Britain's climate advisors have called for the government to establish maximum working temperature thresholds, warning that the country remains dangerously unprepared for extreme heat events. The Climate Change Committee, the UK's independent statutory advisor, issued the recommendation as part of a broader assessment of the nation's heat resilience.

The watchdog pointed to repeated failures by successive administrations to implement adequate protections against rising temperatures. Unlike many European nations, the UK currently lacks mandatory workplace temperature limits during heatwaves, leaving workers vulnerable to heat stress and illness.

The Committee's findings come as Europe experiences more frequent and intense heat events linked to climate change. France, Germany, and other nations have enforced workplace temperature rules for years, often requiring employers to provide cooling measures or allow workers to leave when conditions exceed safe thresholds. Spain and Portugal have implemented specific temperature limits, typically ranging from 28 to 34 degrees Celsius depending on work type.

Britain's lack of preparedness extends beyond workplace standards. The advisors highlighted gaps in emergency response protocols, cooling center infrastructure, and public health messaging around heat-related dangers. The NHS has reported increasing admissions during summer months, particularly among elderly and vulnerable populations, yet the health system operates without comprehensive heat-action plans across most regions.

The government has previously resisted introducing temperature limits, citing concerns about business costs and enforceability. However, the Climate Change Committee argues that inaction poses greater economic risks through lost productivity, healthcare expenses, and worker compensation claims.

The timing coincides with mounting evidence that the UK's infrastructure, from roads to rail networks, struggles during heat events. Recent summers have seen track buckling, school closures, and warnings to elderly residents to stay indoors. Climate projections suggest temperatures exceeding 40 degrees Celsius will become routine within decades if emissions continue unchecked.

The Committee's recommendation signals pressure on policymakers to treat heat as a public health priority rather than a seasonal inconvenience.
