The UK Health Security Agency (UKHSA) estimates that heatwaves in England in May and June this year were associated with 2,877 deaths. Multiple outlets report that the figure is almost double the total number recorded for the previous summer period, with the comparison made against the 2025 heatwave months (reported as June to August last year). The BBC and Sky News describe the agency’s assessment as preliminary, based on available data. A breakdown reported by Vancouver Sun indicates 753 “extra” deaths in May and 2,124 in June, when there was a rare red heat warning. The Guardian also reports that the estimated heat-associated deaths for May and June are close to that doubled level compared with summer 2025. Overall, the reporting converges on the same central estimate and the same year-to-year comparison, while noting that the figures come from UKHSA modelling or assessment rather than final counts.
