Family-owned construction group Collen has reported a rise in revenue and profitability for the year ended 31 March, which is said reflected consistent and steady growth across its operations in Ireland, the UK and mainland Europe.
Collen said its group revenue for the year jumped by 79% to €1.18 billion, up from €660m for the same time last year.
The company said the strong year-on-year growth mirrors the significant surge in demand from its longstanding clients in the technology sector across Europe and the UK.
Its profit after tax for the period rose to €42m from €18.2m in 2024 and the group said it has no bank debt and significant net assets retained within this growing business.
Collen has projects in Ireland, UK, Germany, Sweden, Finland, Denmark and other northern European markets and has a team of over 450 direct staff and another 5,000 people within its supply chain.
Founded in Ireland in 1810, the company said it delivers projects across all major sectors and while maintaining a strong focus on its domestic market, it now derives the majority of its turnover from projects throughout Europe.
"Our 2025 performance reflects the breadth of our portfolio and the work delivered by our committed teams across all of the regions in which we operate," Leslie FitzPatrick, Collon's chief financial officer said.
"Revenue and profit growth were achieved alongside continued investment in the business, our people and a focus on financial discipline. We expect demand in the data and technology sectors to remain strong, with additional opportunities emerging in critical infrastructure, energy, residential and healthcare. Our order book provides a solid platform for the year ahead," the CFO added.
The eighth-generation business is positioning itself for its next phase of growth and has strengthened its capabilities with the appointment of Mark McGreevy as chief executive, from January 2026.
Looking ahead, Collen said it anticipates a stable outlook for the Irish construction sector and welcomed the recent publication of the Government's Accelerating Infrastructure Report, noting the clarity it provides for national investment priorities to help drive the efficient delivery of infrastructure across Ireland.
The company confirmed that it intends to support the delivery of planned critical infrastructure as outlined.
