OFCOM is a regulatory body in the UK that oversees wireless and fixed line communications like televisions, radios, and mobiles. Companies must have their broadcast licenses approved by OFCOM. OFCOM also investigates complaints from the public. The BCAP code lists rules for advertisements regarding taste, decency, harm, and offense. Clearcast ensures ads comply with the BCAP code before broadcast on UK television and radio. The ASA aims to ensure ads are legal, decent, honest and truthful by enforcing advertising codes and investigating complaints.
