Heatwave Forces UK Schools to Close, Costing Millions of Teaching Hours

Heatwave Triggers Widespread School Disruptions
An eight-day heatwave in June pushed indoor temperatures in some classrooms above 40 °C (104 °F). A red health alert was issued across large parts of the United Kingdom, prompting hospitals to cancel operations, workplaces to shorten hours, and public warnings against travel. The extreme heat forced hundreds of schools in England and Wales to shut completely or finish the day early, leaving pupils and staff coping with heat stress, nausea and headaches.
Scale of the Disruption
The DeSmog analysis, based on reported closures and official absence data, estimates that at least 760,000 schoolchildren missed lessons during the heatwave. This translated into more than 15 million teaching hours lost, with over 1,700 schools closing fully or curtailing the day. Where schools stayed open, absenteeism rose sharply as parents kept children home. One parent reported taking a five-year-old out of school after the child returned with severe heat rashes.
Official Responses and Funding Plans
The department announced investment to make schools more climate-resilient, including a £710 million renewal and retrofit programme and almost £20 billion earmarked to rebuild more than 750 schools.
Expert and Union Concerns
Jenny Cooper, a teacher and National Education Union safety representative, described staff and pupils fainting and a colleague being taken to A&E. Education researchers warned that missed school days could lower exam results and harm mental health, especially for students who rely on schools for nutrition and social support. Charlotte O’Regan of the Sutton Trust warned that the closures risk widening the attainment gap for pupils in deprived areas, noting that state school leaders already face difficult funding decisions.
