The Chorley-based firm that employs over 800 staff posted revenue of £227m for the year to 31 December 2025, up from £216m, while pre-tax profit jumped 29% to £17m.

A focus on tighter cost control and delivery efficiencies lifted operating margin to 6.9% from 5.8% last time.

Growth was fuelled by stronger client relationships across water and power, with new wins including expanded work with Scottish Power Energy Networks and a framework deal with Welsh Water.

This helped offset a slower-than-expected AMP8 ramp-up and the loss of a Yorkshire Water contract.

Cashflow remained strong, supporting continued investment in assets, technology and workforce, while the acquisition of Jacopa Ireland expanded Avove’s footprint into Northern Ireland Water.

The contractor said it is now well-positioned for a step change in activity as AMP8 gathers pace, highlighting early involvement in Northumbrian Water’s Living Water Enterprise programme and a growing pipeline of strategic projects.

Bosses flagged a strong order book heading into 2026, targeting further revenue growth, improved profitability and sustained cash generation as long-term frameworks accelerate.
