UK Urged to Set Maximum Workplace Temperatures as Climate Heat Risks Intensify

The United Kingdom should introduce a legal maximum temperature for workplaces to protect employees as heatwaves become more frequent and severe due to climate change, according to the government’s official climate advisers.

The Climate Change Committee (CCC) has warned that rising temperatures, alongside more extreme droughts and flooding, are beginning to threaten everyday life in the UK, from outdoor events such as sports matches and music festivals to the safety and productivity of workers in offices, factories, and public buildings.

The committee has called for urgent action, including widespread investment in cooling systems such as air conditioning in schools, hospitals, and other critical infrastructure. It argues that adapting buildings and public services to hotter conditions should now be treated as a national priority rather than a secondary concern.

Although the CCC did not propose a specific legal temperature limit for UK workplaces, it pointed to international examples such as Spain, where indoor working conditions are regulated with maximum temperatures set at 27°C for sedentary work and 25°C for more physically demanding tasks.

The warnings come amid growing concern that the UK is increasingly unprepared for the realities of a warming climate. The committee stressed that the country was “built for a climate that no longer exists today,” highlighting the mismatch between existing infrastructure and current environmental conditions.

Baroness Brown, who chairs the CCC’s Adaptation Committee, criticised what she described as the “woeful” response of successive UK governments to climate risks. She argued that despite clear evidence of escalating climate impacts, governments have consistently failed to prioritise adaptation measures needed to protect people and infrastructure.

She said that climate change is already reshaping the British way of life, warning that “it’s not rocket science” to understand the necessary solutions, but that political will has been lacking in implementing them effectively.

The UK government responded by saying it would carefully consider the committee’s recommendations and provide a formal response in due course. Officials also pointed to existing investments in flood defence systems as part of broader efforts to prepare for climate-related risks.

However, the CCC’s latest assessment adds to growing pressure on policymakers to move beyond long-term climate targets and focus more urgently on adapting to immediate and unavoidable changes. Experts say that without stronger action, heatwaves and other extreme weather events are likely to place increasing strain on public health, infrastructure, and economic activity across the country.

As climate patterns continue to shift, the debate over workplace safety standards, building design, and national preparedness is expected to intensify, with calls for concrete legal protections for workers likely to gain further momentum in the months ahead.
