E.ON to acquire OVO and put customers in control by making new energy work – for everyone

E.ON Next is already one of the UK's highest-rated energy suppliers on Trustpilot, with a score rating of ‘Excellent’, reflecting consistently strong customer feedback and industry-leading satisfaction levels. E.ON UK is built on financial sustainability, delivering for customers and making new energy work for everyone - affordable, sustainable and flexible.

The acquisition strengthens E.ON UK's ability to deliver value for customers and grow its core retail business.

Focused on the customer

For too long, the energy system has been shaped upstream, around large-scale generation. Consumer flexibility, digitisation, solar, batteries, EVs - and a retailer built to orchestrate them - change that. This is rooted in a simple principle: better outcomes for customers. For customers of both E.ON Next and OVO there will be no change during the regulatory review period and existing tariffs will be honoured in full and service will continue unchanged.

Chris Norbury, CEO of E.ON UK, said: “For decades the UK energy system focused too much on those upstream. Now is our opportunity to change that. Solar, batteries, EVs and a retailer built to orchestrate. That is what this deal is about: customers in control and new energy that works for everyone.”

Consumer flexibility is the key

E.ON Next has built a set of capabilities that put the customer at the centre of the energy transition: time-of-use tariffs that reward customers for shifting energy use to cheaper, off-peak periods; steerable assets such as home batteries and EV charging; and integrated energy solutions designed to reduce bills over the
long term. Together, these turn homes into active participants in the energy system. Every kWh shifted, stored or self-generated is value that would otherwise have been captured somewhere else in the chain. Scale amplifies the benefit - for individual customers and for the system as a whole.

A system built for the future

As the UK energy system evolves, flexibility will be central to keeping costs down and improving resilience. A larger, digitally native E.ON UK accelerates the shift to a customer-led energy system, making new energy work for everyone, not just for early adopters.

Chris Norbury added: “That is the principle behind this deal. It is not about scale for its own sake. It is about building a retailer with the capability, the technology and the customer base to make new energy work for everyone. We chose OVO because it’s a modern digitally native business with great people and a shared belief that innovation is what can make energy affordable and sustainable for everyone.”

“The future of energy is flexible, digital and customer-led. Our job is to make new energy work for everyone.”

Regulatory approval and next steps

The transaction is subject to approval by the regulatory authorities, with clearance expected in the second half of 2026. Until closing is achieved, E.ON and OVO will operate as two fully independent businesses.

On completion of E.ON’s acquisition of OVO Energy, E.ON will continue the existing energy intelligence platform licence agreement with Kaluza in respect of OVO’s customer base. Kaluza simplifies energy billing, reduces cost to serve and enables faster product innovation to support the energy transition. The parties will also evaluate the potential adoption of Kaluza across the wider E.ON group outside of the UK.
