An increasing number of people are dying from excessive heat in the UK. More than 4,500 people died in England in 2022 due to high temperatures, which was the largest figure on record. Between 1988 and 2022, almost 52,000 deaths associated with the hottest days were recorded in England, with a third of them occurring since 2016, data from the Office for National Statistics shows. During the same 35-year period analysed, more than 2,000 people died in Wales due to the warm temperatures.
