UK on track for record heat-related deaths this year, UKHSA estimates

The UK is heading towards the highest number of heat-related deaths since records began this year, according to estimates from the UK Health Safety Agency (UKHSA).

A preliminary assessment stated that there were an estimated 2,877 heat-related deaths during the May and June heat waves; This figure is almost double the figure for the whole of last year.

An estimated 753 deaths were associated with the heat wave from May 24 to 27, and 2,124 deaths were associated with the heat wave from June 21 to 28. Final figures are expected in early 2027.

Both spells broke Met Office UK monthly temperature records, with 35.1C (95.2F) recorded at Kew Gardens on 26 May and 38.0C recorded in Lingwood, Norfolk, on 26 June.

The current record for heat-related deaths was set in 2022, when 2,985 deaths were recorded.

The author of the report from UKHSA, Dr. “Although the figures are provisional, they show that if we experience further spells of hot weather this summer we could see the highest number of heat-related deaths on record,” said Ross Thompson.

Thompson added: “These figures highlight the serious danger that very hot weather can pose to people’s health.

“This is especially true for those who are more vulnerable, including older adults and people with underlying medical conditions.”

“As the climate warms, we can expect periods of hot weather to become longer, more frequent and more severe,” he said, adding that it is vital that the country is prepared to cope with higher temperatures.

Earlier this week parts of the UK were sweltered by another heatwave that peaked on Wednesday, with temperatures reaching 35.2C in Writtle, Essex.

Cooler conditions and some rain are expected for some on Thursday and into the weekend, but this is unlikely to be the case in the driest areas.
