The authoritative trade body for the UK digital advertising industry, setting standards, measuring spend and lobbying on policy

IAB UK (Internet Advertising Bureau UK) is the leading trade association for the UK's digital advertising ecosystem. It represents a broad membership spanning media owners, publishers, agencies, ad tech companies, platforms and brands, with advertisers able to join free of charge. The organisation sets industry standards, conducts research, and advocates on behalf of its members on regulatory and policy matters affecting digital advertising in the UK. A flagship initiative is the IAB Gold Standard, a certification programme designed to improve the digital advertising environment by tackling ad fraud, enhancing brand safety, and improving the consumer ad experience. IAB UK also produces authoritative measurement of UK digital advertising expenditure in partnership with PwC, making it the definitive source for industry spend data. Jon Mew has served as Chief Executive since 2017, providing consistent leadership through significant regulatory and market changes. IAB UK plays a central role in shaping advertising policy, engaging with government and regulators on issues such as advertising restrictions, data privacy, and online safety legislation. It is part of the global IAB network and a member of IAB Europe's federation of national IABs, enabling it to align UK standards and positions with broader European and international frameworks. The organisation is funded primarily through membership fees and event revenues.
