Temperature in the workplace: working safely in hot conditions

In offices or similar environments, the temperature in workplaces must be reasonable.

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.

Read about what you can do to feel more comfortable.

HSE's temperature website has practical guidance on what you can do to manage the risks, including:

• factors that can lead to heat stress, and how to reduce the risk of it occurring
• managing outdoor working environments.

HSE also has the answers to some frequently asked questions about temperature in the workplace.
