“An absolutely appalling company. Having assigned the supply to my property to a different provider, they proceeded to charge me for usage by a different apartment, issued bills based on estimated readings, did not resolve their lack of connection to my smart meter, did not fully follow the Energy Ombudsman's ruling in my favour and after I overpaid the balance on selling the apartment - having confirmed a credit balance on the account - over 6 months later they assigned an apparent debit balance to LCS Debt Recovery agency. They had also sent debt recovery specialists to an elderly resident in the same apartment block - all completely as a result of OVO's incompetence. Their approach to customer care amounts to harassment and is simply criminal. This company should be closed down.”
“Moved into a property that already had OVO as the supplier, I remained with OVO for just under a month untill my supplier was able to take over the supply. They sent me a final bill on the 15th March, on the 17th March I contacted them via live chat to set up a payment plan. Set up a standing order payment plan, continued to pay this for 2 months, started receiving 5/6 Calls a day from OVO and debt collection letters. I Rang and spoke to lady last week and explained I set up a payment plan and have been paying, she asked for my bank statments to prove this, I provided these via email while on the phone to her, she viewed these and stated she will apply them to my account in 7 working days and I will no longer recieve calls or letters. I asked why it wasnt applied to begin with she stated the bank details that I was provided via live chat were wrong so the money was being allocated to a unamed account instead of mine... she said she had ammended this. Fast forward to today I recieved an email stating they were sending a debt collector to my home and will charge me £20 for the pleasure. I rang again and explained all of the above, the guy said I didnt speak to someone from 'collections' last week it was spmeone from their 'care team'. He stated he could see the bank statments I provided but they hadnt been updated on my account as there was still a collections flag on my account. I stated I was really unhappy, I set up a payment plan 2 days after the account closed and have been paying it every month so to threaten me with debt collectors when its down to their own internal structure not communicating with each other is totally unfair. He replied by telling me how I can file a complaint. He then added he has removed the 'flag' and added my payments to my account so moving forward I shouldnt recieve any more debt emails,calls,letters.
So even if you pay your bill each month without fail they will still try to find a way to do you over.”
“Unfortunately, this company is very disappointing. I had a very difficult time with them; they manipulated the system, made unjustified payments, and charged exorbitant prices. When I terminated my contract, they said there was one final payment due, which I paid. Now, a month later, they're saying I have to pay again. I don't understand why. Even their employees are inexperienced. I wouldn't recommend anyone contract with them.”
“If I could give 0 stars, I would. The customer support is SHOCKING. They hit me with a HUGE bill at the end of my tenancy, which I paid. They then said I overpaid so sent me a cheque for £600 which I cashed. 3 months later, I found a black mark on my credit score because they said I owed them over £1000 because they calculations were incorrect. I just want to be done with this company!!!”
“I tried OVO because it was already installed in the apartment I moved into. I set up a plan and paid for two months, but in the third month I received a notification saying I had no plan. They cancelled it without my request!!! This was the second time I had to spend time dealing with them.
They then set up a new plan for me - though apparently this was “the first time” on their end (how is this possible ha). A month later, I received a notification saying they were increasing my direct debit, which is unfair considering I had already opted for a plan above my actual usage. This option wasn’t offered to me a month earlier?! And had it been, I wouldn’t have agreed.
I had to call again. Third time in 4 months. While I always appreciate customer service teams - nothing ever gets properly resolved here. Avoid OVO at all costs if you don’t want to constantly deal with issues that are outside your responsibility.”
“Heavily in credit with OVO and asked for my money back as credit balances are no longer covered by government guarantee and I was concerned about the company's financial situation. They immediately revised my bills and from being nearly £500 in credit I went to being in debit. A whole series of different explanations followed constantly changing as each one was shown to be untrue. Now they suggest that I wait 3 months before getting my money back. They are clearly in a worse financial position than I thought and I am reluctant to leave my money with them as I don't know if I will ever get it back. If you have a credit balance with this company I would get it out quickly.”
“OVO are making me suicidal
They advise you to work with Stepchange, but ignore the communication OVO advise you to send. They ignore the budgeting sheet. They do not know how to work with vulnerable people.
They call me at 8am everyday & leave voicemails.
If I end my life I want everyone to know OVO are responsible”
“Title: Disappointing incentives and misleading promotions – think twice before joining
I have been an OVO customer since the transition from SSE a few years ago. After several years of loyalty, I feel compelled to share my experience regarding their marketing practices and customer service.
My main grievances are:
The "Power Move" Scheme: I signed up for the "Power Move" incentive, which promised rewards for shifting energy usage away from peak times. Despite participating, I was told I hadn't "signed up" properly, despite having been paid once. When I queried this, I was given shifting excuses about my usage not being low enough. This was particularly frustrating given that my property was empty at the time due to construction, meaning my usage was already at an absolute minimum.
Misleading Promotions: OVO frequently runs promotions, such as "2 free hours." However, the small print includes a strict cap of 1kWh per hour, making the actual financial benefit negligible compared to the way it is advertised. It feels less like a genuine saving and more like a marketing gimmick.
Token Incentives: They also offered a Tesco Clubcard incentive where you could "earn" 100 points per month, but this was capped at a total of 300 points. Since 100 points is worth just £1, the total value of this "incentive" was a mere £3—hardly worth the effort of managing yet another scheme.
