About Us
Yorkshire Ambulance Service NHS Trust (YAS) was formed on 1 July 2006 when the county's three former services merged.
We cover nearly 6,000 square miles of varied terrain, from isolated moors and dales to urban areas, coastline and inner cities.
We serve a population of over five million people across Yorkshire and the Humber and strive to ensure that patients receive the right response to their care needs as quickly as possible, wherever they live.
We employ more than 7,200 staff, who together with over 1,300 volunteers, enable us to provide a vital 24-hour, seven-days-a-week, emergency and healthcare service.
We receive an average of over 3,500 emergency and routine calls a day. In 2021-22 we responded to a total of 849,173 incidents through either a vehicle arriving on scene or by telephone advice. Clinicians based in our Clinical Hub which operates within the Emergency Operations Centre (EOC) triaged and helped around 90,700 callers with their healthcare needs.
Our Patient Transport Service made over 706,100 journeys in 2021-22, transporting patients to and from hospital and treatment centre appointments.
Our NHS 111 service helped more than 1.6 million patients across Yorkshire and the Humber, Bassetlaw, North Lincolnshire and North East Lincolnshire during 2021-22.
We abide by the NHS Constitution which establishes the principles and values of the NHS in England. View the full Constitution Document here.
