P. Colohan & Co. Ltd.
P. Colohan & Co. Ltd was founded in 1972 by the late Padraig Colohan. Over more than five decades, we have become a trusted specialist contractor, delivering high-quality basements, groundworks and reinforced concrete frames across London and the Home Counties.
Today the business is led by a new generation of directors who carry forward the family values, professionalism and commitment to quality it was built on.
Whether it's a complex basement or a full reinforced concrete frame package, we provide practical, reliable solutions and support our clients from early engagement right through to completion.
From its beginnings as a groundworks contractor, the business has grown into a multi-disciplined contractor offering:
- Bulk excavation
- Basements
- Underpinning
- Groundworks
- Drainage and services
- Reinforced concrete frame packages
- External works
Delivering in challenging environments
We have a strong track record on constrained urban sites and tight construction programmes. We work closely with clients and design teams from the outset so that every project is delivered safely and efficiently.
Safety, quality and reliability
These three values sit at the heart of everything we do. Our workforce is 100% CSCS-compliant, backed by ongoing training and robust management systems. Our excellent health and safety record reflects a culture where people, planning and performance matter equally.
Capability with flexibility
With an annual turnover of around £18 million and experience delivering packages worth up to £10 million, we have the capability and resources you'd expect from a leading specialist contractor. As a family-run business, we're also flexible and quick to respond.

Built on long-standing relationships
Much of our work comes from repeat clients, a sign of the trust we build through consistent delivery, collaboration and reliability.
