Revenue, including joint ventures, jumped nearly 20% to £2.9bn in 2025 after the French-owned group brought together Eurovia, Ringway, Taylor Woodrow, VINCI Building, VINCI Facilities and newly-acquired FM Conway under the VINCI Construction Holding UK structure.

A strong improvement in profitability saw group-wide operating margin climb to £3.5% from 1.7% previously, helped by the FM business returning to the black and stronger margins at Taylor Woodrow.

FM Conway made the biggest contribution following its acquisition at the end of January, adding £569m of revenue and nearly £39m of operating profit.

Among the established businesses, highways maintenance specialist Ringway again delivered the strongest operating profit, while Taylor Woodrow increased its contribution to £19m from £17m in the prior year.

VINCI said Eurovia also turned in a solid performance, although profitability at VINCI Building and VINCI Facilities remained constrained by legacy project risks, limiting returns from both businesses despite combined revenue of more than £1.1bn.

Chief executive Scott Wardrop said: “These results are a credit to the six core operating business managing directors, their respective senior management teams in each of our principal operating businesses and all our teams in our business units and projects.

“We have all endured significant change in our careers, but this intense period is unprecedented.

“However, we are optimistic, and we have three-year plans for each business and each business unit, and plan to deliver +4.0% in 2026.

“We will keep evolving through optimisation, innovation and transformation and continue to develop into a strong and resilient dynamic UK infrastructure group.”

The UK group saw headcount rise over a third to nearly 9,000 in the year, driven by the incorporation of FM Conway.
