Ambulance Systems Indicators (AmbSYS)

BAAS: Pending

Frequency: Monthly

Background to the collection

In 2017 the NHS England Ambulance Response Programme agreed an updated set of Systems Indicators for the eleven Ambulance Services in England with Ambulance Services and other stakeholders. These supersede the Systems Indicators that commenced in 2011. They cover the new Ambulance categories C1 to C4 rolled out nationwide in 2017, which replaced the previous Red 1, Red 2 and Green categories. They include mean and 90th centile response times for those categories; incidents closed on the call, or at scene; 999 call answer times; and allocations of vehicles.

These Systems Indicators are published monthly alongside Ambulance Clinical Outcomes at

This site also contains Statistical Notes describing the data, a collection and publication timetable, links to similar data, and the data specification.
