Public policy increasingly emphasises the importance of informal support networks to meet the needs of the ageing population. Evidence for the types of support neighbours provide to older people and how neighbours collaborate with formal support-givers is currently insufficient. Our study therefore explored (i) types of informal neighbour support and (ii) experiences of neighbours, volunteers and professionals providing support. Interviews with nine Dutch neighbour support-givers, five volunteers and 12 professionals were conducted and subjected to latent content analysis.
