General Practitioners are independent contractors to the NHS and work under legal agreements that determine the services that must be delivered to patients under their care and how. These contracts which are often referred to as the core contract are held between NHS England (the purchaser or commissioner of the service) and the primary care contractors or provider of the service.  Currently, the contracting mechanisms for the core contracts are the GMS, PMS and APMS contracts.

In addition to the core contract there are a number of other smaller contracts that enhance the level of service offered by General Practitioners.  These enhanced services are known as Community Contracts and are commissioned by either NHS England, NHS Doncaster CCG or the Doncaster Local Authority (via Public Health).

The enhanced service contracts currently available in Doncaster are listed below.
