This paper reviews the challenges faced by unpaid family carers and the current support and services available to them. It argues that current carer support should be built on and presents the evidence for doing so, including evidence of the opportunities to make substantial savings in residential care costs. The paper suggests a new way in which proposed resource allocation and personal budget systems could be developed in order to sustain caring, avoiding the risk of a new perverse incentive to families to end caring roles. The paper provides some modelling of the costs and benefits of this approach.
