Response times for emergency ambulance services in London have significantly improved in recent months, with the London Ambulance Service (LAS) achieving its fastest times for attending to seriously ill patients in years. This progress is largely credited to the expanded use of a "hear and treat" strategy, whereby clinicians assess patients over the phone and refer them to the most appropriate care centres. By avoiding unnecessary hospital visits, this approach has freed up substantial ambulance crew time and resources.

Since the method’s wider implementation, the LAS reports having treated nearly 275,000 patients via phone consultations, accounting for over 20% of all cases—a notably high rate compared to other regions. The benefits of this approach include quicker responses to Category 1 emergencies, which involve life-threatening situations, and Category 2 incidents such as strokes and chest pains, where urgent treatment is essential. In April 2025, the LAS recorded its fastest response to Category 1 patients since April 2022, while Category 2 responses improved by over seven minutes compared to the previous year.

These trends have continued through mid-2025. By July, average response times for Category 2 patients had improved by around eight minutes year-on-year, despite the service handling an additional 12,200 999 calls compared to July 2024. Category 1 targets were also met, with the LAS routinely reaching the most seriously ill in under seven minutes. The organisation credits these gains not only to the hear and treat system but also to increased staffing levels during one of its busiest periods.

The new NHS ambulance response system, effective from November, categorises emergency calls into four priority levels, with hear and treat forming an integral element. This system enables more efficient use of ambulance services by delivering medical advice remotely when appropriate, thereby optimising the deployment of on-the-ground crews to patients in genuine need of emergency intervention.

Despite continuing pressures, including high call volumes, the London Ambulance Service’s strategy highlights the potential of remote clinical assessment to reduce unnecessary hospital attendances, enhance patient care pathways, and improve response times for emergencies. The improvements mark a significant operational success amidst enduring challenges within the capital’s healthcare infrastructure.
