After Mace Consult split from the main Group in a carve-out deal with Goldman Sachs, Mace Construct has shuffled its board and leadership to mark the new era
Following the departure of the Mace Consult business earlier this year, three leads are stepping down from Mace Construct.
Non-executive directors Nina Bjornstad and John Holland Kaye, have made the decision to step down from the Mace Group Board to focus on other non-executive commitments. John was appointed as chair of Sizewell C in February 2025 and chair of Cadent Gas in February 2026. Nina was appointed to the Etraveli Group Board in January 2026 and has a number of other active board roles.
Sylvia Metayer will replace Nina as chair of the Group’s People and Renumeration Committee.
The Group’s intent is to continue to align with the UK Corporate Governance Code, and it will be carrying out a review in the coming months of the governance needs of the business.
Mark Reynolds CBE, executive chairman of Mace Group, said:
“Nina and John have made a hugely valuable contribution during a pivotal period for Mace Group. Their leadership, insight and expertise have strengthened our Board and helped guide the organisation through one of the most significant transitions in our history.
“On behalf of the Group Board, I would like to thank them both for their service and support and I wish them every success in the future.”
Leadership changes
At the end of last year, Mace Construct confirmed a simplification of its operating model from five business units to three – Commercial; Public Sector, Science and Technology; and Infrastructure. The business also signalled that further phased changes would follow in 2026.
As part of this planned evolution, Paul Connolly, currently head of Construction Technical Services, will take up the role of director of Technology. Reporting to Rob Lemming, who leads the Public, Science and Technology business unit, Paul will oversee Mace Construct’s data centres division. His appointment reflects the company’s commitment to a technology-driven, engineering-led approach to project delivery in one of the sector’s fastest growing markets.
Paul’s leadership and data centre expertise will strengthen the business’ offer in this dynamic sector, ensuring it is positioned to meet increasing client demand for high performing, resilient and sustainable digital infrastructure.
Alister Grey, managing director of Technology, has recently taken the decision to pursue opportunities outside the business and will be standing down in the summer. He has worked for Mace since 2016 and was integral to the delivery of Battersea Power Station and multiple hyper-scale data centres across Europe.
To further align specialist capability with client need, Mace Construct’s Interiors business will be overseen by Gavin Seager, managing director of Specialist Services, and will deliver pure Category A and B work. The Interiors team will focus on delivering an agile, high-quality commercial fitout offer in London – strengthening integration across business units and enhancing the company’s ability to respond to market conditions with speed and precision.
Jason Millett, CEO of Mace Group, said:
“These changes reflect the next step in our long‑term plan to build a more resilient, focused and future‑ready Mace Construct. As a standalone company, we have taken the time to reset and refocus parts of our business and are sharpening our strategic direction, strengthening our leadership through internal promotions, and ensuring we continue to deliver exceptional outcomes for our clients.
“Alister has played a pivotal role in shaping and operating Mace Construct’s data centres offer, I and the wider leadership team would like to thank him for his significant contribution and commitment. We wish him every success in his future endeavours.”
