All about Plan Zero

At OVO, we’re developing the products, services and technology across all our brands to drive progress to zero carbon living. 

Central to this is Plan Zero – our ambitious 10-year strategy developed in response to the climate crisis. Launched in September 2019 it is split into two core strategic areas, ‘Power’ and ‘People’. 

‘Power’ outlines how we’re using our technology to champion the net zero carbon transition, including our commitment to net zero operations and achieving bold science-based carbon reduction targets by 2030.  ‘People’ sets out how we’re going to inspire people to lead more sustainable lives and empower our members to halve their total carbon footprint, also by 2030. 

We are uniting our team, businesses, and members to reduce carbon emissions because we know that reaching net zero is only possible if everyone works together.

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.
