About
About ACS.
ACS is a leading UK construction services group, delivering high-quality, end-to-end solutions across the energy and infrastructure sectors. Headquartered in Cheshire, with established operations across Yorkshire and the Midlands, 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.
Our structure enables us to manage projects from concept through to completion, ensuring consistency, control, and value at every stage. We primarily deliver projects as Principal Contractor, taking full accountability for programme, safety and commercial performance, whilst also supporting Tier 1 energy contractors on complex and specialist packages.
Breaking boundaries. Building excellence.
Our purpose is to break boundaries and build excellence. We do things differently. We are driven to raise the bar in construction industry standards. We are incredibly determined, honest and reliable technical experts. We know our craft and we never stop pushing forward, innovating and progressing.
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.
