UK Unions Demand Legal Maximum Indoor Temperature of 30°C

Labor unions across the UK intensified calls on August 14 and 15 for a legal maximum indoor working temperature of 30°C. The demands follow a series of intense heatwaves that have pushed temperatures to record levels, causing significant disruption to infrastructure and posing serious risks to public health and safety.
Pressure Mounts for Indoor Workplace Safety Regulations
Teachers' unions and healthcare representatives are leading the push for new legislation, noting that there is currently no legal maximum temperature for indoor work in the UK. The National Education Union emphasized the need for investment in heat resilience, while the Climate Change Committee has recommended that indoor temperatures should ideally be maintained between 16°C and 25°C by 2050.
The Royal College of Nursing described conditions in many hospitals as inhumane, reporting that ward temperatures have exceeded 30°C, leading to instances of staff collapsing. In Nottingham, university hospitals declared a critical incident earlier this summer due to the heat, reporting a surge in admissions for dehydration, hyperthermia, and delirium among older patients.
With extreme heat putting staff at risk across hospitals and schools, reviewing your workplace risk assessments has never been more urgent.

Transport and Health Services Struggle Under Extreme Conditions
The transport sector has seen significant labor action linked to rising temperatures. More than 1,500 Arriva bus drivers in London launched strikes in mid-August, reporting that temperatures inside driver cabs have reached as high as 44°C. The Unite union warned that such extreme conditions could lead to serious accidents due to driver heatstroke.
Emergency services are also facing severe strain. The UNISON union reported that ambulance crews have been operating in temperatures exceeding 35°C without functioning air conditioning and in uniforms ill-suited for the heat. The union is calling for mandatory summer safety plans to protect frontline workers who are currently handling back-to-back calls during 12-hour shifts.
Infrastructure Risks and Growing Public Health Toll
The heatwave has caused significant damage to the national rail network, leading to two derailments in mid-August. An incident near Lewes resulted in two severe injuries, while another derailment occurred near Wickford. The TSSA union stated that these events demonstrate the rail network is unprepared for the climate crisis and requested urgent discussions with Prime Minister Andy Burnham regarding infrastructure investment.
Network Rail officials confirmed that investigations into the derailments will consider extreme heat as a primary factor. While the organization has allocated £1.6 billion for climate resilience in the current funding period, officials suggested that more funding will be necessary for the next five-year cycle to prevent further track failures.

The human cost of the 2026 summer has been substantial. Data indicates that approximately 2,877 heat-associated deaths occurred in England and Wales during May and June alone.
June 2026 was recorded as the hottest June on record with a peak of 37.7°C, while Kew Gardens in London reached 38.1°C on August 13. Environmental groups have noted that nearly 75% of England is currently experiencing drought conditions, with fire services reporting their busiest periods in decades due to over 1,000 wildfires and other incidents.
