England records nearly 2,900 excess deaths during recent heatwaves as GPs advised to consider closing surgeries in extreme heat

An estimated 2,877 excess deaths have been recorded in England following this summer’s heatwaves, prompting renewed warnings about the growing impact of extreme temperatures on public health and NHS services. The figures, published by the UK Health Security Agency (UKHSA), relate to two periods of exceptionally hot weather between late May and late June and bring this year’s toll close to the record set during the 2022 heatwaves, with August still to come.

Alongside the latest mortality data, updated guidance for general practice advises surgeries to take action when indoor temperatures become unsafe. The Royal College of General Practitioners (RCGP) says practices should aim to keep indoor temperatures below 26°C for comfort and should consider relocating services or temporarily closing if indoor temperatures reach 30°C, where excessive heat could affect staff wellbeing, concentration and patient safety.

Heat can significantly increase the risk of illness and death, particularly among older people, babies, pregnant women and those living with cardiovascular, respiratory or other long-term health conditions. The World Health Organization describes heat stress as the leading cause of weather-related deaths globally and warns that rising temperatures are increasing the frequency and severity of heat-related illness.

Health leaders say the figures highlight the need for healthcare buildings and services to become more resilient to extreme weather. Researchers from the London School of Hygiene & Tropical Medicine, Imperial College London and the Met Office have previously estimated that more than 2,700 heat-related deaths occurred across England and Wales during the May and June heatwaves, with climate change contributing substantially to the severity of the events.

As further periods of hot weather remain possible this summer, NHS organisations and primary care providers are being encouraged to review heatwave plans, monitor indoor temperatures and take steps to protect both patients and staff during extreme conditions.
