Established in 1972 by the late Padraig Colohan, P. Colohan & Co Ltd has built a reputation as a trusted specialist contractor delivering high-quality basement, groundworks, and reinforced concrete frame solutions across London and the Home Counties.
Now led by a new generation of directors, the company continues to uphold the same core family values, professionalism, and commitment to excellence that have shaped the business for over 54 years.

We are experienced in delivering projects within constrained urban environments and tight construction programmes, working collaboratively with clients and design teams to ensure safe, efficient delivery.

We maintain a 100% CSCS-compliant workforce, supported by ongoing training and strong management systems that ensure our projects are delivered safely and professionally. Our excellent Health & Safety record reflects a company culture where people, planning, and performance matter equally.
With an annual turnover of approximately £18 million and experience delivering packages of up to £10 million, we provide the capability and resources expected from a leading specialist contractor while retaining the flexibility and responsiveness of a family-run business.

A significant proportion of our work comes from repeat business with long-standing clients, reflecting the trust we build through consistent delivery, collaboration, and reliability.
