Third City is one of London's leading independent strategic communications consultancies and a certified B Corp, wholly owned by its founders and employees since 2011. 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.

We deliver creative, insight-led communications for brands including Kia, Siemens, HSBC, Nespresso, Dr. Martens, Curaleaf, Block, The Royal Mint and SunLife, alongside government, regulatory and not-for-profit clients.
Third City is one of the most recognised independent agencies in the UK. 

In 2025, we won 15+ major awards and earned 50+ shortlistings, and were named Sustainability & Purpose Consultancy of the Year. In 2026, we were named GEO Agency of the Year at the PRmoment Awards and Agency of the Future at the PRovoke EMEA IN2 SABREs. We are listed among PRovoke's 50 Best Agencies in the UK and Top 100 Corporate PR Agencies in the World.

We are one of the first UK agencies to offer a dedicated Generative Engine Optimisation (GEO) service, backed by proprietary auditing tools and over £150K in R&D investment. Alongside our core team of 27, we work with the Third Citizens network — a collective of partners spanning PR, academia, social research, planning and data science.

We are accredited under the PRCA's Consultancy Management Standard, a Living Wage Employer, and were re-certified as a B Corp in January 2025 with a score of 95.2.
