Third City

Founded in 2011, Third City emerged as an independent PR agency with a clear sense of purpose. Based in the London Borough of Islington, the agency was built around the idea that communications could be a force for positive change, particularly in how businesses and organisations address social, economic, and environmental challenges. From the start, the founders sought to create an agency that would not only deliver strong results for clients but also operate with a genuine commitment to ethical practices and social impact. This founding ethos has shaped Third City’s evolution into a certified B Corporation since July 2022, making it one of a growing number of PR agencies in London, United Kingdom, to meet rigorous standards of social and environmental performance.

Current Focus and Philosophy

Today, Third City describes its work as “Comms for a New Economy,” a phrase that captures its focus on helping clients navigate and shape the transition toward more sustainable, equitable, and purpose-driven business models. The agency’s approach blends corporate and consumer PR with brand strategy, digital communications, public affairs, and sustainability initiatives. With around 27 employees and an annual revenue of $5.2 million, Third City operates as a lean, independent firm that draws on a global network of collaborators, including digital strategists, data scientists, and subject matter experts. This structure allows the agency to remain nimble while delivering sophisticated, multi-channel campaigns. Third City has also built a reputation for integrating emerging talent into its work, partnering with Goldsmiths, University of London, to offer live briefs and internships that bring fresh perspectives to client projects.

Services and Specialties

Third City’s service offering is broad but deeply integrated, reflecting the agency’s belief that effective communications must be holistic. Core capabilities include brand and communications strategy, messaging, stakeholder relations, media training, and strategic communications. The agency also excels in media relations, brand positioning, and brand marketing, often working with clients to craft narratives that resonate with both traditional and digital audiences. In recent years, Third City has developed particular strength in areas such as influencer marketing, digital and social media, and content creation, helping clients build authentic connections in an increasingly fragmented media landscape. A significant portion of its work also falls under the umbrella of ESG consultancy, public affairs, and sustainability communications, where the agency advises on issues like climate action, sustainable development, social innovation, and ethical marketing. Third City’s experience in diversity and inclusion, social justice campaigns, and social impact measurement further sets it apart, particularly for clients seeking to align their brand with meaningful causes.
