Maximum temperature’ limits for workplaces proposed by Labour – The Irish Times
Legislation to establish a maximum workplace temperature in Ireland is currently under development by the Labour Party, according to Senator Neasa Cosgrove. While Irish law mandates minimum temperatures—17.5 degrees for sedentary office work and 16 degrees for other sedentary roles—no current statute restricts how hot an indoor environment can become. Senator Cosgrove argues that rising temperatures necessitate new protections for workers in sectors such as construction, retail, and hospitality.
Why is Ireland considering a maximum temperature law?
The push for new legislation follows recent heatwaves where temperatures climbed to 30 degrees. According to Senator Cosgrove, these conditions pose health risks for employees in poorly ventilated environments. She contends that current regulations focus exclusively on cold-weather protections, leaving staff vulnerable during summer months. The proposed bill aims to bring Ireland into alignment with European norms, where maximum heat levels are already a standard feature of occupational safety.

How does Ireland compare to other European nations?
European countries have adopted varying standards to manage thermal comfort, providing a blueprint for potential Irish legislation. Germany maintains a maximum workplace temperature of 26 degrees, while Spain sets its limit at 27 degrees, according to Senator Cosgrove. By contrast, Irish law currently only enforces a floor for temperature, specifically requiring 17.5 degrees for office-based sedentary work after the first hour of operation, as stated in existing safety codes.
Many European trade unions are currently lobbying for a unified EU directive on maximum workplace temperatures to ensure consistent safety standards across all member states.
What would the new regulations look like?
Senator Cosgrove suggests the proposed limits could range between 25 and 30 degrees. However, she emphasized that the legislation would not be one-size-fits-all. Employers would likely be required to implement mitigation strategies rather than simply closing sites. These measures include improved ventilation, mandatory water breaks, and the use of fans. The requirements would be tiered based on the nature of the work, distinguishing between sedentary office roles and physically demanding environments like kitchens or construction sites.

Common Questions About Workplace Heat
- Is there a legal maximum temperature for work in Ireland right now? No. While there are legal minimums, there is currently no legislation capping how high the temperature can go.
- Which sectors would be most impacted by this law? Retail, hospitality, catering, and construction are identified by Senator Cosgrove as the industries most likely to require adjustments.
- When will this legislation be introduced? Senator Cosgrove intends to present the proposals in the Seanad following the summer recess.
If you are an employer, you can proactively improve thermal comfort by conducting a ventilation audit before new regulations are finalized. Proper airflow is often more effective than cooling systems in industrial settings.
