The UK Health Security Agency (UKHSA) estimates that heatwaves in England in May and June lead to 2,877 “heat-associated” deaths, with the total considered close to a record year for heat-related fatalities. Multiple outlets report that the figure is almost double the number recorded for the whole of summer 2025, which was 1,504 heat-related deaths. Coverage also notes that this year’s early-summer totals are based on preliminary data and are presented as an indication of the scale of the public health impact rather than a final count.
One outlet that cites UKHSA figures further breaks down the deaths by month, reporting 753 extra deaths in May and 2,124 in June, when a rare red heat warning was issued. Other reporting describes the May–June death figure as nearly double the entire 2025 summer total, using data newly revealed by the agency. Overall, sources converge on the same estimated deaths linked to the May and June heatwaves and on the comparison with last year’s summer totals.
