Ovo Energy

Ovo Energy started out in 2009 and has since grown to supply more than 4 million homes across England, Scotland and Wales.

Its Path to Zero plan aims to help customers reduce their energy bills and collective carbon footprint. Customers can also win a year's free energy by using energy at greener times of the day. 

The company invests in smart technology, including trialling vehicle-to-grid chargers, by which excess power stored in electric car batteries is sold back to the grid.

SSE Energy Services customers moved to Ovo Energy in 2023, after Ovo Energy bought SSE's domestic customers. Pay-as-you-go brand Boost Power was also part of Ovo Energy. Its customers moved to Ovo after the parent brand announced its pay-as-you-go arm was closing down – also in 2023.

• Pros: Scored well for its customer contact setup and providing help for those who need it in our behind-the-scenes assessment
• Cons: Poor value for money and poor in all other areas, according to our customer survey

Ovo Energy customer review

Ovo Energy got the lowest score of the 17 energy companies rated by 11,945 members of the public in the annual Which? customer survey this year. 

Scottish Power was the only provider to receive a similar score, with 62%. The next highest was 65%.

Ovo Energy had poor two-star ratings for every aspect we asked customers about, including for overall customer service, customer communications and value for money. 

One unhappy customer said: 'They didn’t resolve my issue and completely ignored my complaint.'

But there were positive customer comments, too. One said: 'They are helpful, efficient when assisting you and go the extra mile to resolve your issues.'

Ovo Energy customer service

Ovo Energy received a poor two star rating for overall customer service. It was one of eight providers out of 17 to receive such a low score.  

One of its best ratings in our supplier assessment was in the contacting your supplier category. Ovo Energy came joint second with eight points, scoring the same as Octopus Energy, Co-op Energy and Outfox Energy in this section.

Customers have a range of ways to get in touch with Ovo Energy, and its self-service online help is good for common questions. On the downside, its customer service phone line is open for shorter hours than some other firms'.

Ovo Energy common complaints

In our survey, 5% of Ovo Energy customers who said they had contacted the company in the past year did so to make a complaint.

The most common problem experienced by all Ovo Energy customers was their direct debit payments being set too high or low – 9% said they had experienced this in the past 12 months.

Our Ovo Energy supplier assessment

In September-November 2025, we looked at five aspects of suppliers' business practices and procedures. Examples of some criteria within each category include:

• Contacting your supplier – including how and when you can get in touch, call waiting times and the quality of self-service help online
• How well they deal with complaints – how many complaints suppliers get and how quickly they resolve them
• Supporting customers who need it – including web accessibility, those in vulnerable situations, those who use prepayment meters, and those who need materials in languages besides English 
• Switching – how well suppliers handle switching
• Smart meters – including performance against 2024 smart meter targets and the proportion of customers' smart meters actually operating in smart mode.

We did this using a combination of the responses to a survey we sent to suppliers and our own assessments.

Ovo Energy's 60% score was just below average. Most other big firms, including British Gas, Scottish Power and EDF Energy scored lower, while E.ON Next and Octopus Energy scored higher. 

Its best score in our assessment was for helping those who need it, where it achieved 9 points out of a possible 10,  although several other firms did just as well or better. It also scored well when it came to its methods for customers to get in touch and its self-service options. 

Ovo Energy didn't score so well when it came to how it deals with complaints, with just 6 points out of 15. The top scorer here, E (Gas & Electricity), achieved 13 points.

How sustainable is Ovo Energy?

Sustainability credentials are important when choosing an energy supplier for two thirds of those responsible for choosing their provider. That’s according to our online survey of 3,000 UK adults in August 2024. 

So we factor in a range of sustainability criteria in our Eco Provider assessment. We are next running this research in 2026.

Here’s how Ovo Energy fared:

• Proportion of renewable electricity sold to customers: 11%. 
• Ovo says that this fuel mix 'might appear less favourable than others on paper', because it does not buy REGO certificates which allow suppliers to match renewable power to their customers' use. It says these 'don't generate any more green energy'.
• Does not generate renewable electricity but buys it directly from renewable generators for customers who opt for Greener Electricity. 
• Offers a range of tariff add-ons that reward customers for shifting their electricity use to less popular times, or when there's a lot of renewable power available. These include: Power Move challenges where customers can earn credit for using less electricity at certain times, Shift and Save where customers earn credit for reducing their consumption compared with usual at times of high demand on the grid.
• Offers installation of solar pv, battery storage, heat pumps, insulation and EV chargers.
