Record Heatwaves Cause Nearly 3,000 Excess Deaths in England
In England, very hot weather in May and June caused almost 3,000 more people to die than usual.
In May, 753 extra people died, and in June, 2,124 extra people died during a rare red heat warning.
The UK Health Security Agency says July’s heatwave could add more deaths, so the total for the summer might be even higher.
They warn that 2026 could have the most heat‑related deaths ever recorded.
The Climate Change Committee says most homes could become too hot by 2050 and urges the government to set temperature limits and add air conditioning to public buildings.
May and June heatwaves in England caused 2,877 excess deaths, nearly double the 2025 summer total.
753 excess deaths in May; 2,124 in June during a rare red heat warning.
