Cheltenham-based battery manufacturer, Mark Millar, has once again been recognized for his exceptional leadership and entrepreneurial skills. On Wednesday, November 26th, 2025, Millar was named Family Business Entrepreneur of the Year at the prestigious Great British Entrepreneur Awards (GBEA).
This marks Millar’s second consecutive win, solidifying his position as one of the UK’s most influential leaders in the clean-tech and manufacturing industries. The award ceremony, held at the Grosvenor House Hotel in London, is the largest celebration of entrepreneurship in the UK and honors individuals and businesses that drive innovation and contribute to the country’s economy.
Puredrive Energy, based in Gloucestershire, was originally a family-run start-up with only four employees. Today, it is the fastest-growing home battery manufacturer in the UK, with over 400 active installers across the UK and Europe. The company is best known for its high-performance Duracell Energy home storage systems, designed in the UK.
In 2022, Puredrive secured a brand licence to manufacture, market, and distribute Duracell-branded home energy storage products. This partnership has allowed the company to scale rapidly while supporting thousands of UK homeowners in storing low-cost, renewable energy to reduce both bills and carbon emissions. Puredrive exclusively supplies Duracell Energy storage products, emphasizing its commitment to quality and reliability.
The GBEA judges noted that Puredrive’s identity as a true family business sets it apart in the energy sector. Millar runs the company alongside his two sons, Oliver and Daniel, who head the marketing and sales departments, respectively. Their shared vision has fostered a culture of resilience, innovation, and agility, which has proven essential during a challenging year filled with economic, political, and environmental pressures.
Despite these challenges, Puredrive has continued to flourish, increasing its market share and achieving significant revenue growth. The company’s success can be attributed to its ability to adapt quickly to shifting demand and global logistics uncertainty, particularly important for a business operating in the UK, Europe, and South Africa.
This latest accolade adds to Puredrive’s impressive list of achievements in 2025, including being named a finalist at the Gloucestershire Business Awards and winning two UK Contact Centre Forum awards for excellence in customer service.
Upon receiving the award, Mark Millar, CEO of Puredrive Energy, said: “This recognition means a lot to me and our family team. We’ve always believed that staying focused, adaptable, and constantly striving for improvement leads to success, even in challenging times. What truly matters is that we’re helping more homeowners take control of their energy and become more self-sufficient. This award serves as a reminder that we’re on the right path, and we’re excited to continue growing, improving, and supporting those seeking a cleaner, more reliable way to power their homes.”
Looking towards the future, Puredrive is preparing for a milestone year, with plans to increase their business by 50%. They are set to launch a new generation of energy storage products and expand their operations in the Benelux region, solidifying their position as a leader in the European energy storage market.
