Core Event
During the summer of 2026, hospitals across England experienced extreme indoor temperatures, with some wards reaching almost 42 °C. The Northern Care Alliance NHS Foundation Trust recorded 41.8 °C in a Greater Manchester hospital, far above the 28 °C limit advised by NHS England for safe patient and staff environments. Cooling units in operating theatres failed, leading to the cancellation and rescheduling of surgeries. Ambulance crews reported difficulties maintaining medication temperatures, and staff have been forced to adopt shorter uniforms to cope with the heat.
Data & Statistics
- Ward temperatures in July averaged 31.9 °C, based on freedom-of-information data from 33 NHS trusts.
- The Northern Care Alliance reported a peak of 41.8 °C; other trusts noted temperatures “almost 42 °C.”
- NHS England recorded 2.5 million A&E attendances in July, the highest monthly total on record.
- Over 150,000 A&E patients waited more than 12 hours for a hospital bed; roughly one-third of emergency admissions experienced such delays.

Official Statements & Responses
Helen Morgan, health spokesperson for the Liberal Democrats, called for a new “NHS rapid adaptation unit” to install air-conditioning and other heat-proofing measures in hospitals and care homes, describing current conditions as “dangerously hostile.”
Impact on Emergency Care
The combination of record-high temperatures and unprecedented A&E demand strained emergency departments, especially for elderly patients who faced prolonged waits in overheated settings. While overall A&E performance metrics showed modest improvement, the surge in attendances and extended boarding times highlighted the acute pressure on staff and the need for infrastructure upgrades to maintain safe care standards during future heatwaves.
