More than 40,000 extra people died on England’s hottest days between 1988 and 2025 compared with what would be expected in normal temperatures, according to new ONS data.

The strain has been visible across the health system: A&E departments saw their busiest period on record, with almost 2.5 million attendances a month in May, June and July, with record-breaking heat cited as a key factor. Nurses reported collapsing on shift amid what their union called “inhumane and impossible” conditions.
