At the heart of general practice since 1960


The Carr-Hill funding allocation formula - named after the Professor who devised it - was introduced to underpin the 2004 GP contract, replacing the previous allocation formula - the Jarman index. It is applied to practice populations to calculate the global sum GP practices receive. It includes the following factors:

  • patient age and gender (to reflect frequency of home and surgery visits)
  • additional needs: standardised mortality ratio and standardised long-standing Illness for patients under the age of 65 years
  • number of newly registered patients
  • rurality
  • costs of living in some areas
  • patient age/gender for nursing/residential consultations
