United Infrastructure is a leading provider of essential infrastructure services across the UK, focused on creating a connected and sustainable future. The company has a rich history, evolving from Fastflow, a water utility maintenance specialist, through strategic acquisitions and growth. In 2019, Fastflow merged with United Living to form United Living Group, significantly enhancing its geographical coverage and service offering.
A pivotal moment was the 2021 acquisition of Great British Communications, now United Living Connected, bolstering its capabilities in the telecommunications sector. The company rebranded to United Infrastructure in 2025 to better reflect its expanded scope and capabilities. Today, United Infrastructure operates across five key sectors: Water, Energy, Power, Telecoms, and Social Infrastructure.
The company delivers critical infrastructure for major network owners and operators, focusing on resilient and flexible solutions that support sustainability goals and community needs. This includes everything from water and wastewater management to energy and power distribution networks, and connecting people through advanced telecommunications infrastructure. They also focus on regenerating living spaces and revitalising neighbourhoods through their Social Infrastructure division.
With a strong commitment to safety, ESG principles, and continuous improvement, United Infrastructure employs over 2,700 engineers, managers, and skilled operatives. They pride themselves on fostering an inclusive workplace, investing in their people through extensive training and development, and maintaining high standards through accreditations like Investors in People Gold. The company actively collaborates with its supply chain partners, emphasizing shared values, reliability, and a drive for innovation in quality, sustainability, and value.
United Infrastructure is using digital innovation, including live risk dashboards, AI-powered quality assurance, drone technology, and connected works management, to create safer, smarter, and more productive construction sites.
