About
Our Group.
ACS Construction Group is a UK construction, infrastructure and utilities partner specialising in complex projects across the energy and renewables, industrial, manufacturing and infrastructure sectors.
Headquartered in Cheshire, we provide national capability with strong regional delivery expertise.
With over two decades of experience, ACS has built a reputation for safe, reliable, and technically robust delivery through its integrated business divisions.
We directly manage the critical interfaces between design, earthworks, civils, construction and utilities, giving clients improved visibility and one clear point of responsibility. Our directly employed workforce and established specialist supply chain allow us to retain control while bringing in the right technical expertise where required.
Breaking boundaries. Building excellence.
Our teams work across live substations, energy facilities, manufacturing sites and COMAH-regulated environments. We bring disciplined pre-construction planning, hands-on leadership and consistent HSEQ controls to environments where there is little margin for error. Achieving the Investors in People Gold Standard and 100% in the Achilles UVDB Audit (CSR, Environmental, Health & Safety and Quality) is a testament to our shared ethos to build excellence both internally with our people and externally on all client projects.
Committed to integrity & sustainability.
We deliver every project responsibly, meeting strict legal, environmental, and health & safety standards while actively supporting industry best practice.
A people-first business.
We are a people-first business. We work hard, invest in our people and treat them well. In return, our team has a strong work ethic and does whatever it takes to deliver projects that exceed our clients’ expectations. Unlike many construction companies, we are proud to directly employ 80% of our workforce.
We are technical experts that continuously innovate to meet the most demanding and complex projects. Our hands-on approach means we don’t wait for problems to occur. Instead, we proactively spot potential issues early on, for minimum project disruption and maximum client satisfaction.
