Abstract Background Implementing universalism is more a political than a technical project. With this in mind, Ireland devised a ten-year plan through political consensus to deliver universal healthcare - Sláintecare. The COVID-19 pandemic occurred early in its implementation. Methods This is qualitative research drawing on international literature on universal health system reform in the context of COVID-19 as well as the politics of health reform. The overall research programme is co-produced with the Irish health system. A timeline and analysis of the reform journey is drawn from documentary analysis of key policy documents, parliamentary reports and key informant interviews. Results Despite a policy commitment since 2005, universal healthcare implementation only became government policy in Ireland 2018. While whole system reform and implementation progress has been slow, the COVID-19 health system response boosted aspects of universalism and reform. All COVID-related services during the pandemic were universal, free at the point of delivery, as are most new services introduced since 2021. Despite the political consensus holding through a change government and the pandemic, and significant additional investment in the public health system, there remain many obstacles to reform. These include different stakeholder understanding of implementing universalism in Ireland especially in the context of COVID-19, how best to implement universal healthcare and the politics of delivering reform. Conclusions Contrary to other countries’ experience during COVID, Ireland pursued its policy aim of delivering universalism and expanded services provided universally, free at the point of delivery, with a focus on enhanced community care. The universalism applied to COVID-related prevention and care, new women’s health and chronic disease management services. Despite progress, government has yet to legislate for a universal entitlement to care and obstacles to reform implementation remain.
