Empowering your net zero path

At Zenergi, we focus all our expertise, insight and passion on making your journey to net zero feel more manageable. Our approach ensures you achieve your goals faster, more economically and more sustainably.

Zenergi was founded in 2003 by Kevan and Rachel Walsh, who had held senior roles in the energy industry and identified an opportunity to simplify energy procurement for customers. They had a clear vision for the business: to be different from other brokers and consultants, and to be customer-focussed at all times.

Kevan said, “The world of energy is frantic. Zenergi’s ethos was to bring a sense of calm and peacefulness to what could be a difficult process to navigate.”

The business was started with 201 schools and word quickly spread. Schools which were procuring their energy via local authority frameworks had little visibility of their energy costs, making it difficult to budget. Zenergi offered a clear and simple alternative, and increasing numbers of schools turned to Zenergi seeking greater flexibility, with a wider choice of suppliers and terms, and visibility of the costs of the energy they were contracting.

As the number of customers grew, so did the team and the product offering, developing into a fully outsourced energy department for clients including; bill validation, supplier query and resolution, and consumption monitoring and energy-saving advice.

As Zenergi continued to grow – doubling in size in five years, and witnessing 20-30% year-on-year growth from 2010 – word of mouth brought new customers from different sectors and private equity investment to support growth and investment in systems, people, and technology.

The acquisition of SB Energy was followed shortly by Briar Consulting Engineers, establishing an in-house technical services department to offer energy compliance and energy and carbon reduction services.

Additional acquisitions of businesses that share Zenergi’s commitment to customer service came in the form of Power Direct Ltd; Apollo Energy; DB Group (Europe) and Powerful Allies, expanding both the service offering and the sectors served.

Now in our twentieth year of operation as Zenergi, we’re a dedicated team of over 200 energy and sustainability experts. Together, we guide our customers through every stage of their energy journey, from procurement to net zero, and everything in between.

A message from our Director of Net Zero

“From our experience on the ground, there’s a huge demand for organisations to demonstrate progress. But once they grasp the potential benefits and improvements that can be attributed to having a net zero strategy, whilst sharing data and knowledge across the value chain, there’s no slowing down net zero commitments.”
