UK workers could be bracing themselves for a serious heatwave as temperatures are set to soar well beyond seasonal expectations, with the Met Office forecasting highs of up to 29°C this week.
Beginning the week with warm spells of 24°C to 25°C, temperatures are expected to rise steadily before peaking on Wednesday or Thursday. According to meteorologists, there is a small but notable chance that some areas could see 29°C, more than 10 degrees above the seasonal average of 12°C in the North and 16°C in the South for late April.
These unusually warm conditions may be welcome to some, but for thousands of British employees – particularly those working outdoors or in poorly ventilated environments – the unseasonal heat could pose serious health and safety risks.
Legal responsibilities and safe working practices
Under the Health and Safety at Work Act 1974, employers have a legal obligation to provide a working environment that is safe and free from health risks, including those brought on by extreme weather conditions. As the mercury rises, so too does the importance of following health and safety protocols to help beat the heat.
John Johnston, head of e-commerce at Workwear Express, reminds employers and employees alike of the critical measures that should be taken when temperatures climb beyond the norm. Johnston underscores the importance of:
- Risk assessments
Employers must carry out comprehensive risk assessments to evaluate the impact of hot weather on their workers. This includes reviewing the physical environment, the nature of tasks being performed, and the risk of heat-related illnesses such as sunstroke and dehydration.
- Training and awareness
All workers should receive adequate training to ensure they understand how to operate safely in hot conditions. Training should include recognising the symptoms of heat exhaustion, the importance of hydration, and when to seek medical attention.
- Implementation of safe processes
Procedures must be adapted to suit high-temperature environments. For example, scheduling heavy labour during cooler hours, encouraging frequent breaks, and adjusting dress codes where appropriate are sensible approaches to working conditions and employee wellbeing to protect worker health.
- Sheltered rest areas
Providing shaded or air-conditioned break areas is not a luxury, but a necessity. A cool, sheltered space enables workers to regulate their body temperature, especially after prolonged exposure to direct sunlight.
- First aid availability
Given the increased risk of sunburn, fainting, or heat stroke, a well-stocked first aid kit must be readily available, alongside trained first aid personnel who can respond to any incidents quickly and appropriately.
What are your rights as an employee in hot weather?
While there is no legal maximum temperature for workplaces in the UK, the Employment Rights Act 1996 allows employees to refuse to work if they believe their health and safety are at serious risk.
However, refusing work due to heat alone is not typically acceptable unless the working environment has become genuinely dangerous. It is recommended that employees raise concerns directly with their employer in the first instance, ideally in writing, highlighting specific hazards and asking for reasonable adjustments.
In cases where employers fail to take necessary steps to mitigate risk, workers have the right to escalate the issue by communicating effectively at work with a health and safety representative or external workplace safety advisory body.
A proactive approach for British workplaces
With climate patterns becoming increasingly unpredictable, now is the time for UK businesses to futureproof their health and safety policies. Heatwaves, once rare in spring, may become more frequent due to broader environmental changes.
Employers must be aware that a proactive response is not only a legal responsibility but also a crucial aspect of employee well-being, morale and productivity. By fostering a culture of health awareness and preparedness, businesses not only stay compliant but demonstrate their commitment to their workforce.
The Workers Union Says…
“For workers, understanding your rights and being vigilant about your own safety during hot spells is equally vital. Communication, documentation, and education are the most effective tools in ensuring a safe working environment—regardless of the weather.”
