Third City

Third City is one of London’s leading independent PR agencies and a certified B Corp. We work at the intersection of brand, reputation and societal change, helping organisations build relevance, trust and long-term value in fast-moving markets. We call this approach Comms for a New Economy. For more than a decade, we’ve delivered creative, insight-led communications for brands like Block, Bupa, Siemens, Curaleaf, Quilter, ABI and Rakuten, alongside government, regulatory and not-for-profit clients. Our work has been recognised across more than 30 consumer, health and retail communications awards in 2025, when we were also named Sustainability & Purpose Consultancy of the Year by PR Moment. Collaboration sits at the heart of how we work. Alongside our core team, we’re growing the Third Citizens network, a collective of like-minded partners in the UK and internationally, spanning PR, academia, social research, planning and data science, bringing broader perspectives and deeper insight to the complex challenges our clients face. We are accredited under the PRCA's Consultancy Management Standard and as a Living Wage Employer.
