There’s no law for maximum working temperature, or when it’s too hot to work.
In offices or similar environments, the temperature in workplaces must be reasonable.
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
Our thermal comfort checklist (PDF) can help you identify whether there may be a risk of thermal discomfort in your workplace.
Employees should talk to their employer if the workplace temperature isn’t comfortable. We have guidance on what you can do to feel more comfortable.
