Delivering a sixth consecutive year of growth, Clancy lifted turnover 13% to £379m, which helped to drive a 55% hike in pre-tax profit to £21m.

Strong profitability and a robust cash position of £34m at the April 2024 year-end enabled the family-owned contractor to invest over £11m in plant and technology to improve productivity, including rolling out a new works management system Depotnet.

Matt Cannon, chief executive, said that the 3,000 staff group’s direct labour model was assuring reliability and quality of work for clients maintaining a strong order book worth £1.5bn.

He said: “The past year has seen us expand our client base and increase the scale and breadth of our work, especially in capital projects which now account for an ever-greater portion of our revenue.

“With rising scrutiny over the challenges facing infrastructure sectors, we are fulfilling a need for stable, long-term partnership that our family-run model supports.

“Our prioritisation of direct employment ensures we bring consistency in quality and safety, together with the best available expertise.

“With a secure pipeline through 2025 and in the second half of the decade, we are well placed to invest further in the systems and skills we need: accelerating the connections and upgrades across infrastructure to support growth, increase environmental protection, and accelerate the green transition.”

Clancy has secured strategic frameworks ahead of the AMP8 water regulatory period, which begins in April 2025 with Southern Water and South West Water.

In the energy sector Scottish and Southern Energy Networks has signed up the firm to support grid expansion and decarbonisation in the ED2 control period, as well as ongoing capital project delivery for UK Power Networks in London and the South East.
