Soaring temperatures and potential workplace hazards are raising concerns about how prepared employers are for extreme heat.
With temperatures possibly exceeding 38C, and at least matching the June record of 35.6C set in 1976, extreme heat warnings and health alerts have been issued.
The UK Health Security Agency (UKHSA) warned people to expect significant impacts across health and social care services along with a rise in deaths, particularly among those aged 65 and over or with health conditions.
As part of the Health and Safety at Work Act 1974, employers have a duty to provide a safe working environment, which includes keeping employees protected from weather-related hazards, including excessive heat.
John Johnston, head of e-commerce at Workwear Express, said that under health and safety laws, employers must take reasonable steps to protect employees during periods of extreme weather, especially when working outdoors.
Key requirements include providing PPE designed for high temperatures, conducting thorough risk assessments, and ensuring all workers are trained to identify symptoms of heat exhaustion and other heat-related conditions.
Employers should also offer sheltered areas for breaks to help staff cool down and recover from prolonged sun exposure.
In high temperatures, the risk of workplace accidents rises due to sunburn, dehydration, and heatstroke, which is why employers are also required to provide first aid resources and ensure a trained first aider is present on site.
Despite the hazardous conditions, there is currently no legal maximum workplace temperature in the UK.
This means employees cannot leave work solely because of high temperatures.
However, you have the right to refuse to work if you think that your working conditions are unsafe or there is a serious risk to your health and safety - which comes under the Employment Rights Act 1966.
Trade union members are also encouraged to contact their unions for advice and support if they feel unsafe at work during extreme heat.
