Weather is the “go to” conversation for the English!! And hasn’t there been some great content this week!!
The UK is in the grips of a heatwave with schools allowing casual uniform and offices baking as the mercury continues to climb. Temperatures are predicted to reach 35 degrees in some parts of the country this weekend and into next week, leaving many employees starting to perspire into their ear pods, but how hot does it need to be before workers should be sent home by their employers?
And is there a maximum temperature before sweating school pupils are sent home in the heat?
Heatwave workplace guidance

If your office doesn’t have air conditioning, and your employees are starting to wilt at their desks what are the guidelines?
The official guidance reads: “In offices or similar environments, the temperature in workplaces must be reasonable. There’s no law for maximum working temperatures, or when it’s too hot to work.”
It adds that employers have a responsibility for “keeping the temperature at a comfortable level, sometimes known as thermal comfort” and for “providing clean and fresh air”.
Employers have a duty of care to look after their employees, so if several workers complain about the heat, they are legally required to carry out a risk assessment and introduce measures that keep working conditions manageable.
Earlier this week the TUC urged employers to make sure their staff are protected from the sun and heat after the UK Health Security Agency (UKHSA) issued a health alert.
“Working in hot weather can lead to dehydration, muscle cramps, rashes, fainting, and – in the most extreme cases – loss of consciousness,” the TUC says.
While you might currently be baking in the boardroom, the idea that you can demand your boss send you home from work when it reaches a certain temperature is actually a myth in the UK.
Much to the dismay of a lot of people, there are no laws that specify a maximum temperature when an office or workplace becomes too hot to continue working.
How can you keep cool in the office?
While legally there’s not much you can do in terms of getting sent home in the heat, the HSE does issue advice as to what you can do to “improve thermal comfort in your

Ministers are drawing up plans for Britain’s first national heatwave emergency response amid predictions the mercury could pass 40C this weekend, according to reports. A Cobra meeting was held at Downing Street on Monday after the Met Office issued an amber weather warning for large swathes of the UK. The Government could declare a national emergency if temperatures continue to climb, the Telegraph reports. A national emergency is called when hot weather is so extreme that “illness and death may occur among the fit and healthy”, according to the UK Health Security Agency (UKHSA).
How about this for a great idea? As each summer seems to be getting hotter, you can look to adding a couple of ‘Sun Days’ to your employees leave allowance. It’s along the same lines as your Birthday leave or the summer equivalent of a duvet day.
