This article reports findings from a pilot study exploring the experiences of the ‘empty nest’ or ‘post-parental life phase’ among older adults in the UK, which highlight implications for social work practice. Drawing on a survey of fifty-three respondents, predominantly aged 60 and over, the study situates the empty nest within a life course framework, recognizing how midlife transitions may shape wellbeing in later life. The research is located within the context of a rapidly ageing UK population and increasing concern regarding loneliness amongst older people. Rather than approaching loneliness as inherent to ageing, the study examines how social factors, such as living arrangements, relationship status, and prior life events, may intersect with the transition to post-parental life. Six themes are identified, and findings indicate that whilst some participants experience the transition positively, others, particularly those living alone, widowed, or single, report significant emotional distress, including loneliness and reduced sense of purpose. The article argues that the empty nest constitutes an under-recognized life transition with direct relevance to social work with older adults. It concludes by outlining study limitations, alongside implications for assessment, intervention, and preventative practice, and suggests further study in this under-researched area.
