Advertising
& Marketing

We advise agencies, production companies, global brands, creators and ad-tech intermediaries on the legal and commercial aspects of advertising, media buying and digital marketing. From fast-moving campaigns to long-term strategic partnerships, we help clients manage risk, stay compliant and focus on creativity and results in a rapidly evolving regulatory and technological landscape.

Our cross-sector insight gives our clients a unique advantage as advertising, content, technology and commerce continue to converge. Working with our colleagues across the firm, our Advertising & Marketing team has unrivalled access to experts across the creative industries, including music, film, TV, fashion, videogames, art, theatre and publishing.

We also work with a network of carefully selected firms around the world enabling us to provide tailored multi-jurisdictional advice where campaigns, platforms or media buying arrangements extend beyond the UK.

We understand the realities of the advertising and marketing world: tight deadlines, complex approval chains, evolving regulations and demanding stakeholders. Our advice reflects that commercial pressure. Whether you need a detailed analysis of advertising law or a clear practical answer to move a campaign forward, we provide focused, proportionate and actionable legal guidance.

Clients choose us because we combine technical expertise with an in-depth understanding of how agencies, brands and media businesses operate in practice.
