Excess deaths caused by heatwaves in England ‘almost double’ so far this year

The UK Health Security Agency (UKHSA) has reported that an estimated 2,877 people died in England during heatwaves throughout May and June. This figure represents a significant increase, nearly doubling the number of heat-related fatalities recorded during the same period in 2025.

Current data suggests that England is on track to record its highest number of heat-related deaths in a single summer. These findings highlight a sharp rise in mortality linked to extreme temperatures, prompting ongoing monitoring of the impact of heatwaves on public health across the region.
