The Covid-19 pandemic reduced research collaborations with public contributors and prevented face-to-face interaction. The formation of Researcher Coffee Mornings within the Wessex region aimed to continue relationships between the research community and public through the pandemic. Researcher Coffee Mornings were regular Zoom meetings run by public involvement staff at University Hospital Southampton NHS Foundation Trust, UK. They were created to provide pastoral support and ‘check-ins’ between staff and public contributors during the Covid-19 pandemic. Reorganisation, implemented by public involvement staff but led by public contributors, meant that the events evolved over time. The Researcher Coffee Mornings were a means to share updates about research with the public. They were a safe space for involvement staff, researchers and the public to exchange knowledge and share experiences. This article highlights the intended and unexpected benefits of investing in relationships. We reflect on these benefits through the perspectives of the public involvement staff, public contributors and researchers. Investing in relationships has brought value to everyone involved. By demonstrating the benefits of providing regular, inclusive spaces for relationship building between the research community and public contributors, we hope to encourage others to invest in relationship building in their settings, to improve public involvement practices.
