Workplace heat safety is becoming a critical concern as extreme temperatures impact employee health and productivity. Hannah Spencer’s proposal for a maximum workplace temperature law highlights an urgent issue for employers and policymakers. While legislation may provide future clarity, businesses should not wait for a legal limit before acting to protect workers.
Extreme heat can impair concentration, increase fatigue, and raise the likelihood of accidents. The law already requires employers to provide a reasonable indoor workplace temperature and assess risks. For hot weather, this includes amending work schedules, moving physically demanding tasks to cooler times, providing shaded rest areas, and relaxing dress codes.
Why Employers Must Prioritize Heat Safety Now
Good employers recognize that safeguarding staff during heatwaves is not just about compliance—it is about preventing harm and demonstrating a genuine commitment to a safe, healthy, and productive workforce. Ruth Wilkinson, head of policy at the Institution of Occupational Safety and Health, emphasizes that workers need protection now, not after new legislation passes.
Key Steps to Reduce Heat Stress at Work
- Adjust work schedules to avoid peak heat hours
- Provide free, accessible drinking water
- Install fans, air conditioning, or cooling stations
- Offer shaded rest breaks and relax dress codes
- Train staff to recognize heat-related illness symptoms
Heat Safety in Schools: A Growing Crisis
Children are struggling in overheated classrooms, with reports of pupils calling for their mothers in 40°C-plus conditions. Wet paper towels and ice pops are inadequate. Schools need systematic climate resilience plans. The Department for Education requires climate action plans, but the country needs a more coordinated approach.
Comparison of Heat Safety Measures: Workplaces vs. Schools
| Measure | Workplaces | Schools |
|---|---|---|
| Adjust schedules | Common practice | Limited flexibility |
| Cooling systems | Often available | Often lacking |
| Hydration access | Required by law | Varies by school |
| Dress code relaxation | Encouraged | Rarely implemented |
| Risk assessment | Mandatory | Not always done |
Legal Duties and Best Practices
Employers must assess workplace risks and take reasonably practicable steps to protect people. For hot weather, this includes providing shaded rest areas, free drinking water, and relaxing dress codes. The debate over a UK maximum workplace temperature is important, but action cannot wait.
FAQ
What is the maximum workplace temperature in the UK?
There is currently no legal maximum workplace temperature in the UK. However, employers must maintain a reasonable indoor temperature and assess heat risks under health and safety laws.
What can employers do to protect workers from heat stress?
Employers can adjust work schedules, provide cooling equipment, ensure access to water, offer shaded rest areas, and relax dress codes. Training staff to spot heat illness is also critical.
How can schools improve heat safety for pupils?
Schools should develop climate action plans, install blinds or shades, use fans or portable AC, allow lighter clothing, and adjust lesson times to cooler hours. Systematic investment is needed.
Protecting workers and pupils from extreme heat is a shared responsibility. By acting proactively, employers and schools can prevent harm, boost productivity, and build resilience against rising temperatures.
