Despite a growing literature on entrepreneurial intentions, there remain gaps in the understanding of how these are affected by the age of later working-life social entrepreneurs. This research examined the ‘over-50s’ social entrepreneur understandings of age as an antecedent of their social entrepreneurial intentions. In-depth interviews were conducted with 28 UK-based social entrepreneurs. Our findings demonstrate that social entrepreneurial intentions in later working-life are influenced by an interplay of necessity, fulfilment and experienced later life, age being perceived as a positive construct rather than as a barrier. Our research contributes to the social entrepreneurship and small business literature by enhancing and advancing current knowledge and theorisation of the social entrepreneurial intentions of the over-50s. We reveal first, how social entrepreneurs make sense of their older age and the influence of their social entrepreneurial intentions; and second, how these social entrepreneurial intentions are formed by the intertwining of necessity, fulfilment and experienced later life.
