Employee-owned Mott MacDonald generated £2.52bn revenue in 2024, up 6% on 2023’s £2.37bn.
Pre-tax profit was up 9% at £123.3m (2023: £112.9m).
Directors said that the performance highlighted the resilience of the business in the face of economic and political uncertainties across its operations in Europe, North America, Asia, Australasia and the Middle East. Organic revenue growth of 7.6% was indicative of a strong performance, they said.
Mott MacDonald experienced growth in its UK consultancy business, with key appointments to support National Grid in the design of two high-voltage links to increase renewable energy connectivity and continuing its work with Holtec Britain and Hyundai Engineering & Construction to explore the delivery of small modular reactor technology. Alongside its UK contracting business there was also good growth and opportunity in the water sector around the new AMP8 regulatory period.

In North America, Mott MacDonald built on successes in transit, tunnels and underground infrastructure and energy, where it was appointed to provide programme and project management services for the Santa Clara Valley Transportation Authority. Work is ongoing in storm flood relief as it continues to support the upgrade of Philadelphia’s historic sewer system.
In Australia and New Zealand, Mott MacDonald strengthened its offering with the acquisition of specialist consultancies, Merz and Neo Engineering respectively. It was also selected by Queensland Hydro to provide engineering services for the upper and lower dams at the proposed energy hydro storage system at Lake Borumba.
In Saudi Arabia, Mott MacDonald was appointed as city infrastructure engineer for the first phase of The Line, which forms part of Neom, the region taking shape in the northwest of the kingdom.
Executive chair James Harris said: “The last 12 months mark another year of good performance for the business, as our revenues reached £2.5bn for the first time. Though economic and political uncertainties persist across many of our regions, our recently enhanced employee ownership model and our long-term strategy ensure we are well positioned to continue growing, and to keep on delivering the right impact for our clients and the communities they serve.”
