The Wakefield-based firm specialises in water infrastructure and will become part of United Living’s Infrastructure Services division.

Peter Duffy Ltd has been trading since 1972 and employs 135 staff.

Neil Armstrong, Chairman and CEO, United Living Group, said: “The acquisition of Peter Duffy Ltd represents another key milestone in our strategy to become a market leader in wastewater infrastructure.

“As the sector enters a period of transformational growth driven by environmental, political, and regulatory pressures, as well as long-standing underinvestment, United Living is well-positioned to be a trusted partner in delivering the sustainable, resilient water infrastructure the UK needs.

“The UK water market is preparing for a substantial upturn in investment as it enters the next regulatory period, AMP8, during this year. United Living’s continued investment in wastewater services reflects its commitment to the challenges and opportunities ahead.“

Peter Duffy, Managing Director, added: “At this critical time for the water sector, with increasing demand for reputable service providers, being part of the United Living Group presents an exciting opportunity to further develop Peter Duffy Ltd’s strong brand and service offering.

“United Living recognises the value of our long-standing history and is committed to building on this foundation to drive continued growth and excellence.”
