Permasteelisa Group has appointed Seb Fossey as its new CEO. Fossey, who most recently served as managing director of specialist engineering contractor McGee, has more than 26 years of experience working as a senior construction and engineering leader.
Before joining McGee in 2017, Fossey spent more than 15 years at Laing O’Rourke, progressing from major-project delivery roles to becoming technical leader for its United Kingdom construction business. He joined McGee as operations director and was appointed group managing director in 2019. In that role, he oversaw the company’s transformation from a demolition and groundwork subcontractor into a specialist engineering contractor offering integrated demolition, piling, civil engineering and structural services.
“We are delighted to have appointed Seb as our new Group CEO,” says Peter Bacon, Permasteelisa Group’s executive chairperson. “He will lead our team of regional CEOs in Europe, the United States, Asia Pacific and the Middle East as they continue to drive real success across their operating regions. Seb is a proven leader in our industry and will bring strategic, commercial and technical skills to his new role. His leadership, management and operational experience, coupled with a strong commitment to customer service excellence, will help further our ambitions for the business.”
Permasteelisa officials say Fossey’s experience combines technical and operational leadership, business transformation and the safe and successful delivery of complex projects. He has a strong focus on strategic leadership, building collaborative client relationships, delivery certainty and the construction industry’s response to the carbon agenda.
Fossey will join Permasteelisa on Sept. 28, 2026, at which point Bacon will relinquish his executive responsibilities while remaining chairperson. Liam Cummins will transition from his current role as deputy chairperson to a non-executive advisory director of the Group.
