“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.”
“Reading one of Anonymous reviews below is exactly like my own experience (it's you £75 person). Exactly where I am now. I imagine plenty of older people or those who are unable to confront them are being ripped of and money taken when it shouldn't. They will not get my custom again.”
“Terrible service, reported i was moving out of my property and they closed the account then reopened it claiming I still stayed at my previous address and continued to refuse to refund my credit amount and bill me on charges despite power off. Discussed many times with customer service and emailed complaints but they won't stop. My daughter has pay as you go meter also and they have been billing her also monthly and refuse to stop. Scammers for sure would never use again please avoid!!”
“Awful service for my 83 year old mother. They have left her without working hot water and heating for 8 days and have said they are waiting for a part and can’t repair until Tuesday.
She maybe £50 a month for the privilege too!
Avoid the boiler repair care at all costs!”
“Thieves .. had terrible service from ovo, including total power cuts as they mixed my address up with a neighbour. Finally swapped supplier. A week later ovo decided to higher my direct debit by £50,take it from my bank, then tell me I had to wait 10 days for a refund. Plus wait for refund of over payment. Hard work dealing with them, no English call centre. I would never recommend ovo as a supplier.”
“Asked for opening meter readings by online account, but account not accessible. The app doesn't work and even the auto phone meter reading is not working. Had to chat to South Africa for half an hour to get the readings entered..”
