OVO

One of the UK’s largest energy suppliers with competitive fixed deals and strong sustainability commitments.

Ofgem’s price cap for Q2 2025 is set at £1,849 a year for a typical dual fuel household, still well above pre 2022 levels.

OVO Energy was founded in 2009 and has grown rapidly, particularly after acquiring SSE’s retail business in 2020, to become one of the UK’s largest domestic energy suppliers. OVO has made bold sustainability commitments, including planting trees for every customer and driving towards net zero operations. Its tariff range is competitive, with fixed deals that regularly undercut the bigger names.

Is OVO Energy a Good Choice?

OVO’s Plan Zero commitment targets net zero carbon emissions across its business by 2030. All electricity supplied is 100% renewable. As part of their carbon programme, OVO plants trees on behalf of customers, typically claiming to offset the equivalent carbon of an average household’s energy use per year. Independent environmental groups have questioned whether tree planting alone constitutes genuine carbon neutrality, and OVO acknowledges that their gas supply remains conventional. For customers primarily interested in the electricity carbon footprint, OVO’s REGO backed supply is a solid choice. For those who want to also address their gas emissions, their green gas add on is an option at a higher unit rate.

OVO Energy’s Environmental Commitments

OVO has invested heavily in smart home integration, positioning itself as a tech forward energy supplier. Their OVO app allows real time consumption monitoring for smart meter customers, with recommendations on how to reduce usage based on your consumption patterns. OVO Drive Anytime is one of the market’s better EV charging tariffs, offering a cheap overnight rate specifically for EV users. Their Greenlight feature shows customers the relative greenness of the grid at different times of day, encouraging usage during high renewable periods. OVO also offers a battery storage integration product that can automatically charge from the grid during cheap overnight windows and discharge during expensive peak periods, most useful for households that have had solar or battery storage installed.
