England experiences 35% surge in ambulance calls during June 2026 heatwave

England’s ambulance services recorded some of their busiest days ever during the June 2026 heatwave, with call volumes surging by up to 35 percent compared with the same period last year, according to data analysed by Carbon Brief. The spike was most pronounced in the southeast, where temperatures topped 38 °C for three consecutive days, prompting a flood of emergency calls for heat‑related illnesses, dehydration and cardiac events. The NHS reported that more than 12,000 additional ambulance deployments were logged across the country in the ten‑day heat spell, straining crews already stretched by staffing shortages.

The unprecedented demand reflects a growing pattern of extreme heat in the UK, which climate scientists say is now five times more likely than a generation ago. June 2026 marked the hottest month on record for England, breaking the previous high set in 2022. Health officials warn that rising temperatures exacerbate existing pressures on the National Health Service, from increased hospital admissions to longer response times for other emergencies. The heatwave also exposed gaps in public awareness, as many vulnerable people failed to take basic precautions such as staying hydrated or seeking shade.

Health Minister Wes Streeting pledged a rapid review of emergency response plans, urging local authorities to boost community cooling centres and improve public messaging ahead of the predicted 2027 heatwave season. The NHS is set to pilot a “heat‑health taskforce” in the most affected regions, aiming to coordinate ambulance dispatches, hospital capacity and preventive outreach. Experts say the trend will likely continue, making it essential for policymakers to invest in climate‑resilient health infrastructure and for citizens to adapt their daily habits as extreme heat becomes the new normal.
