About us

Energise is a UK-based sustainability consultancy founded in 2008 by Simon and Tamsin Alsbury. From the very beginning, our personal mission has been clear: to support organisations to become a force for good – regenerative for society and the planet. We believe that business, done the right way, has the power to deliver not just growth, but meaningful change.

What began as a focus on improving energy efficiency has evolved into a broader, more powerful ambition – helping organisations embed sustainability at the heart of their strategy, culture, and operations. For us, sustainability is not just about climate change. It’s about culture change.

With over 17 years’ experience and a track record advising on more than 7.5% of the UK’s carbon footprint, Energise now supports hundreds of organisations across sectors to drive measurable impact and long-term value. Our work is guided by four key principles:

Sustainable Thinking
We bring a fresh perspective grounded in environmental, social, and commercial understanding. Our consultants help organisations understand their impact, navigate complexity, and lead with purpose.

Strategic Wisdom
We apply judgement, experience, and sector insight to shape practical sustainability strategies that deliver real progress – whether on Net Zero, supply chain engagement, or social value.

Measurable Impact
We don’t stop at planning. We track performance, quantify carbon and cost savings, and ensure that sustainability actions result in visible, credible progress.

Profitable Outcomes
We turn sustainability into competitive advantage – helping organisations reduce risk, lower costs, and create long-term business value.

At Energise, we believe in a future where every organisation contributes to a regenerative economy. That’s why we exist – to help our customers make sustainability work for people, planet, and performance.
