UK Heatwave Triggers Record Ambulance Demand as Emergency Services Warn of Growing Summer Pressure
A record-breaking heatwave has placed unprecedented pressure on emergency services in southwest England, with ambulance crews experiencing their busiest day ever as soaring temperatures led to a sharp rise in emergency calls.
The South Western Ambulance Service NHS Foundation Trust (SWASFT) revealed that it responded to 4,350 incidents on the hottest day recorded in the UK during June, marking the highest level of demand in the service’s history. Officials said the extreme heat created pressure “beyond anything it has ever experienced” and warned that increasingly frequent heatwaves could become a major challenge during future summers.
The record demand came as temperatures reached historic levels across parts of the UK. On 25 June, Somerset recorded a temperature of 36.7C, which was then surpassed the following day when Suffolk reached 37.3C. The intense heat prompted health warnings and increased calls from people struggling with heat-related conditions.
Ambulance leaders told local authorities that changing weather patterns mean emergency services must prepare for repeated periods of extreme heat. SWASFT said it is introducing summer response plans similar to the preparations usually used during winter pressure periods, when hospitals and emergency services traditionally experience higher demand.
Officials also urged the public to use emergency services responsibly, warning that some 999 calls were linked to less serious issues such as sunburn, feeling overheated, and mild dehydration caused by alcohol consumption. They stressed that ambulance resources must remain available for life-threatening emergencies.
The service’s previous busiest day occurred just one month earlier on 26 May, when crews responded to 3,941 incidents during another period of hot weather. The latest figures demonstrate the growing impact of extreme temperatures on healthcare systems.
With millions of people expected to visit southwest England during the summer holiday season and further hot weather forecast, emergency planners are preparing for continued pressure. Leaders said the service is taking steps to ensure it remains resilient, including adjusting staffing plans and improving readiness for periods of extreme demand.
Climate experts have warned that heatwaves are becoming more frequent and intense, creating new challenges for public health systems across the UK. Older people, young children, and those with existing health conditions are among the groups considered most vulnerable during periods of extreme heat.
As temperatures continue to rise, health officials are encouraging people to stay hydrated, avoid prolonged exposure to direct sunlight, and check on vulnerable family members and neighbours. Emergency services say public awareness and responsible use of resources will be essential in managing future heat-related pressures.
