Is there a maximum classroom temperature?


Maximum classroom temperatures can be a hot topic for discussion during the summer months. GOV.UK explains that during working hours the temperature in all indoor workplaces must be reasonable.

It notes that there’s no guidance for a maximum temperature limit. 

Similarly, it’s the same for minimum classroom temperatures which we have written about here.

Employers must stick to health and safety at work law, including:

  • Keeping the temperature at a comfortable level
  • Providing clean and fresh air

During working hours the temperature in all indoor workplaces must be reasonable. In this article, we look at the topic of temperatures in classrooms and what you can do if you would like to raise a concern with your school.

No maximum classroom temperature set by the DfE

The School Premises (England) Regulations 2012 (which applies to maintained schools) do not specify maximum classroom temperatures for any parts of a school. Similarly, the Education (Independent School Standards) Regulations 2014 (which applies to academies) does not specify a maximum classroom temperature.

Essentially, the Department for Education (DfE) does not specify maximum temperatures for classrooms in England.

However, your school has a duty of care for your health and safety so you should be able to discuss with your line manager if you are concerned about the temperature in your classroom.

Employers have a duty of care for their staff

The Health and Safety at Work etc. Act 1974 requires employers to ensure the health, safety and welfare of their staff and others. 

ACAS also explains that employers have a duty of care to their employees, which means that they should take all steps which are reasonably possible to ensure their health, safety and wellbeing.

It should also be noted the Health and Safety Executive says that although the law does not state a minimum or maximum temperature, the temperature in workrooms should normally be at least:

  • 16 degrees
  • 13 degrees if much of the work involves rigorous physical effort

How to raise a concern with your school

If you are concerned about your classroom being too warm you will be able to raise the issue with your line manager or headteacher.

You will be able to do this informally in the first instance and then potentially raise a grievance with your school if the issue persists and is having a significant impact on your health and safety.

We have published another article which outlines the process of how to raise a grievance with your school. You can also contact us for further advice and support on this issue.
