The United Kingdom has some of the most straightforward laws governing the gambling and betting industries in the world. At the same time, it offers some of the most stringent laws, restrictions, and customer protections. Unlike many countries where gambling is highly restricted on paper but unregulated in practice, the United Kingdom allows casino games and betting, but regulates them very actively.
In the following sections, we will examine the legislation concerning casinos in the United Kingdom, an industry that now generates more than £3.2 billion in gross gaming yield. There are more than 150 casinos in the UK, and the number of online licenses is growing rapidly, now exceeding 2,000.
Gambling in the UK: Historical Overview
Gambling first came under state regulation in the 1400s, when authorities restricted betting on horse races and other sports to the nobility, while the poor were limited to dice games. The Unlawful Games Act 1541 technically outlawed almost all forms of gambling, but it was never seriously enforced; only a few years later, lotteries were officially introduced through a Royal Charter from Queen Elizabeth I. The first gaming houses and clubs appeared in the late 1700s, and ever since, they have operated under various regulatory regimes.
Over the following decades and centuries, different laws were passed, amended, and repealed. Although casinos were temporarily outlawed, they continued to flourish underground. In the 1960s the UK finally legalized casino operations, and today gaming establishments are open to anyone aged 18 or over. The main regulatory authority is the Gambling Commission, which oversees all forms of gambling (except spread betting) on behalf of the government’s Department for Culture, Media and Sport (DCMS).
The Gaming Act of 1968

The Gaming Act of 1968
The Betting and Gaming Act 1960 legalized private casinos for the first time, although it was very restrictive. These casinos were licensed by the Gaming Board of Great Britain and had to operate as members-only clubs where no more than 10 gaming machines could be installed. Casino Club Port Talbot in Wales is believed to have been the first legal casino in the UK.
The law was later liberalized with the passage of the Gaming Act 1968. It allowed larger casino establishments to operate with more gaming machines and granted patrons easier access. The Act continued to bar anyone under the age of 18 from casino gambling.
Gambling Commission
The Gambling Commission (UKGC) was created under the Gambling Act 2005 and assumed authority over all commercial gambling in the UK in 2007. It is an independent agency and an executive non-departmental public body sponsored by the Department for Culture, Media and Sport (DCMS). Its headquarters are in Birmingham, and it has more than 300 employees.
Under Section 20 of the Gambling Act 2005, the Commission replaced the Gaming Board for Great Britain and now has jurisdiction over arcades, betting, bingo, casinos, slot machines, and lotteries. It also regulates the remote gambling sector, which includes online bookmakers, bingo sites, and casino websites. On 1 October 2013 the National Lottery Commission was abolished, and its responsibilities – including monitoring and regulating the National Lottery – were transferred to the Gambling Commission. The UKGC has no authority over spread betting, which is regulated by the Financial Conduct Authority.
The Commission’s main responsibilities include licensing: it issues licenses to operators, can revoke them, and can levy fines for legislative violations. The agency has investigative powers and may prosecute illegal gambling operations. Additionally, it advises the government and local authorities on various gambling-related issues and may recommend amendments to the current legislative framework. It is also responsible for monitoring and supervising all gambling operations and can carry out inspections and inquiries.
Gambling Act 2005
The main piece of legislation that regulates both land-based and online casinos in the UK is the Gambling Act, passed in 2005 by the Parliament of the United Kingdom. It governs all forms of gambling in England, Scotland, and Wales. The Act established the Gambling Commission and transferred licensing responsibilities from the magistrates’ courts to local authorities and Scottish licensing boards.
Considered the most significant overhaul of the country’s gambling industry since the 1960s, the Act sets out three main objectives. First, it aims to ensure that all gambling is conducted in a fair and open way. Second, it seeks to prevent gambling from being linked to any form of criminal activity. Finally, it focuses on minimizing the negative impact of gambling on society by protecting children and other vulnerable groups from problem gambling.
The law places no restrictions on casino patrons; they are free to play casino games without a license and do not need to pay taxes on profits generated from gambling activities. Of course, the minimum age requirements remain. Online casino operators are required to carry out age and identity verification procedures (updated in 2019) for all newly registered customers.
