Carelink is a service provided by North Somerset Council that supports vulnerable people to live independently at home through an easy-to-use monitored alarm system. The demographic of the area was changing with an aging population and increasing costs for adult care. The council conducted small-scale research and profiling of customers to identify four target groups to focus their marketing on to increase awareness of Carelink. This approach led to a large number of new customers and over 95% customer satisfaction. It is estimated that for every new Carelink customer, the council saves around £13,000 per year in residential care costs, yielding significant savings.
