Latest results for the year to December 31 2024 show that the smaller consulting operation is the main profit driver making £77.7m from £44.6m last time on increased turnover of £686.6m from £619.4m.

Group Executive Chairman Mark Reynolds said: “One construction project impacted our overall performance. However, the project has since been closed out and we have made a number of decisions to improve the consistency with which our Construct business will measure risk and operate going forward.

“We know we are good at what we do – delivering for our clients and leading the industry – and the lessons we learnt in 2024 have intensified our focus on the resilience and efficacy of our business.

“We have made fundamental changes to how we operate, manage risks and decide who we work with.”

Chief Executive Jason Millett was bullish about future prospects for the construction division.

He said: “I want to take Construct’s strong foundations and transform it into a more resilient, productive business, even more effective at identifying and mitigating risk, with more predictability on our projects and better use of data and digital practices.”
