Is it too hot to work? 

There is some great advice on the HSE website on keeping the temperature at a comfortable level, sometimes known as thermal comfort providing clean and fresh air.

There’s no law for maximum working temperature, or when it’s too hot to work. 

Employers must stick to health and safety at work law, including:
  • keeping the temperature at a comfortable level, sometimes known as thermal comfort
  • providing clean and fresh air
