There were an estimated 2,877 heat-related deaths during the May and June heatwaves in the UK, almost double the figure reported last year, according to the UK Health Security Agency (UKHSA).
In a preliminary assessment, it said an estimated 753 deaths were associated with the 24-27 May heatwave and a further 2,124 with the one from 21-28 June.
Both spells broke Met Office UK monthly temperature records, with 31.5C (88.7F) recorded at Kew Gardens on 26 May and 38.0C recorded at Lingwood, Norfolk on 26 June.
"Based on the interim data, it is likely that 2026 could see the highest number of heat-associated deaths on record," the UKHSA said. Definitive figures are expected in early 2027.
The previous record was set in 2022, when 2,985 deaths were recorded.
