The Gambling Act 2005 is the main UK law for regulating gambling. It sets out the core concepts of gambling, remote gambling, gaming, betting, lotteries and gaming machines. It also creates the main licensing structure, gives functions to the Gambling Commission and local licensing authorities, and creates offences for unlawful gambling activity.
For a business owner, the key point is that the Act is not limited to traditional gambling venues. It can apply to online services, software, promotions, clubs, pubs, fairs, machine operators and societies running lotteries. If your offer involves paying to play, betting on an outcome, a game of chance, a prize draw that may amount to a lottery, or gaming machines on site, the Act is likely to be relevant.
