CIBSE members’ outstanding contributions and dedication to the Institution and the wider building services industry were recognised with medals at the 2025 President’s Awards Dinner. Taking place each October, the annual celebration brought together members and guests to honour individuals who have made an exceptional impact on the profession and their communities.
Held at Claridge’s Hotel in London, the Dinner highlighted the essential role that CIBSE members play in supporting the Institution’s mission to promote building services engineering, invest in education and research, and support the global community of building environment professionals.
In total, four Gold Medals, four Silver Medals and eleven Bronze Medals were presented to recognise exceptional service and commitment. The medals celebrate long and loyal service to CIBSE and the sector, and the recipients’ dedication to raising the profile of the profession.
Vince Arnold, 2025/26 CIBSE President, said: “The President’s Awards Dinner gives us the opportunity to celebrate those who go above and beyond to inspire, to innovate, and to lead. It is a moment to recognise the achievements of our peers, and to highlight the outstanding contributions that continue to drive building services forward. As a profession, we are uniquely placed to address the urgent challenges of our time – climate resilience, energy efficiency and the transition to net zero. And I am proud to say that CIBSE is not only part of the conversation, but we are also helping to shape it.”
