Employee Ownership Shapes How We Deliver
We are a Lancashire-based business, delivering quality construction projects across education, industrial, healthcare, defence, commercial, leisure, heritage and public sectors nationwide.
Founded in 1961, we’ve built our reputation on operational excellence, prioritising partner-led delivery and long-term relationships, embedding social value into every project and a “getting it right first time” approach.
Today, we combine the strength and stability of an established contractor with a people-first culture, designed to create a positive impact, where every employee has a meaningful stake in long-term success.
Through carefully selected frameworks, repeat partnerships and direct award projects, we continue to deliver sustainable growth while creating lasting value for our clients, communities and supply chain partners.
Built on heritage. Powered by people.
Built on more than 65 years of expertise, we’re proud that the same commitment to hard work, quality delivery and long-term relationships continues to define the employee-owned business today.
The people within Conlon are the reason we’re chosen to deliver projects nationwide through trusted frameworks, including North West Construction Hub and the Department for Education Construction Framework – long–term partnerships and public and private sector procurement.
Our joined-up approach and commitment to collaboration prove that true partnerships are the key to delivering the best projects.

CREATING LASTING VALUE BEYOND CONSTRUCTION
Social value is built into everything we do. In 2025, we achieved an average Considerate Constructors Scheme Score of 44.6 out of 50, reflecting our genuine commitment to creating positive social, economic and environmental outcomes alongside every project.
This isn’t just a badge of honour. We live and breathe it. That means creating local opportunities, facilitating hands-on apprenticeships, working towards net zero, creating stronger supply chain partnerships and championing responsible construction – on every project, every day.
