Irish construction firms are entering winter with strong order books and a cashflow warning attached. A new report from Atradius found that 92% of Irish building materials firms fear late payments this winter, even though they expect profit to rise 42% and revenue 41%. PBC Today reported the findings on 20 October 2026, noting that new dwelling completions rose 32.9% year on year in the first quarter. For leaders across the built environment, the message is clear: growth on paper only creates value when the cash arrives on time.

The wider picture explains why the warning deserves attention. The CSO shows overall building and construction output down 4.1% year on year in the first quarter, so demand is uneven across the sector, yet residential construction activity rose 12.3% in the second quarter. Three dimensions carry particular weight for building and architecture practices: credit vetting, cash reserves, and cost pressure. Each sits within management control, which makes this a solvable problem rather than a structural threat.

Credit vetting is the first gap. Only 24% of firms proactively assess customer creditworthiness before trading, 27% regularly monitor payment behaviour, and 25% respond reactively once problems arise. Sheena Bohan, head of commercial at Atradius Ireland, warned that strong sales do not automatically mean strong cashflow. In residential development, where payment runs from developer to contractor to supplier, one late payer can stall every link behind it. Practices that check client standing before accepting an appointment protect both fee income and delivery teams.

Preparation is thinner than confidence. Only 22% of firms have built cash reserves and 33% have reviewed cashflow forecasts, yet 36% historically face winter cashflow challenges. Costs add pressure: wholesale construction product prices rose 3.1% year on year in June, and wholesale electricity prices rose 42.2%. CIF chief executive Andrew Brownlee noted that 79% of firms reported higher raw material costs in Q4 2025. With planning to completion now averaging four years, according to the Central Bank, long payment chains make reserves especially valuable.

Three actions are specific and attainable. First, vet every new client's credit standing before signing, and review payment behaviour quarterly. Second, align architectural design fee stages with payment milestones, so a delay on one stage cannot compound across a project. Third, stress-test reserves against invoices arriving 60 days late, and assess trade credit insurance, which only 10% of firms hold. Boards that adopt these measures before January will enter 2027 with cash secured and clients better understood.

The Atradius findings are a prompt, not a prophecy. With new orders rising for a third consecutive month in AIB's September survey and residential activity up in the second quarter, Irish building and architecture firms have the demand they need. Firms that pair that demand with disciplined credit control will convert growth into cash and protect margins through winter and beyond.
