The Advertising Standards Authority (ASA) is the UK's independent body responsible for ensuring advertising is legal, decent, honest, and truthful. It administers the UK Advertising Codes, which cover all forms of media including TV, radio, print, online, and direct marketing. The ASA investigates complaints about ads, takes action against misleading, harmful, or offensive advertising, and works to ensure a level playing field for businesses and maintain consumer trust. It is funded by a levy on the advertising industry, operating independently of both government and the industry itself.
Serves as the main operational hub for the ASA, housing its administrative, regulatory, complaints handling, policy-making departments, and engagement functions.
Located in Castle House, a modern office building in London's tech and creative hub near Old Street. Office space is functional, designed to support an efficient and collaborative work environment for its regulatory duties.
A professional, diligent, and mission-driven work culture focused on upholding advertising standards with fairness and transparency. Emphasizes collaboration, expert knowledge, and public interest commitment.
The London headquarters is pivotal for the ASA's national regulatory operations, complaint adjudications, policy development, and stakeholder engagement with the advertising industry, government, and consumer groups.
While the ASA's direct regulatory remit covers advertising within the United Kingdom, it actively participates in international networks of advertising self-regulatory organizations. This includes collaboration with bodies like the European Advertising Standards Alliance (EASA) and the International Council for Ad Self-Regulation (ICAS). Through these networks, the ASA shares best practices, contributes to discussions on cross-border advertising issues, and promotes the principles of effective advertising self-regulation globally. They also engage with international counterparts on emerging advertising trends and regulatory challenges.
