Fostering sustainable consumer behaviour: Unravelling the determinants of repair intentions for smart appliances

Consumer demand for repair services is vital for prolonging product lifespan, yet factors influencing the repair intention for smart appliances remain unclear. Addressing this gap, we propose an extended theory of planned behaviour, incorporating four additional constructs: environmental knowledge, cost of repair, financial benefit, and data security. We collected data from 383 participants in the United Kingdom, which we analysed using a partial least squares approach. Results reveal that the cost of repair, perceived behavioural control, attitude, and financial benefit directly impact repair intention, while subjective norms do not. Environmental knowledge indirectly influences repair intention through attitude mediation, and data security's impact is not moderated by attitude. This extended theory offers a theoretical foundation for future related studies, providing insights for repair providers, environmental NGOs, and policymakers. Our findings can inform interventions promoting repair behaviour and guide policies incentivising consumers, thus increasing the demand for repair services. •We explore factors influencing repair intention for smart appliances in the UK.•An extended theory of planned behaviour model is proposed with additional constructs.•Cost of repair, perceived control, attitude, and financial benefit impact repair intention.•Environmental knowledge indirectly influences intention via attitude; data security does not.•Findings provide insights for repair providers, environmental NGOs, and policymakers.
