Builders, bakers and cheeseburger-makers: the UK workers struggling in extreme heat

Workers throughout the United Kingdom are experiencing significant strain as temperatures exceed 35C in major cities, prompting renewed discussions about workplace safety standards during heatwaves. Those employed outside air-conditioned environments—including chefs, construction workers, bakers, paramedics, bus drivers, and teachers—report severe physical challenges that impact their ability to perform their jobs safely.

In the hospitality sector, kitchen staff at establishments such as the Plimsoll pub in north London have implemented creative adaptations to reduce heat exposure, including menu modifications and cooling techniques. However, workers in physically demanding roles face greater obstacles. Construction workers highlight the particular vulnerability of older employees in the industry, with one 65-year-old noting the risk of dehydration, heat stroke, and potentially fatal outcomes. Bakers report that ovens and provers compound outdoor temperature increases in already-warm workspaces, creating hazardous conditions in some facilities with inadequate ventilation.

Essential workers including paramedics and ambulance staff face constraints that prevent them from simply ceasing work during extreme conditions. They report sweating profusely during routine tasks and point to the inflexibility of uniform requirements that remain constant regardless of temperature. Bus drivers have voiced frustration about inadequate air conditioning systems in vehicle cabs, where temperatures can exceed 40C, and some have taken strike action to protest working conditions.

A campaign advocating for maximum workplace temperature thresholds has gained momentum among trade unions and worker representatives. Several European countries have established such standards: Spain implements 27C for sedentary work and 25C for light physical work, while Belgium uses a tiered system based on activity level. The Trades Union Congress and various unions are calling for UK employers to take action when temperatures exceed 24C and for work stoppages at 30C, or 27C for strenuous positions. Supporters argue that if such regulations function in Spain, where summer heat exceeds typical UK levels, they would be feasible for implementation in Britain.
