About us

Why is Zenergi different to other energy consultancies?

Zenergi was founded in 2003, acting as an outsourced energy department aiming to remove the complexity of managing utilities.

Celebrating 20 years

Our commitment to delivering exceptional customer service has always been and continues to be central to Zenergi. Strategic acquisitions of businesses that share that same commitment to delighting customers has expanded both Zenergi’s service offering and the sectors we serve, and created an organisation of over 200 energy and sustainability professionals ready to partner with clients on their end-to-end energy journey.

About Zenergi

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.

Zenergi established the first energy and water scheme of its kind with the National Association of School Business Managers. This then evolved into today’s energy framework administered for the association, which is now the Institute of School Business Leaders (ISBL). A partnership with the Association of School and College Leaders (ASCL) and engagement with the Department for Education (DfE) followed, establishing Zenergi’s position as a leading energy consultancy for the education sector. Education reform in the shape of Academies and then Multi-Academy Trusts, brought more customers to Zenergi. School Business Managers recognised the opportunity that working with Zenergi could have in protecting their budget and delivering a better service.

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.

Our principles

When you work with us, you’ll see that our values are much more than words on a website. They are the principles driving every action and decision we take as individuals and as a team.

Act with integrity

Moving towards net zero takes real commitment to change so it’s only natural you want to work with people you trust to safeguard your interests. We are unwavering in our zeal for being people you can rely on. Each of us takes personal accountability for what we say and do, correcting mistakes if they occur and always seeking ways to improve our services and solutions. We also take our commitment to integrity beyond our own organisation, working hard to foster a culture that positively impacts the communities we serve.

Inspire real action

The right words signal your net zero intent, but we think it’s action that makes them matter. We come to work to help you shape and deliver just that: real, powerful action towards a sustainable future. Our goal is to inspire and empower you with everything we do. From our practical guidance to our solutions, we want our passion for meaningful net zero progress to ignite yours.

Challenge the norm

Achieving net zero without shaking up the way things work is a tough ask. That’s why being different matters so much to us. We expect to question the status quo, to challenge old habits. It’s by embracing different thinking that we know our work will help you and our planet move towards net zero in the most effective and sustainable ways possible.

Strive for value

Our promise is built on value in all senses of the word. We value your time and your bottom line as much as we share your values about a sustainable future for your business and the planet. We strive every day to find and deliver the win-wins that help you achieve more on all these levels.

Go beyond service

Exceptional service is a baseline that we believe can only take us so far. To make the biggest impact on your net zero ambitions, we aim for partnership. We are profoundly committed to taking time to care for your needs, respect your values, support your aspirations, and closely collaborate as we guide and support you on your path to net zero.

Our clients

Your journey to net zero is why we exist. When you – and us, and all our customers – achieve more, so does the UK and the planet. All our buying power, expertise, market insight, and passion for a sustainable future is here to get you there. Faster. More economically. More sustainably.
