NHS Barnet, formerly known as Barnet PCT, looks after the health care of approximately 367,000 people in Barnet. The co-ordination of local primary care health services, such as family doctors (GPs), pharmacists, dentists and midwives, is led by Primary Care Trusts (PCTs). Primary Care Trusts like NHS Barnet are responsible for ensuring that the most appropriate primary health services are provided and giving front line staff and the public more say in how to provide local health services for the community.  To do this job, NHS Barnet is responsible for managing a budget of £414 million.

NHS Barnet has four main functions

• To address health inequalities and provide more accessible, higher quality services.
• To commission (buy) hospital and health services on behalf of the local population.
• To provide a focus for the development and involvement of primary care.
• To provide community-based and specialist health services for children and adults from community hospitals, health centres and clinics, GP surgeries and within people's homes.
