Professional services firm WSP has appointed Paul Reilly as president and managing director for the company’s UK and Ireland business.

Taking over in January next year, Reilly, who has served as deputy CEO UK and Ireland, will also join WSP’s Global Leadership Team. He joined WSP in 2022 as managing director for planning and advisory.

In his new role, Reilly will drive WSP’s strategic priorities and client delivery across the UK and Ireland, reinforcing the firm’s capabilities in critical growth markets, including infrastructure, environment, water, property and energy.

The announcement coincides with the appointment of Mark Naysmith, currently president for WSP’s EMEIA region, as global chief operating officer - effective January 2025.

With more than 35 years at WSP, Naysmith will oversee global operations, driving growth, financial performance, and collaboration across WSP’s regions worldwide.

Mark Naysmith said: “After 36 years at WSP, it has been a pleasure to lead the EMEIA region, working with so many great colleagues and clients to deliver truly remarkable projects.

“Paul’s understanding of our UK and Ireland business and his commitment to client success make him an outstanding choice to take the reins.

“I am confident that under his leadership the business will continue to grow and flourish as a world-class consultancy and market leader in the UK and Ireland.”

Paul Reilly added: “I am honoured to take on this leadership role in the UK and Ireland and to continue building on the solid foundation we’ve established.

“I look forward to working with our talented teams as we deliver impactful solutions for our clients and communities and further advance our industry leadership.”
