What happens when you call 111?  

When you call 111, you will be asked a series of questions from one of our fully trained health advisers or clinicians.  

These questions enable an assessment of your symptoms to help decide the most appropriate healthcare advice or referral to local services best suited to addressing your medical need. 

If, during the assessment, we believe you need an ambulance, we will arrange this for you and provide advice and guidance, if required, to assist in the interim period until trained 999 professionals arrive on scene. 

Depending on your symptoms, you may have been offered a callback healthcare professional such as a nurse, doctor or paramedic. Find more information about 111 callbacks on NHS.UK 

What if I need an interpreter?  

Should you require assistance, 111 services are able to provide interpreter facilities and those who have hearing impairments are able to use a relay service in order to converse with the 111 provider.
