At OVO we are developing the products, services and technology to allow people to transition away from fossil fuels.

We were the first mainstream energy company to remove coal and nuclear from our fuel mix and guarantee at least 50% of the electricity in our standard tariffs is from renewable sources. Through our technology platforms and smart home products we are finding innovative ways to help customers manage their energy consumption and reduce their carbon footprints.

OVO is committed to being a force for good. We are setting science-based carbon targets for both the electricity and gas we supply and our own emissions. We are developing projects to link bonuses with our sustainability performance, to improve access to energy, and make it easier for our customers to lead more sustainable, lower-carbon lives.

There’s a lot of work to do, but we’re determined to leave the world better than we found it.

Boost is a dedicated prepayment energy brand founded on the belief that customers want the freedom to top up their energy when and where they’d like. Introduced by OVO in 2017, Boost is an evolution of OVO Energy’s Smart PAYG+, the first truly smart prepayment platform in the UK. This revolutionary service removed the need for inconvenient card or key top-up systems, instead letting customers add credit through a smart meter-linked smartphone app.

In 2018, Boost launched a new and innovative feature, the Winter Wallet, allowing customers to pay into a savings pot for the winter months.

Founded in 2017, Lumo Energy is an app-only, smart driven energy tariff. Lumo Energy aims to install a smart meter, free of charge, within the first 6 months after sign-up. Customers who book an installation receive a further discount on their energy.
