What is actually happening in Ambulance Response Times?

Are ambulances getting there in time?

Category 2 ambulance response times peaked at 48 minutes in 2021/22 — nearly three times the 18-minute target. In 2024 the national average stands at 38.6 minutes. For stroke patients, every additional minute without treatment causes permanent brain damage. The worst-performing trust takes 12.3 minutes for Cat 1 calls against a 7-minute target.

England's ambulance services operate under two key targets: Category 1 calls — immediately life-threatening emergencies including cardiac arrests — should receive a response within 7 minutes on average. Category 2 calls, covering strokes and heart attacks, carry an 18-minute target. Both are being missed.[1] Category 2 response times deteriorated from 18 minutes in 2017 to 48 minutes at their worst in 2022, before partial recovery to 38.6 minutes in 2024.[1] For a stroke patient, 1.9 million neurons are lost for each minute without treatment — a 38-minute average means many patients routinely wait an hour or more. The primary structural cause is ambulance handover delays: over 1.8 million crew-hours were lost to queuing outside A&E departments in 2022/23 alone.[1]

Performance variation between trusts is severe. The best-performing trust achieved a Category 1 average of 7.1 minutes in 2024; the worst reached 12.3 minutes — nearly double the target.[1] Rural ambulance services are disproportionately affected: geography means a crew trapped at a distant hospital for hours can leave hundreds of square miles without emergency cover. The national average conceals a postcode lottery in emergency care that is, by definition, life-or-death. NHS England's ambulance recovery plan, launched in 2023, combined hospital discharge acceleration with additional call-handling capacity.[2] Cat 2 times have improved but remain more than twice the target, and the underlying constraints — social care capacity, A&E crowding, workforce vacancies — have not been structurally resolved.

The gap between the best (green) and worst (red) ambulance trust Cat 1 response times has widened from 0.6 minutes in 2017 to 5.2 minutes in 2024 — a postcode lottery in emergency care.

Recovery plan improves Cat 2 times — but targets still missed

9 minimprovement in Cat 2 response time since 2022 peak

NHS England's ambulance recovery plan, launched in January 2023, delivered a 9-minute improvement in average Category 2 response times from the 2022 peak of 48 minutes to 38.6 minutes by 2024. The plan combined hospital discharge acceleration, cohorting areas in A&E to reduce handover delays, and investment in additional call-handling and hear-and-treat capacity. Some trusts have seen their Cat 2 performance return close to target. However, the 18-minute national target remains more than double the current average. Experts note that sustained improvement requires structural fixes to social care, hospital capacity, and workforce that go beyond operational measures within the ambulance sector itself.
