We’re inspiring change in our communities

• Launched the Calisen Impact Charitable Trust - an independent charity that aims to support charitable efforts across the UK, prioritising initiatives aligned with national climate goals

We help the UK meet its climate targets by supporting the rollout of smart meters and other smart infrastructure. We track installations of smart devices against our targets, as we assess how Calisen makes the UK energy system more sustainable.

We will achieve net zero carbon emissions for our operations by 2030 to ensure our business plays its part in changing the energy system. We track the greenhouse emissions created by our operations, the energy we buy, and our supply chain, so we can assess our progress and see where we can make reductions.

We will achieve success together, embracing our differences and enabling everyone to thrive in our inclusive culture. We provide a safe and productive environment for rewarding work where everyone is welcome and we consistently report other diversity profiles of our employees.

We support the economic and social development of our communities and promote sustainable living through training, education, information, resources and charitable support. We support our local communities through charitable support and community projects as well as invest in education for tomorrow’s generation of employees.

We believe doing business isn’t just about what we deliver - it’s about how we show up for our people, our communities, and our planet. Every asset we install, every initiative we support, and every value we live by is a step toward a smarter, fairer, more sustainable future for everyone.

Sustainability is who we are. It shapes the way we work, the decisions we make, and the future we’re helping build. We’re helping families live smarter, greener lives and make better choices for the next generation. We’re creating opportunities for people to learn, grow, and thrive in an industry that’s driving the UK’s low-carbon future.

We’re standing with communities, schools, and charities – not just funding projects, but getting involved, creating connections, and making a difference together. And we’re showing that a business built on values can deliver real, lasting positive impact — for people, places, and the planet. This isn’t just business — it’s a mission, a mindset, and a responsibility we live every day.
