When the call queue stops getting shorter, a certain silence descends upon an ambulance control room. The phones never stop ringing. Crews continue to move. However, the numbers on the screen that indicate exceptional jobs continue to rise. When South East Coast Ambulance Service declared a critical incident at 22:40 on Thursday night, it was approximately at that point.
By Friday morning, Secamb was using remarkably straightforward language. The service, which serves Surrey, Kent, and Sussex, reported that it had just finished one of its busiest days of the year. The number of unanswered calls was growing. Higher acuity, where minutes count, was present in some of them. According to Strategic Commander James Pavey, callers with less serious conditions should anticipate longer wait times as the emphasis has shifted to life-threatening emergencies.
On paper, it sounds like a procedural statement. In reality, it alters a region’s healthcare system for several days.
This time, the trigger was a well-known combination. a series of challenging shifts. persistent demand throughout the entire NHS. Then there’s heat, which always affects ambulance services in an odd way. First to struggle are older patients. Then the dehydration calls, the falls, and the seemingly insignificant cardiac events begin. The pattern is familiar to anyone who has worked with emergency services. On their own, hot weeks hardly ever break records. When the system was already under pressure, as the NHS has been for many years, they broke records.
The openness with which Secamb is requesting assistance from the public is noteworthy. The request is straightforward: only dial 999 in an actual emergency. For everything else, contact NHS 111 by phone or online. See a doctor, a pharmacist, or an urgent care facility. There’s a reason why it reads more like a community appeal than a press release. The service is well aware that many of its daily calls don’t require an ambulance at all, and every preventable dispatch is actually delayed during a critical incident.

The minute details reveal the strain. Pavey points out that instead of having a crew sent, some patients might be clinically evaluated and told to look for alternative care. That’s not new, but it’s stated more clearly now. There has been a subtle change in the way ambulance services communicate with the public—less assurance and more candor about what they can and cannot do on any given day.
It’s difficult to ignore the fact that this isn’t an isolated incident. Critical incidents have previously been reported by Secamb. Similar actions have been taken by other trusts throughout England, sometimes in response to winter pressures and other times during heatwaves like this one. Similar to how rail delays or storm warnings used to be, the pattern is becoming a part of the season. Demand continues to rise. The labor force continues to grow. In between the two, a service is attempting to prioritize both its own capacity and patients.
During a week like this, you can practically feel it if you walk by any A&E in the area. Outside, paramedics silently checked their watches as ambulances lined up and crews waited to hand over. Inside, employees have long since stopped responding to the term “critical incident” due to their frequent exposure to it.
According to Secamb, the heat is predicted to subside in the upcoming days. It cautions that demand probably won’t. Until conditions return to something approaching normal, the service intends to maintain all available measures. But it’s worth considering what “normal” means today. Because a single hot week isn’t the main source of pressure on South East Coast Ambulance. It’s about the public being gently asked to pay attention while a system is asked to do more, with less margin, year after year.
As of right now, Kent, Sussex, and Surrey have a clear and concise message. Have some water. Two doors down, see how the elderly neighbor is doing. Save 999 for the times when you really need it. The crews will continue as usual.
