Welcome to the future of energy

OVO was launched in 2009 with the vision of being cheaper, greener and simpler. From the beginning we focused on delivering a new energy experience with honesty and fairness. And in that time, we’ve been recognised as the UK’s leading energy supplier* – welcoming over a million of you to the OVO family.

But we need to do more.

The UK electricity grid is facing a whole host of challenges. It’s ageing infrastructure is struggling to support the demand for more renewables, and soon it’ll need to face the electrification of our country’s transport and heating too.

For decades we’ve burning fossil fuels to power everything we use at home. But this is simply not sustainable; if we carry on this way, we won’t have a planet to live on.

We believe we have a solution.




Terms & conditions

* We were awarded uSwitch Energy Supplier of the Year after coming first for overall customer satisfaction in the uSwitch Energy Awards 2017. Based on latest independent uSwitch Customer Satisfaction Report. Participants surveyed between 27/10/16 and 01/11/16.

1 If you exported energy to the grid from your vehicle every weekday between 4pm and 7pm, over a year, you could earn £274 (based on exporting power at 5.7kW, for 3 hours, at an export price of 7p per kWh).

We estimate that the average annual cost of powering a Nissan LEAF would be £266.61 based on the following assumptions:

* Average annual mileage for a private vehicle: 7,500 miles (

* Nissan LEAF’s consumption of 4.2miles per kWh

* Unit price of 14.93p per kWh (being the price for an OVO customer on our Simpler Plan excluding regions 17 & 18 where the charger in unavailable)

(7500/4.2) x 0.1493 = £266.61

Therefore, using this example, the estimated average annual costs of £266.61 would be covered by the estimated export credits of £274.

All data and calculations are presented as at 05.04.2018

2 If you’re on our economy 7 tariff, you can schedule your charging so your car only charges overnight on off-peak rates.

3 The battery charges using energy from the grid when electricity is cheap and likely to be lower carbon intensity, and discharges when electricity is expensive and likely to be higher carbon intensity.

Carbon intensity is a measure of the grammes of CO2 emitted in producing a kWh of electricity, and is usually lower for renewable or green sources of energy. Therefore charging at times of lower carbon intensity and discharging at times of higher carbon intensity will help the grid be greener by giving back greener electricity at times of peak demand.

For every unit of electricity you buy, we’ll purchase renewable certificates for electricity from various renewable sources. Visit //www. T&Cs apply.