The Gambling Act 2005 has a very different impact on operators. Notably, it does not differentiate between land-based and remote operations: casinos are defined as “an arrangement whereby people are given an opportunity to participate in one or more casino games“. Casino games are described as “games of chance“, which are distinct from equal chance gaming. All casino operators must obtain a license from the Gambling Commission, and their profits are subject to taxation depending on the type of game they offer. Games such as roulette, poker, and blackjack may be taxed at rates ranging from 15% to 50%. Land-based slot machines are taxed at rates between 5% and 25%.

Casino Licenses
The Gambling Commission issues several types of licenses for the casino industry, including operating licenses (such as a gambling software operating license), personal licenses for croupiers, and premises licenses, which are usually granted by local authorities. Among these, operating licenses are the most important for the casino sector.
Casinos may be classified as small, large, or regional. Regardless of size, each must meet specific licensing requirements. When deciding whether to grant an operating license, the Gambling Commission considers a range of factors, including the “applicant’s integrity, competence, and finances (including source of finance)” as stated in the Guidance to licensing authorities.
Casino Games
Casino games are a specific subset of games of chance that may be offered only in casino premises; they are distinct from equal-chance games. According to the Guidance to licensing authorities issued under the Gambling Act 2005, equal-chance gaming is “gaming which does not involve playing or staking against a bank, and where the chances are equally favourable to all participants”.
Currently, no casino games are banned in the UK. The Commission has published the rules for the most popular titles, including roulette, three-card poker, blackjack, punto banco, and dice games.
Gaming Machines
Another category of games available in casinos is gaming machines. They can be classified as Category A, B, C, or D, and under Section 236 of the Gambling Act 2005, Category B machines are further divided into subcategories. The different categories are defined by the maximum stake and the maximum prize a game can deliver, and these limits have been updated several times since 2005. Each category is permitted in specific types of premises, with Category A and B1 machines available “only in the highly regulated environment of casinos“.
The number of gaming machines a casino may host depends on its classification. Small casinos may offer up to 80 machines from Categories B, C, or D, whereas large casinos can host a maximum of 150 machines from those categories. Regional casinos are permitted to have up to 1,250 machines from Categories A, B, C, or D.
Protection of Children and Young Persons
Because one of the main objectives of the Gambling Act 2005 is to protect children from gambling, the Commission has implemented a range of measures to prevent underage play. These measures are outlined in the Licence Conditions and Codes of Practice, documents that the UKGC issues and updates regularly.
Under these rules, casino operators must deny access to anyone under 18. To enforce this requirement, each entrance to a casino must be staffed by a door supervisor. For online casinos, age-verification procedures are mandatory: operators must ask new account holders to provide copies of government-issued IDs showing name and age, along with proof of address such as a recent utility bill.
All casino games, without exception, may be played only by persons aged 18 or over. When it comes to gaming machines, however, the law sets no minimum age for Category D machines. All other machines, namely Categories A, B, and C (including Category B3A lottery-style machines), are restricted to those aged 18 and over.
Gambling (Licensing and Advertising) Act 2014
The Gambling Act 2005 has been amended multiple times over the past 15 years. The most important updates were introduced through the Gambling (Licensing & Advertising) Act 2014. It introduced several major amendments, most notably the requirement that all offshore gambling companies apply for a license from the Gambling Commission.
Additionally, foreign operators from whitelisted gambling jurisdictions were required to pay a 15% point-of-consumption (POC) tax on gross profits.
Whitelisted Gambling Jurisdictions
Until 2014, when amendments to the Gambling Act were made, operators licensed in certain countries could advertise their services and provide gambling facilities in the UK without an additional license from the UKGC. Casino and betting firms from countries outside the UK and Gibraltar were not allowed to advertise in the UK unless they were from these so-called whitelisted gambling jurisdictions: EEA countries, Alderney, Antigua and Barbuda, Gibraltar, the Isle of Man, and Tasmania.
