We know that meaningful internal engagement is one of the biggest drivers of job satisfaction, collaboration, productivity, and long-term business success. Creating internal comms campaigns that deliver on this is central to Mediazoo’s mission to inspire positive change, and we’re proud to once again be named PRWeek’s No.1 agency for internal communications - for the second year running. 

Catherine Anderson, Associate Director of Internal Comms and Social Media, said: 

“This recognition by PRWeek signals our continued leadership, innovation and creativity for delivering bold, human-centric, and business-critical internal communications, that help organisations connect with their people in meaningful and accessible ways.”  

Mediazoo is also celebrating two other top rankings; appearing in the Top 5 ESG communications agencies and named in the Top 50 UK PR agencies overall, a reflection of our growing influence across purpose-led and integrated communications. 

These achievements highlight the breadth and depth of our work from driving purpose-led ESG narratives to producing integrated campaigns that resonate both internally and externally.  

Andrew McLachlan, Director of Strategic Communications, said, “We’re proud to lead the way in putting people and storytelling at the heart of internal comms and to continue to be recognised as one of the UK’s top PR Agencies with a specialism in ESG. This recognition reflects the trust our clients place in us to transform how their people connect with purpose and performance.” 

At Mediazoo, it’s always story first. We dig deep to uncover what makes you unique, your purpose, your people, and the moments that matter. Our approach is always people-first, rooted in insight, and brought to life through bold, creative execution. 

Over the past year, we’ve delivered award-winning work across internal communications, ESG strategy, and digital storytelling, partnering with FTSE 100 companies, global brands, and mission-driven organisations. Whether supporting transformation, aligning culture, or building advocacy, we believe the most powerful brand stories always start from within. 

A huge thank you to our brilliant team, trusted clients, and creative collaborators who make this work possible. We are excited to build on this momentum and continue redefining what internal and purpose-led communications can achieve.
