The business we know today was created in 2019 following the merger of Fastflow Group, an established gas, water and energy engineering business, and property specialist United Living to form United Living Group, a major player in the construction and infrastructure sectors.

Since 2019, United Living Group expanded into new markets and strengthened its project delivery capabilities. In 2021, it completed the acquisition of Great British Communications, (renamed to United Living Connected), a specialist telecommunications provider which played a vital role in connecting people through fixed-line and mobile telecom infrastructure.

In 2024, United Living Group expanded its capabilities in the water sector with the acquisition of AFECO, a leading provider of water solutions. This strategic move complemented the Group’s existing activities and expanded its service offering. During the same year, United Living also acquired GTEC, a leading training specialist, to help bridge the skills gap and expand workforce capability and capacity. The Group then acquired PiLON, a leading property services business operating in the social housing sector, further enhancing the group’s service offering and adding value to customers and the communities we serve.

In 2025, the Group continued its growth trajectory by strengthening its presence in the power sector. It acquired Jones, a prominent power distribution and street lighting contractor, along with a majority stake in Glenelly Infrastructure Solutions, a power distribution specialist. Together, these acquisitions significantly enhanced United Living’s service capabilities, geographic reach, and customer base within the UK’s power sector.

To reinforce its leadership in the water sector, United Living also acquired Peter Duffy Ltd, a civil engineering contractor specialising in water infrastructure. Following on the earlier acquisition of AFECO, the addition of Peter Duffy Ltd represented another key step in the Group’s strategy to expand in the UK’s water sector, particularly in the high-demand area of wastewater services.

In September 2025, United Living was renamed to United Infrastructure, to better describe the company it had evolved into. United Infrastructure reflects the scale, complexity, and importance of our work delivering critical infrastructure across the UK.
