The UK's independent climate change advisers have issued a stark warning, stating that successive governments have demonstrably failed to adequately prepare the nation for the escalating threat of extreme heat. In a new report, the climate watchdog has strongly recommended the introduction of a legal maximum working temperature to safeguard employees across various sectors.
Currently, UK law mandates a minimum working temperature of 16°C in most workplaces, or 13°C if the work involves rigorous physical effort. However, there is no corresponding legal upper limit, leaving employers without clear guidelines and employees potentially vulnerable during periods of intense heat. The advisory body argues that this regulatory gap is increasingly untenable given the scientific consensus on climate change and the observed rise in average temperatures and frequency of heatwaves in the UK.
The report underscores that the implications of extreme heat extend far beyond individual discomfort. It poses significant risks to public health, productivity, and critical national infrastructure. Hospitals and care homes face immense pressure, transport networks can buckle under the strain, and outdoor workers, in particular, are exposed to serious health hazards including heatstroke and dehydration. The advisers emphasised that proactive measures are now essential to mitigate these growing risks.
Responding to the report, a spokesperson for the Department for Energy Security and Net Zero acknowledged the challenges posed by a changing climate and stated that the government is committed to ensuring the UK is resilient to future weather extremes. They highlighted ongoing work to adapt infrastructure and public services. However, specific commitments regarding new legislation on maximum working temperatures were not immediately made.
Labour's Shadow Secretary of State for Climate Change and Net Zero welcomed the report's findings, reiterating the party's long-standing call for improved worker protections and a more robust national strategy for climate adaptation. They indicated that a Labour government would seriously consider implementing such a legal limit, stressing the importance of protecting workers' health and maintaining productivity in a warming world. The Liberal Democrats also voiced support for the principle of better protecting workers from extreme heat, urging the government to act swiftly on the recommendations.
The recommendations come at a time when the UK has experienced several record-breaking heatwaves in recent years, leading to significant disruption and an increase in heat-related illnesses and deaths. The climate watchdog's intervention aims to prompt a more comprehensive and legally binding approach to managing the impacts of rising temperatures on daily life and the economy.
