Mace Executive Board

Jason Millett

CEO for Consultancy

Jason is the Chief Executive Officer for Consultancy, responsible for leading our 3,000 strong team of consultants globally. With a track record of best-in-class delivery, and a commitment to bringing an exceptional service to clients, Jason is leading teams on some of the most significant projects and programmes around the world.

What roles have you had over your career at Mace?

I am responsible for Consultancy at Mace, where I lead the company’s growth activities and around 3,000 consultants across the UK and Europe, Middle East, The Americas, Asia Pacific and Sub Saharan Africa. This ranges from global infrastructure to property and real estate. I am also the Group Board Sponsor for Health, Safety and Wellbeing, a member of the Responsible Business Board, a Trustee of the Mace Foundation and the company’s Healthcare Trust.

Prior to this role I led Mace’s Global Projects and Infrastructure business, which included strategic oversight across utilities, energy and transport sectors. I joined Mace back in 2008 and immediately became part of CLM, the private sector partner in charge of delivering the 2012 Olympic and Paralympic Games in London on behalf of the Olympic Delivery Authority (ODA).

What is your proudest moment at Mace?

I feel privileged to have been part of a number of successful projects at Mace, where I have seen real tangible benefits being brought to communities and people across the world. 

One of the greatest moments in my career has to be London 2012, where I was charged with ensuring all the contractors involved in this massive programme – one of the largest in Europe – delivered consistently and effectively to the highest standards of safety and quality. It was a huge feat and I feel proud to have been part of the Games. 

After delivering the Games, I’ve remained closely involved with the delivery of legacy commitments. Mace is working closely with the London Legacy Development Corporation (LLDC) to transform the Olympic Park into a thriving space for the local community. The appointment with the LLDC means that Mace will be one of the only companies to have worked on the Olympics and its legacy from the very beginning through to the very end.

I felt that same sense of pride when Mace teams delivered the Pan American and Parapan Games venues in 2019. Not only was it a chance to deliver another transformative and exciting sporting infrastructure project, but we also felt proud to be working in partnership with the UK Government to do so, in the first relationship of its kind. The next global event of its kind is the Dubai Expo where Mace alongside partner Jacobs is delivering infrastructure as PMC.

With these projects, it goes beyond delivery to knowing that our efforts will go on to have huge long-term benefits for the people who have worked on those projects and the local communities whose lives are positively impacted.

How have you seen the company develop during your time here?

Mace has gone from strength to strength over the past few years. It’s fantastic to have been leading Consultancy’s growth and profitability, forging new partnerships, developing new teams, and establish such a strong presence internationally.

In 2013, I took on the challenge to develop our infrastructure business. I led its growth, which doubled year on year, and expansion into sectors, such as transport, including rail, highways, aviation, and also energy and utilities. I am proud of the fantastic relationships we have built with our clients and successful track-record in these sectors. This is exemplified through our roles on Heathrow, PMC for Schiphol Airport, the Commercial Delivery Partner to the UK’s Defence Equipment and Support organisation, Doha Airport and Construction Partner to HS2 for their flagship Euston station.

I have also led on our growth and diversification into new markets internationally, including in East Africa following an acquisition in 2017 of a leading quantity survey practice, YMR. MaceYMR is now working of some of the most high profile development and social infrastructure projects in the region and we are excited at the opportunities across Africa both for our teams and communities we serve. In addition in 2017 we expanded our geographical footprint into the Americas through LATAM, and further afield in countries such as Vietnam, India and Australia, we continue to be involved in some iconic projects shaping skylines.

In Consultancy we are always trying to find better ways to deliver for our clients, looking for ways to improve infrastructure delivery, drive growth and development. We have real breadth and depth of capability across the business; along with our drive and spirit, it’s what makes us unique and what helps to set us apart.

I believe that at the heart of what we do is giving back to communities and future generations – it’s so important.

Where would you like to see Mace in five years’ time?

I’d like to see Mace be firmly established as the UK’s leading international consultancy delivering projects and programmes globally, and recognised for being the most diverse and sustainable business, while continuing to help with vital infrastructure needs around the world.
