them to do anything about it. Thank god it was warm this weekend, appalling service from OVO.”
“I was using a Pay as You Go Meter. I was formally a Boost customer before it was moved to OVO, never used emergency credit and as it works, power and gas go off when you run out of the credit your purchased.
I left the property and OVO send a "Final Bill" of almost 400quid. HOW?
What am I being charged for? They said I was accumulating debts, how do you accumilate debts in a Pay as You go system? (The hint is in the name)
I'd never touch them with a 10foot stick and I definitely will share their terrible, exploitive nature to warn other unsuspecting users.”
