This Public Communication Scan of the United Kingdom, the first such scan of an OECD Member country, brings new insights to the OECD’s work on understanding how public communication contributes to democratic governance. The scan analyses how the United Kingdom’s Government Communication Service (GCS) is building a more effective communication function amid changes to the information ecosystem and how it can help make policymaking more responsive to citizens' needs. The analysis and recommendations in this Scan highlight opportunities for the GCS and the UK Government to align ongoing communication reforms with actions to promote more inclusive and people-centred communication that contributes to greater engagement, improved public trust, and better policy outcomes.
