What is the context?
The Climate Change Committee (CCC) is the UK adviser to the government on climate change. Their report, A well-adapted UK was published on 20 May 2026. It details three risks to the UK – overheating, flooding and drought. The report sets out a recommendation to set maximum working temperatures.
Since the publication of the report in May, we have seen the impacts of overheating in educational settings in a landscape of multiple weather records broken and alerts in place, examples include:
- 2026 becoming the first on record in the UK to reach 35 degrees in three consecutive months – May, June and July.
- The warmest June on record in England – 37.7 degrees
- The UK Health Security Agency (in partnership with the Met office) issuing many health alerts over the summer, including a rare, red alert in June indicating that the weather could bring risk to life.
All of this followed 2025, being the hottest year on record.
The impact of this is members reporting teaching and working in 33-degree heat in some classrooms/workspaces.
ASCL position: Schools and colleges are increasingly experiencing periods of extreme heat which make it difficult to maintain comfortable and productive learning and working environments. Rising temperatures can have a significant impact on the wellbeing, concentration and performance of staff and their pupils/students.
We call on the government to set a maximum workplace temperature and to provide the resources to ensure that all education settings can maintain reasonable working conditions.
Why are we saying it?
It is essential that working conditions are reasonable. We know heatwaves will intensify in future years and it is necessary that government invest in the education estate to allow reasonable working conditions.
