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.
