OVO Energy Review Summary
Last updated: 21st March 2025
Who are OVO Energy?
OVO Energy was founded in 2009 with a focus on providing greener and cheaper energy services.
They put a strong emphasis on simplicity, so if anyone finds navigating energy suppliers and tariffs difficult OVO Energy could be the supplier for you. Electric and gas services are available throughout the UK on both pre-payment tariffs and credit tariffs on both fixed and variable rates.
OVO Energy proudly promotes the fact they offer 100% renewable energy, so people wanting a greener more environmentally friendly supplier will find OVO Energy to be a great choice. They stopped using REGO certificates (Renewable Energy Guarantees of Origin) in 2023 because they view those as Greenwashing. Ovo Energy aim to be net zero by 2035.
However, OVO Energy only offers 100% renewable energy on its Greener Electricity tariff which is an 18-month fixed tariff with a £75 exit fee per fuel. Having said that, a “Greener Energy” upgrade is available on their other tariffs.
They also offer a variety of other products including upgrades, electric car services, smart storage heaters, and home energy storage.
Octopus Energy offer £50 credit if you sign up through a referral link.

What tariffs do OVO Energy offer?
OVO Energy offers a variable tariff with no exit fee and no minimum contract term. The prices are reviewed every three months.
In terms of fixed tariffs, there are three one-year fixed-rate tariffs. One is a basic fixed-rate tariff, one includes boiler cover and one includes the “Greener Energy” upgrade automatically. There is a £50 exit fee per fuel for each of those tariffs.
If you’re happy to fix your price for longer there is also an 18-month fixed-rate tariff with a £75 exit fee per fuel and a 24-month fixed-rate tariff with a £95 exit fee per fuel. The 24-month tariff comes with a free smart thermostat.
There is also a free add-on called Charge Anytime for electric vehicle owners. Despite the name, Charge Anytime means that if you have a compatible charger and charge your electric vehicle when the electricity is greener, you get charged less. However, if you need to charge your electric vehicle in a hurry you can still do that, although you’ll pay your standard per-unit rate.
How do OVO Energy compare on price?
OVO Energy rarely offer one of the cheapest tariffs on the market. Generally, from our research on comparison sites, they sit around mid-table in terms of price.
Which? Currently only rates OVO Energy as 2/5 stars for Value for Money, which is down from the 3/5 stars that Which? were giving them the last time we reviewed Ovo Energy in July 2021.
What do other OVO Energy reviews say?
OVO Energy perform well on third party review site Trustpilot. They have over 197,000 reviews and an overall score of 4.5 out of 5 which is up on the 4.3 score that they had last time we reviewed them. 73% of reviewers rate them as Excellent with only 10% rating them as bad.
In the latest survey by Which? covering the July – September 2024 period, OVO Energy came 13th overall out of 18 energy suppliers with a customer score of 59%. This was down from the 70% score that they had last time we reviewed them, and is below score required for them to be a Which? Recommended Provider.
It’s a slightly better story from Citizens Advice where for the period covering July – September 2024, Ovo Energy came joint third out of 16 energy suppliers with 3.6/5 stars. Utility Warehouse and E came joint first with 3.8/5 stars.
What is OVO Energy’s customer service like?
OVO Energy offer reasonably good open hours at Monday-Friday 8am-8pm and 9am to 5pm on weekends. According to Citizens Advice they are currently answering calls in one minute and 20 seconds.
There’s also live chat via the Ovo Energy and you can contact them via email. According to Citizens Advice, they respond to 96.7% of emails within two days, an improvement from the 86.9% response time last time we reviewed them.
When it comes to complaints, Citizens Advice gives them 2/5 stars as Ovo Energy receive a fairly high number of complaints at 54.6 per 10,000 customers. This nearly double the 28.1 complaints per 10,000 customers that they were receiving last time we reviewed them.
In 2024, an Ofgen investigation into complaints handling at Ovo Energy resulted in Ovo Energy having to pay £2.37m in compensation.
Ovo Energy operate a Guaranteed Standards of Performance guarantee which means that they’ll pay you £40 compensation if they let you down.
What is OVO Energy’s website/app like?
OVO Energy’s website is clean and modern which makes it easy to navigate and find the information you’re looking for. The help and support section, in particular, is worthy of praise and so is the discussion forum. We have seen other energy suppliers provide a discussion forum, but this is one of the best we have seen in terms of design and user activity.
OVO Energy has an app available for both iOS and Android devices. The iOS app is highly rated, achieving a 4.7/5 score from over 15,000 reviews. However the Android app currently only has a 3.5/5. This is much lower than the 4.5/5 score last time we reviewed it and it appears that a recent update has not gone down well with Ovo Energy’s Android customers.
How green is OVO Energy’s energy?
If you want green electricity, you need to upgrade via OVO Energy’s Greener Electricity option. This costs £8/month with £40/year of that being spent to supporting new independent UK generators.
If you upgrade you will be using genuine renewable electricity that is purchased via Power Purchase Agreements rather than “greenwashed” energy that is green via carbon offsetting.
If you don’t upgrade to the Greener Electricity option, 65% Ovo Energy’s electricity comes from:
- Natural Gas – 61%
- Coal – 13%
- Renewables – 11%
- Nuclear – 9%
- Other – 6%
Below are a few quick questions you may need answers to along with our OVO Energy review:

Terrible company, been trying to get resolution for billing for almost 2 year. We have a complex supply in that we have economy 7, the left at OVO doesn’t know what the right is doing, Staff fob me off with every call. Holding now trying to speak with resolutions team, been on the call for almost 35 minutes and been on hold at least 20-25 minutes. Would definitely NOT recommend OVO. The call last over over an hour in total with with 50 minutes or so on hold, still no resolution and will not give me timescale to solve, just saying as unbilled for long period they don’t have to give a timescale!! Appalling.
Ovo informed me after making regular monthly payments that I owed them £1400 in electricity due to a technical error on their end. I of course said wipe that debt as it was a fault in there end and o have been paying in good faith. I opened a customer complaint and was assured this would be done and I’d here nothing more. March comes 3 months later. They put my account into -£961, and informed me they have given me a 10% discount. In the email explaining this it states ‘due to a technical error’. I have paid monthly I have paid in full and now am told, because someone in there company made a mistake I owe them a huge sum of money. Single mum of two children in a pandemic who has never even paid late let alone missed a payment. Disgusting and legal action will be taken.
Do not sign up to @OVOEnergy called ‘trying to save me money’ telling me to adjust my boiler, this then racked up a debt of £360 on top of normal usuage which they admitted was a member of their staffs fault but still expect me to pay. Not genuine don’t trust them
Ovo are rubbish at customer service. They have been promising a meter change (faulty smart meter) for 18 months (Excluding Covid period)and failed in every expected respect of their promised service. This is a zero star company!
I was forced onto OVO because my old supplier Economy Energy went bust. I was forced to stay with OVO for 6-7 months. I was stuck on a variable high tariff waiting for OVO as they refused to allow me to switch providers or change my tariff and I was never in debit. They owe me £375.95 plus interest. I base a company based on their customer support in this case my complaint was ignored for a year a whole year.
