Is there a maximum temperature to work in?
No. There is currently no guidance or UK law around a maximum temperature to work in.
However, the UK Government does say employers must stick to health and safety at work law. This includes keeping the temperature at a comfortable and “reasonable” level and providing clean and fresh air.

As extreme heat is classed as a hazard, potentially causing dehydration and heat exhaustion, all workers are entitled to an environment where risks to health and safety should be controlled.
John Rowe, of the Health and Safety Executive, said: “With a heatwave warning in place, its vital employers are aware of their responsibility to ensure their indoor workplaces are at a reasonable temperature.

Is there a minimum temperature to work in?
Legally there is no minimum temperature for when it is too cold to work. However, the UK Government guidance suggests a minimum of 16ºC – or 13ºC if employees are doing physical labour.
Have people called for a change in the law?
Unions have been calling for a maximum temperature for working conditions to protect workers.

Lynsey Mann, GMB’s health and safety officer, said: "This hot weather is great for being on a sun lounger, but if you're trying to work through it's no joke.
"Bosses need to do everything possible to keep workplaces cool and, more importantly, safe.This can be as simple as letting people wear more casual clothing and providing proper hydration.

The TUC has also called for further protections for workers. General secretary Frances O’Grady said: “We all love it when the sun comes out, but working in sweltering conditions in a baking shop or stifling office can be unbearable and dangerous.
"Bosses must make sure outdoor workers are protected with regular breaks, lots of fluids, plenty of sunscreen and the right protective clothing."
