Our Story
A Vision 25 Years in the Making
Built upon decades of dedicated innovation and pioneering vision by a father and son team, our company was founded in May 2023. Our mission: to invent a technology that simultaneously saves customers money and contributes to environmental betterment through carbon reduction, aiming to help UK targets for net zero.
Through perseverance, we've developed a patented device that's plug and play in existing infrastructure. This not only reduces customers' gas bills by 20% and carbon emissions by the same percentage, but also ensures a quick return on investment.
Our team includes a CEO with a strong engineering background, and a newly appointed CFO with very strong accountancy and financial backgrounds with experience in startups. We have strong traction in our pilot program across the commercial and public sectors, and our future vision also includes targeting the residential sectors. As we look towards launching our business in 2027, we're identifying strong candidates to help build the team and drive future growth.
