Loneliness is framed as an enduring problem for carers of all ages, including older carers; however, there is little examination of older men's experiences of caring, loneliness and social isolation. Based on interviews with 25 men (aged 68-92 years), we discuss findings from a study of older male carers' experiences of loneliness in England. Within their accounts, loneliness is framed as a future, rather than present, problem as caring provides a time-limited buffer to loneliness while concurrently increasing social isolation. Further, the findings shed light on how male carers seek and benefit from carers' support groups while also maintaining autonomy.
