Coffey Construction Limited:

Founded in 1974, the Coffey Group (Coffey Construction Ltd, Coffey Construction (I) Ltd and Coffey Water Ltd) is a family owned engineering-led Civil Engineering, Environmental and Building contracting group of companies.  Coffey Group was established in 1974 by brothers Paddy and Tom Coffey and has since grown to build a reputation for consistent quality delivery of projects throughout Ireland and the UK in the civil engineering, environmental and building sectors. The group headquarters remains in Athenry County Galway, as is the main depot for the extensive Coffey Group plant division.

After initial success in the Irish market, Coffey Group expanded into the UK market in 1988, originally as Coffey Brothers Ltd. A re-brand and name change occurred in 1995 and the group now trades in the UK as Coffey Construction Limited.

In 2000, having identified the water industry as a key growth area, Coffey Group sought to expand its service offering by forming a joint venture with the operation specialists Treatment Systems Limited. This joint venture, TSSL, successfully leveraged the expertise and resources of both parties to provide a one-stop-shop for design, build and operate (DBO) services for water and wastewater treatment plants. In 2013, Coffey Group acquired 100% ownership of TSSL, which was then re-branded Coffey Water Ltd. In 2015, Paddy and Tom Coffey retired, handing over the ownership and management of Coffey Group to the next generation of the Coffey family who continues to develop the business based on a strategy of sustainable growth and always remaining true to Coffey Group’s values. Coffey’s operate in every major construction sector and we undertake work throughout the UK and Ireland.  We are passionate about quality and efficiency, and this passion drives our belief in delivering projects with a directly-employed workforce.
