Voltempo, the British clean-tech company pioneering ultra-fast EV charging for heavy goods vehicles, today announced the appointment of Simon Smith as its new Chief Executive Officer (CEO). His appointment marks a major phase in the growth of Voltempo and the rollout of the UK’s largest depot-based eHGV infrastructure network under the eFREIGHT 2030 project.
The appointment underscores the company’s commitment to accelerating commercial growth and expanding its impact in the UK and international clean mobility sectors. It follows the start of series production of its advanced Megawatt Charging System (MCS), the Voltempo HyperCharger, a significant milestone in the UK’s transition to zero emission road freight.

Voltempo founder Michael Boxwell, the driving force behind the company’s pioneering approach, takes on a new role as Corporate Development Officer. He will continue to shape Voltempo’s future through product innovation, strategic partnerships, and engagement with government stakeholders and transport ecosystem partners.
Simon brings extensive experience in EV charging, energy strategy, and high-growth leadership, having guided teams through rapid transformation in both private equity-backed and PLC environments. Most recently, as an Executive Committee member at InstaVolt, the UK’s largest rapid EV charging network, he played a key role in one of the industry’s most successful infrastructure rollouts and led the company’s commercial scale-up. An established thought leader in the EV sector, Simon champions reforms that improve regulation, accelerate adoption and enhance customer experience.
“Voltempo is entering an exciting and dynamic new phase,” said Simon Smith. “I’m looking forward to driving the next stage of growth and ensuring our technology is deployed in a way that meets the day-to-day realities of commercial vehicle operations. Our goal is clear: create robust, financeable infrastructure that improves efficiency for fleets and accelerates the transition to zero-emission HGVs across the UK.”
Joining Simon and Michael on Voltempo’s leadership team is John Fox, appointed as Chief Operating Officer. A Chartered Engineer with over 20 years’ experience across mobility, energy and innovation, John was previously Chief Technology Officer at Indra Renewable Technologies, where he led the company’s award-winning Technology team. John has also held senior engineering roles at Rolls-Royce and GE Aviation, bringing extensive technical expertise and a strong track record of turning complex, advanced engineering concepts into scalable, real-world solutions.
Paul Jordan, Chief Commercial Officer, and Benjamin Didier, Chief Financial Officer, continue to drive Voltempo’s mission to transform the delivery of zero emission transport and energy infrastructure at scale.
Michael Boxwell, Corporate Development Officer, commented: “Simon’s appointment marks a decisive moment for Voltempo. As we accelerate the rollout of the UK’s largest eHGV charging network through eFREIGHT 2030, his leadership and commercial experience will be instrumental in delivering our clean-tech solutions on a national and international scale. Together, with John, Paul and Ben, we have a leadership team in place ready to deliver the step change the industry has been waiting for.”