Standing Charges vs. Usage: For a low-energy user, the high standing charges frequently outweigh the costs of the energy I actually consume. While this is a broader industry issue, the combination of high fixed costs and ineffective, "gimmicky" incentive schemes has made my experience with OVO very poor.
I am now switching providers. I would advise anyone considering OVO to look beyond the flashy marketing and read the fine print—or better yet, look for a provider that prioritizes fair, transparent pricing over these complex, confusing "challenges."”
“Been with them not even a week & the ovo energy top up app doesnt work. Ive phonwd twice already & after updating my details i still cant change my password because the app wont send a code to my email address!!! Ive tried at least seven times disgraceful!!!!”
“I have had on going issues for around 2-3 months with gas metre pay as you go no credit would go on,always had to go on the phone for a hour to 2 to top upwhen finally sorting they only offered 10 pound as compensation saying the line keeps breaking magically when it came to compensation so had to accept as already been on phone for 2 hours will be looking at changing energy supplier they’re not very helpful and will insist you are doing it wrong when it’s completely they’re fault on there end,the way they would speak to you was so unprofessional,after so much frustration of all this only to offer £10 compensation is an absolute disgrace.”
“I never applied to have energy from Ova. They have been calling everyday to ask me to go through Security questions which I said I didn't want to. One day they a customer service staff put the phone down on me. I complained, when they complaint handler explained that the Property Management company applied on my behalf on the 9th April 26 and said they will reduce the bill the cover a void period when the house I own and was managed by the company was emptied. They said they would prepare the new bill which would take 3-4 days, send it to the Property Management and I have 14 days to pay for it or they would send the bailiff and record with credit agencies. I have not seen the new bill. today 13/4/2026. I have received, however a message on text "To avoid further action, pay today". How can the government licence such a firm to supply energy? I wonder what Ofgem would say about that.”
“Over charges then justified it after many letters and phone calls admitting they owe me £195., They then sent me a dear john letter saying they had under charged me AFTER ADMITTING THEY OWED ME MONEY IN AT LEAST 3 EMAILS... NEVER AGAIN”
“I am extremely disappointed with the service from OVO Energy. I have never had an account with them, yet they continue to send bills in my name.
Initially, they started sending bills in my husband’s name. After he complained, they simply changed the name to the butcher's shop on the account instead of resolving the issue. It is now wrongly in my name, despite us repeatedly informing them that we do not use their services.
A debt collector was even sent to our address. After checking the meter number, it was confirmed that it does not match the account they are chasing. The debt collector also passed this information back to them, yet the harassment has continued.
I have provided proof that my energy supplier is Octopus Energy, including evidence of payments, but OVO has ignored this and continues to send letters and pursue debt recovery.
This situation is not only frustrating but has now started to affect my credit score, which is completely unacceptable given that I have no connection to this account.
Their handling of this matter has been careless, stressful, and unprofessional. I would strongly advise others to be cautious. I expect this issue to be resolved immediately and my details removed from their system.”
“Absolutely awful company! I am over £160 in credit and they have put my direct debit up by £16 a month not even knowing if I can afford it
As apparently next march might be in a minus unbelievably I could be dead by next march and would never be in a minus anyway it's more likely that I'd be even more in credit really awful company I'm definitely changing providers asap”
“Honestly the worst company in and out of energy. Real life criminals. Charged me over £9 a day on days I worked in the office because they say they can tell I had a socket switch on even though theres no plug. charged me £70 in 3 days. Its currently spring and I havent turned heating on and in a week I owe £150 just for gas. I have only been with them a year and honestly nothing good to say. Today is 01/04/26 and as of this year on the begining of the 4th month, I have already paid them over £900, imagine what I will pay by December. I have now switched today and cannot wait to leave these people. please avoid if you can. you will lose less money if you just burn all your cash with literal fire.”
“I left OVO back in December because they kept raising my direct debit based on their own (quite high) use estimates. Even after final meter readings had been sent and final charges applies to the account, OVO continued to collect my direct debit monthly.
I contacted them about this and they said they couldn't cancel the direct debit on their end. Fine, I cancelled it through my bank instead. I then contacted about getting the money they had debited refunded. Can't transfer it to my bank because I don't have an active direct debit. And because they took so much, they also can't do a digital voucher. The only option is a cheque like they're decades stuck in the past.
I am surprised OVO has managed to operate like this for so long in a regulated industry.”
“Left them back in December because they kept wildly overestimating my future bills in order to raise my direct debit. Finally decided to pay the exit fee just to be able to switch, and even after my account is closed, they didn't cancel the direct debit. I tried to do this myself on their portal and the button to manage direct debits didn't work. Tried to do it through their help chat and they ALSO couldn't do it. Ended up contacting my bank. Surprised this company has been allowed to operate like this for so long in a regulated industry.”
“Honestly wrote an email to ovo complaints ! They can’t discuss the problem because the letters they keep sending them with an account number is linked to a different email and phone no .
Yes that’s because it’s not my bill , duh .
But they have my address from somewhere and so even though it’s not my account have harassed me with letters and now debt collection
They are so stuid no one in this company can sort it out !
I spoke to debt collection ages ago and even they sent it back to ovo”
“If you want to be cold due to hardly putting the heating on and hardly use any electricity and get charged £300 a month for it, OVO is the company for you!
Just switched to octopus, I’ll be happy to see OVO go out of business.”
