The Commission opened a call for evidence on gambling with credit cards in February 2019 to consider the issue further. In August 2019, a public consultation followed to explore the options of either 1) banning the use of credit cards for gambling entirely (including online betting, casinos, bingo, lottery, and bookmakers), or 2) introducing limits and restrictions on the use of credit cards. This report provides the best available evidence on the effectiveness and considerations of implementing a ban or restriction on credit card use to gamble. It will be used to inform an evaluation plan that will measure the impact of the regulatory intervention. This report consists of two independent activities. Section 1 is a review of data on credit card use supplied by the Remote Gambling Association (RGA) and the Gambling Commission. Specifically, this data was investigated to provide insights and context around the current use of credit cards for gambling in the United Kingdom.
