Advertising Standards Authority

The Advertising Standards Authority or ASA is the United Kingdom's advertising regular; it investigates and rules on misleading, harmful, offensive, or irresponsible advertising including health and beauty products, medical claims about products or services, and other advertising. It rules on internet, social media, influencer, magazine and print adverts, plus TV and radio advertising.

Committee of Advertising Practice
The Committee of Advertising Practice (CAP) writes codes that advertisers must abide by, and the published codea are available on the ASA website.

Legal powers
The Advertising Standards Authority can insist an advert is withdrawn or amended - including text or images on a website - but does not have enforcement powers. When enforcement is felt necessary, the ASA refers the case to local UK Trading Standards, who are then able to prosecute.
