Our take

On average, home energy represents 26% of our carbon footprint. Ovo Energy wants to bring this to zero by providing cheaper, greener and simpler energy to customers. It's analysing meter data to deliver easy, personalised actions, turning electric vehicles into power stations with clever chargers, and building energy-efficient heaters. For households, it's offering is organised into four different energy plans, that include interest rewards on energy credit balance.

In 2020, OVO completed the acquisition of SSE Energy Services' retail arm for £500 million, meaning that the challenger brand now has around 4 million customers in the UK.

While helping Ovo members halve their carbon footprints, the company is also working towards becoming a net zero carbon business by 2035. The challenges ahead for the company include encouraging consumer behaviour change, shifting towards subscription models for home energy use.
