Mott MacDonald has reported a year of solid performance for 2025 with a gross revenue of £2.48 billion and a pre-tax profit of £107.8 million. During the year the business secured positions on AMP8 frameworks with 10 water companies in the UK.

Gross revenue was 1.4% down on 2024 (£2.51 billion). Operating profit of £89.7 million was 10.9% down from 2024 ( £100.7 million) with the operating margin at 3.6% (2024- 4.0%). The profit before tax margin at 4.3% was also down from 2024 (4.9%).

However, the contracting business, a UK business principally operating in the UK water market, has seen good revenue growth in the current year, up 6.3%.

The report states:

“With the next Asset Maintenance Programme (AMP) cycle about to start, it is well positioned for continuing revenue growth, given its successful track record with the previous AMP7 cycle work and the framework wins it has secured for AMP8…..

“The contracting business benefitted from increased profit and improved margins in the year, bene3fitting from strong markets as the current AMP7 cycle drew towards a close and as aMP8 offered some opportunity in the early stages of the next traing cycle.”

The figures reflect the business’ ability to respond with agility amidst a backdrop of economic uncertainty, technological innovation and shifting geopolitical dynamics. Throughout the year, significant progress was made on key initiatives to evolve the business, while continuing to build its resilience and position for future growth.

In a milestone moment for Mott MacDonald and its 20,000 people, the business announced it was enhancing its employee-ownership model in 2025, enabling all employees to have a stake in the business and voice in shaping its future.

The business also further accelerated its digital ambition, investing in partnerships with key technology providers including Microsoft, while launching its own generative AI assistant “Every Mott MacDonald Answer” – EMMA – to democratise knowledge and best practices for its employees.

Across 2025, Mott MacDonald continued to act as a trusted partner on some of the world’s most complex infrastructure projects spanning transport, energy, water, defence and security, and buildings infrastructure. This includes achieving major project milestones on Changi Airport Terminal 5 in Singapore, for National Grid Electricity Transmission, the Gowanus Canal in Brooklyn New York and the reopening of the Sydney Fish Market earlier this year.

The business secured positions on AMP8 frameworks with 10 water companies in the UK as well as on East-West Rail. It was also appointed to advise Matarat Holding on airport development across the Kingdom of Saudi Arabia, is supporting the modernisation programme for Toronto Pearson Airport in Canada and is working with the Australian Department of Defence on its Base Services Transformation Program.

James Harris, executive chair of Mott MacDonald, said:

“Enhancing our employee ownership model in 2025 was a real milestone moment for the business. It means that having delivered a solid performance, our employees benefit from the success we achieve together. Our people are at the heart of our business and this extends to our approach to technology and AI which we further accelerated across the year. We are well placed for the future and to continue delivering long-lasting value for clients and the communities they serve.”

Current business environment - looking ahead in 2026

Commenting on the current business environment in the business and financial section of the annual report, Mott Macdonald says:

“Geopolitical disruption and economic uncertainty continued to impact our business environment.

The threat of a global recession receded during 2024 but in many economies low business confidence, negative market sentiment and economic uncertainty continued to depress market activity in the first half of 2025, before a slight uptick in volumes in the second half.

“We do not expect much change in those market pressures in 2026. Organic growth is expected to be low across our markets, continued to be depressed by pressures on private sector investment and public sector infrastructure budgets, against a backdrop of economic uncertainty and geopolitical disruptors impacting business confidence and depressing the level of infrastructure projects.”
