Britain’s climate watchdog is pushing the government to set a national maximum workplace temperature to shield workers during heatwaves, as part of broader adaptation to a hotter, more volatile climate.

The response from unions and regulators is supportive: the Trades Union Congress backs maximum temperature laws, while the Health and Safety Executive surveys cooling measures and temperature thresholds, suggesting a comfort limit around 24°C and a stop-work threshold around 30°C (27°C for strenuous tasks).

The Climate Change Committee also backs implementing these limits to protect health and productivity, with support from major unions such as GMB and Unison.

Looking nationally, income inequality will shape how households adapt, since wealthier families can insulate or relocate more easily, while poorer households face higher exposure and fewer resources to bounce back from floods and other climate events.

Food prices and security are already under pressure from climate impacts, with annual bills rising and forecasts predicting a further surge by late 2026.

Education and housing face risk: schools may lack air conditioning by mid-century, potentially affecting over half of pupils unless cooling measures and funding are scaled up.

There could be political repercussions, as public frustration over inadequate preparation could be exploited by extreme groups, according to policy analysts.

The CCC warns of a double threat of winter floods and summer droughts, with potential river flow increases and substantial daily water shortfalls in England by the middle of the century.

Projected climate trends include hotter summers, wetter winters, and droughts, with river flows potentially rising up to 45% during very heavy rainfall periods.

Heat, floods, and drought are identified as the top three climate risks, with an expectation that up to 92% of homes may overheat by 2050 and water shortages exceeding five billion litres daily.

Building design must adapt from the start to stay cool, reducing heat risk as heatwaves become more frequent and intense.

The CCC calls for about £11 billion annually to prepare for and adapt to climate change, arguing it is essential for protecting lives and the country’s way of life.
