Mace drives defence sector growth with appointment of new lead

Mace, the global company of consultancy and construction experts, has appointed Graham Seage as its Head of Defence and National Security, placing him in charge of a team of 430 people working across Europe.

In this role, Graham will spearhead Mace's work on critical defence programmes, underscoring the firm’s continued growth in the sector. This will involve building on longstanding client relationships with the Ministry of Defence, Defence Infrastructure Organisation, Defence Equipment & Support and Babcock, as well as developing the new relationships and securing new commissions across Europe.  

Graham brings over three decades of industry expertise to his new position, marked by a proven track record of managing multi-disciplinary teams across the utilities, rail, highways, aviation, marine, defence and sports sectors.

Graham joined Mace in 2007 and has carried out several notable roles in his time at the business, including heading up Mace’s utilities division and serving as commercial director on major programmes such as the London 2012 Olympics and HS2.  

Graham Seage, Head of Defence and National Security at Mace, said:

“As I step into the role of Head of Defence and National Security, I couldn’t be clearer on the importance of Mace’s role in supporting critical defence programmes at a time where the sector is a key priority.

“With a steadfast commitment to excellence, I look forward to collaborating with our talented teams to take forward the business into its next chapter of growth, ensuring soldiers and personnel receive the necessary equipment and support they deserve.”

Jason Millett, Group Deputy CEO and CEO for Consult at Mace, said:

“Our defence and national security business has grown considerably over the past five years, with our programme and project delivery teams involved in some of the largest critical defence programmes across Europe. Graham’s appointment is a clear signal of intent of our ongoing commitment to the sector and the clients we are, and will be, delivering for.

“Graham’s expertise will play a pivotal role in driving the expansion of our service lines to unlock best practice and better cater for the evolving needs of the sector. His guidance will ensure that our growth is both substantial and sustainable, paving the way for a more secure future for defence.”

Graham Seage has been serving as the interim Head of Defence and National Security since February 2024 after taking over from David Martin who is now Managing Director of Mace’s Asia Pacific global hub. Graham will report to Andy Beard who has recently been appointed as Managing Director for Infrastructure in Europe.
