Professional, Scientific and Technical Activities was the most affected sector in Ireland during 2025, with 499 insolvencies, accounting for 22% of all business failures over the year. This reflects sustained pressure on professional services firms, particularly smaller operators exposed to rising costs and delayed client payments.
Construction followed closely, with 243 insolvencies, representing 11% of total cases. Despite relatively stable year-on-year growth, the sector remained highly vulnerable, reflecting continued challenges around input costs, financing, and project delays.
Wholesale and Retail also recorded elevated insolvency levels, with 209 firms entering insolvency, while Administrative and Support Service Activities saw a notable 64.5% year-on-year increase, reaching 232 insolvencies.
Combined, these sectors accounted for over 40% of all insolvencies in 2025, highlighting the concentration of financial distress in labour-intensive and margin-sensitive industries.
