Protecting Workers from Extreme Heat: PCS Backs TUC Call for Legal Limits

The TUC recently concluded its week of action on workplace temperatures, revealing alarming findings about heat exposure in UK workplaces. Hundreds of health and safety reps carried out inspections, with nearly 60% reporting indoor temperatures above 27°C, which is well beyond comfortable working conditions. Many workplaces lacked proper ventilation, relying instead on desk fans or open windows, while outdoor workers, especially in construction and delivery, faced prolonged exposure to extreme heat.

Workers reported symptoms such as headaches, dizziness, and fatigue, underlining the urgent need for reform. The TUC is calling for a legal maximum indoor temperature of 30°C (27°C for strenuous work), and for employers to take action when temperatures exceed 24°C. PCS supports these TUC demands.

As climate change intensifies, heatwaves are becoming more frequent and severe. The TUC’s campaign highlights the need for climate-resilient workplaces, which is already government policy. UK civil service departments are mandated to carry out climate adaptation risk assessments and develop climate adaptation plans.

Adapting the workplace can be as simple as improving ventilation, providing shaded rest areas, fitting blinds to windows, allowing flexible working hours, and relaxing dress codes.

PCS is clear that everyone deserves to be safe and comfortable at work, whatever the weather.