However, the Gambling (Licensing and Advertising) Act 2014 brought changes to the licensing regime for operators. Now, all firms that wish to advertise and provide gambling services to customers based in the UK must obtain a license from the UK. They must apply for either a new authorization or a continuation of their license.
Advertising Rules for Gambling Ads
One of the most important aspects of gambling regulation in the UK is the advertising and marketing of these products. The current rules are underpinned by the Gambling Act 2005 but are detailed in the UK Advertising Codes issued by the Committees of Advertising Practice (CAP). These codes are administered by the Advertising Standards Authority (ASA), a self-regulatory, non-government organization that serves as the main advertising regulator in the UK.

Advertising Standards Authority (ASA)
The ASA was established in 1962 by the advertising industry to adjudicate complaints based on the newly published British Code of Advertising Practice (the CAP Code). Today, the Authority (although not a public authority in the usual sense) is responsible for regulating “the content of advertisements, sales promotions and direct marketing in the UK“.
It is a self-regulatory body, meaning its operations are funded not by the government but by a voluntary industry levy. Although it cannot enforce legislation, it can compel firms to remove ads that violate the CAP Code.
Advertising Rules
The gambling and betting advertising rules are designed to ensure that ads are socially responsible. They apply to both direct advertising by gambling operators and affiliate marketing. All rules are listed in detail on the ASA’s official website.
For example, gambling ads may not target children or young people under 18. They cannot promise guaranteed winnings or suggest that gambling can solve financial or personal problems. Advertisers must instead promote responsible gambling and clearly state that all gambling involves risk.
Remote Gambling
The Gambling Commission regulates not only land-based casinos and gambling premises but also the entire remote gambling sector. This includes all online casinos, both UK-based and offshore, that wish to offer their services to patrons in England, Wales, or Scotland. According to the official website of the UKGC,
Gambling websites trading with, or advertising to, consumers in Britain must have a Gambling Commission license.
The remote casino operating license allows operators “to offer casino games to customers via a website, mobile phone, TV or other online service. This includes poker, roulette, blackjack, and other casino games, as well as online slot games.” In addition, all online casinos must use software from suppliers that hold a license from the Gambling Commission. The remote gambling software license is mandatory for all companies that manufacture, supply, adapt, or install gaming software on the websites of UKGC licensees.
GAMSTOP
Ban on Gambling with Credit Cards
GAMSTOP
In general, there are no separate laws for remote gambling; online casinos must follow the same rules and regulations established for land-based establishments in the Gambling Act 2005. There are some exceptions. Online casinos, for example, must prevent underage gambling, display the return-to-player (RTP) percentages for all games, and promote fair and responsible gambling.
Facilitating self-exclusion is mandatory. All online casinos must participate in the multi-operator self-exclusion scheme GAMSTOP, the UKGC announced in January 2020. By 31 March all operators were required to join. GAMSTOP is a free service for all residents of Great Britain and Northern Ireland, allowing them to register online and exclude themselves from all UK gambling sites for at least six months. The scheme is operated by a not-for-profit organization called The National Online Self-Exclusion Scheme Limited.
Stake Limit on Fixed Odds Betting Terminals

One of the most popular types of gambling machines in the UK is the fixed odds betting terminal, or FOBT. The Gambling Act 2005 classifies FOBTs as
Category B2 gaming machines, and they are a type of electronic slot machine in which the outcome has fixed odds. The RTP is always displayed on the machine, and it is usually between 90% and 94%. Popular FOBTs in the UK include electronic versions of roulette.
Originally, the Gambling Act 2005 determined that the minimum amount that could be wagered per spin was £1, while the maximum stake was £100. In May 2018, however, the Department for Digital, Culture, Media and Sport (DCMS) announced that the maximum stake would be lowered to £2 per spin. The new regulations came into force on April 1, 2019: the maximum single bet was reduced to £2, while the maximum prize remained £500.
The move came after rising concerns about the addictive nature of these games. Similar to standard slot games or fruit machines available only in the highly regulated environment of casinos, FOBTs are also offered in betting shops and at tracks with pool betting. Moreover, critics claimed that the previous maximum stake per game led to significant financial losses for gamblers.
