No legal maximum temperature for UK workplaces
As the UK bakes in a heatwave with temperatures predicted to reach 38°C, legal expert John Kushnick has outlined workers' rights concerning unsafe workplace temperatures. Currently, the Workplace (Health, Safety and Welfare) Regulations 1992 obliges employers to maintain a 'reasonable' temperature, but no upper limit is set. The Labour government is considering introducing a threshold, but Kushnick argues it may be too late.
Kushnick, Legal Director at National Accident Helpline, stated: "The fact is that without a legal maximum, many people will feel pressured to continue working when it is not safe to do so."
Workers feel pressured to cut safety corners
National Accident Helpline's data reveals that 41% of workers feel pressured to cut corners on safety to get the job done faster, and 56% say health and safety in their workplace is more about box-ticking than genuine care. Kushnick added: "Put simply, without enforced policies, employees will continue feeling uncared for and forced to work when it is unsafe to do so."
Employers' responsibilities during hot weather
Employers are expected to do whatever is 'reasonably practicable' to protect workers' wellbeing, including providing a safe environment free from heat-related illness risks. They must consider those with existing health conditions and provide reasonable adjustments. Kushnick noted: "If the temperature within the workplace rises to over 28°C, then it may have become too hot to safely work."
Dangers for outdoor and transport workers
Construction sites and transport networks are most at risk. On the London Underground, temperatures can reach 40°C, impairing concentration and making machinery operation hazardous. Measures like large fans in tube stations have little impact. Even office workers in ageing buildings without air conditioning face risks of heatstroke and dehydration.
What to do during a heatwave
Workers should take regular breaks, stay hydrated, and report concerns. While there is no legal maximum temperature, employees are entitled to stop working if they feel conditions are unsafe. If an employer neglects responsibilities and someone is injured, compensation may be claimed.
