Four of England's ten ambulance trusts have stated in their own operational plans that they do not expect to meet the headline emergency response time target for 2026-27. This is not a projection made by an external body or a regulator reading between the lines. It is written into the trusts' own forward-looking documents, making it a planned shortfall before the year has properly begun.

The target in question covers Category 2 calls, the classification applied to serious but not immediately life-threatening emergencies, including suspected strokes and heart attacks. The statutory standard requires an average response time of 18 minutes. That figure has not been consistently achieved nationally for several years. NHS England introduced a temporary interim target of 30 minutes as part of its urgent and emergency care recovery programme, and even that reduced benchmark is beyond the reach of several services. The national average in January 2026 sat above 35 minutes.

The East Midlands Ambulance Service recorded the worst Category 2 performance in the country in 2025-26, finishing the year nearly nine minutes above its own planned average. Its board papers describe the position as unsustainable. The trust's 2026-27 plan frames the demand pressures it faces as structural: a population that is older, more deprived, and carrying a greater burden of long-term conditions than the service was originally designed to manage at this scale. Other trusts projecting misses cite comparable pressures, and some have described the current targets as unachievable given the operating environment they face.

The single most cited operational constraint across trust plans is the time lost to hospital handovers. When an ambulance crew arrives at an emergency department and cannot transfer the patient because no space is available, the vehicle and its staff are effectively removed from the system. They cannot respond to the next call until the handover is completed. The proportion of handovers taking longer than 30 minutes rose between 2023-24 and 2024-25, and despite some national improvement, a number of trusts ended last winter above their planned trajectories on this measure. One trust's board papers noted that handover delays during the winter months had pushed its full-year position above plan, despite improvement in the spring.

The workforce picture adds further pressure. In at least one trust, the number of clinicians staffing the emergency operations centre ran significantly below planned levels through much of the year, with actual headcount less than 70 per cent of target at points. Fewer staff in control rooms means slower call handling and reduced ability to manage demand at the first point of contact. Fleet availability is also affected by vacancy rates and sickness, with some services finding that crewed vehicle hours, while broadly meeting plan, mask significant variability at a local level.

Demand itself continues to grow in both volume and complexity. Trusts describe an increasing proportion of callers presenting with mental health crises, frailty-related conditions, and multiple overlapping health problems. These cases often take longer to assess and resolve at scene, and they do not always result in a hospital conveyance, which has implications for the "hear and treat" and "see and treat" models that NHS England has been promoting as a way to reduce pressure on emergency departments. Where those models are underperforming, trusts are left managing more calls with the same resources.

The coroner system has, over recent years, issued multiple prevention of future death reports relating to ambulance delays, identifying missed responses as a contributing factor in deaths that might otherwise have been avoidable. Staff shortages, handover blockages, and insufficient resources have featured repeatedly in those findings, some of which were addressed directly to government ministers.

The government's 10-Year Health Plan sets a goal of bringing Category 2 response times to 30 minutes, a figure that is itself already a concession from the 18-minute statutory standard. No firm commitment has been made to restore performance to that original constitutional level within this Parliament. The plan includes measures intended to ease pressure on ambulance services over time, including additional urgent treatment capacity and mental health crisis provision, but the timelines extend well beyond the current financial year.

The trusts that have declared their targets unreachable are not doing so as an act of defiance. They are doing so because their own modelling, set against the resources available to them, leaves no other honest conclusion. For someone dialling 999 with a stroke, the wait they can expect already exceeds the standard the NHS has committed to meet.
