A strategic approach to sustainability, energy and waste
Sustainable Advantage partners with Private Equity funds and businesses across the UK, France, and wider Europe.
Since 2010, our multidisciplinary team has been helping business leaders shape and deliver sustainability strategies while managing their utilities contracts.
Our approach is holistic and hands-on: we co-develop strategies with clients – from defining Net Zero pathways and engaging stakeholders across the value chain, to embedding sustainability within governance structures – and support operational implementation across energy, waste, and infrastructure.
Our trading desk secures energy contracts and renewals efficiently by leveraging market dynamics and tracking consumption to uncover opportunities for energy reduction.
Through our self-service portal, clients benefit from real-time alerts and intuitive energy dashboards. We also manage and expedite the delivery of utility infrastructure connections and metering, accelerating the opening of new sites and often reducing associated costs.
Our waste division identifies sustainable disposal solutions for all waste streams, from food to clinical waste, with a focus on cost reduction and increasing recycling rates. We offer full account management, a dedicated UK helpdesk, a compliance portal, and comprehensive reporting to ensure visibility and control.
Many of our clients operate across multiple sites, spanning sectors such as education and training, healthcare and social services, pharmaceuticals, agribusiness, hospitality, construction, manufacturing, real estate, business services, technology, Private Equity, and infrastructure funds.
Our history: why was Sustainable Advantage created?
Founded in 2010, Sustainable Advantage was born from a vision to help organisations leverage sustainability as a strategic asset. From the outset, our goal was to embed sustainability across every level of our clients’ operations: driving higher customer and employee retention, lower operating costs, and meaningful competitive differentiation.
Starting with a single office in Hersham, we expanded to Brighton as our team and client base grew. Over the years, we developed deep partnerships with a diverse range of clients across sectors – from hospitality and manufacturing to healthcare, retail, and beyond. In 2018, our growth was recognised when we were named one of the UK’s fastest-growing companies in the Sunday Times Fast Track 100, a major milestone in our journey.
As ESG and sustainability demand surged, we evolved our offering into a comprehensive engagement program. Today, we support clients from ESG strategy development through to implementation. Our delivery expertise in energy and waste enables us to provide a fully integrated, cross-functional service.
Our continued growth led to the opening of our London office and, in 2025, our Paris office, broadening our European presence and enhancing support for our local and international client base. Today, Sustainable Advantage is a team of around 100 professionals, operating from offices in Hersham, Brighton, London, and Paris. We have worked with over 700 clients across 24 countries and more than 15,000 sites.
Over the years, we have developed a strong presence in the private equity sector, supporting ESG due diligence and portfolio-wide ESG transformation, preparing businesses for successful, ESG-aligned exits.
Our contributions in this space have been recognised with multiple award nominations, including ESG Value Creation Advisory Firm of the Year to Private Equity, ESG Consultancy of the Year, and ESG Due Diligence Provider of the Year, a testament to the value we deliver to our clients.
