The Skipton-based firm, part of the Mott MacDonald Group, credited its direct-delivery model and tight operational controls for another year of steady margin growth, with profit margins improving from 3.5% to 3.7%.
Turnover jumped 31% to £510.2m in 2024, fuelled by a late surge in workload on major water frameworks for Yorkshire Water and Welsh Water. The increase came as clients released larger volumes of work ahead of the AMP7 finish line.
Revenue from its main joint venture, Mott MacDonald Bentley, surged to £503m, while JBA Bentley contributed a further £20m delivering projects in the environmental sector.
To support the increased workload and prepare for further demand under AMP8, JN Bentley ramped up investment in plant and machinery, with spending more than doubling to £26m. The company added over 200 new items to its fleet during the year.

The forward order book stood at £552m at the end of March 2025. While directors expect revenue growth in 2025 to be more modest, they see strong opportunities ahead as AMP8 frameworks gain pace following a staggered rollout.
Cash at bank rose to £32m with net assets up 34% to £39m, reflecting a year of solid trading and reinvestment.
