Why the law matters
If you enter, run, or promote prize competitions in the UK, understanding the legal framework is important. The rules determine whether a competition is lawful, how it must be structured, and what protections consumers have. Getting it wrong can mean fines, prosecution, or your competition being shut down.
The Gambling Act 2005: the foundation
The Gambling Act 2005 is the primary legislation governing lotteries, raffles, and betting in the UK. It draws a clear line between gambling (which requires a Gambling Commission licence) and prize competitions (which do not, provided they meet certain conditions). This distinction is the foundation of UK competition law.
What makes a competition legal?
Under UK law, a prize competition is legal if it meets one of two conditions:
The two legal routes
- Skill or judgement. The competition requires participants to exercise genuine skill or judgement to enter. This cannot be trivially easy. A question like "What colour is the sky?" would not qualify.
- Free entry route. The competition offers a free way to enter alongside any paid entry option. This is typically a postal entry route where participants send a postcard with their details. The free entry must provide the same chance of winning as a paid entry.
Key distinction
If a competition charges for entry, selects winners purely by chance, and does not offer a free entry route, it is legally a lottery. Running an unlicensed lottery is a criminal offence under the Gambling Act 2005.
The free entry route in practice
Most online competition platforms in the UK operate under the free entry route model. Participants can pay for tickets through the website, but there is always a postal entry option. The postal entry details must be clearly published, and the free entry must carry the same chance of winning. Some platforms also run entirely free competitions that require no payment and no postal entry.
Who regulates prize competitions?
Prize competitions with a free entry route are not regulated by the Gambling Commission. Instead, they fall under general consumer protection law and the Advertising Standards Authority (ASA). The ASA enforces the CAP Code, which sets rules for how competitions can be promoted. Key requirements include that terms must be clear, prominent, and available before entry, and that promotions must not mislead consumers about the nature of the prize or the chances of winning.
Lotteries and raffles: different rules
Lotteries and raffles are governed by stricter rules. A lottery requires a Gambling Commission licence unless it falls under a specific exemption (such as small society lotteries run by charities). Raffles are subject to similar oversight. The key difference from prize competitions is the absence of a free entry route or skill element.

What consumers should know
As a consumer, the law gives you several protections. Paid competitions must offer a free entry route. Terms must be published and accessible. Prize descriptions must be accurate. Draw methods should be fair. If a competition fails to meet these standards, you can report it to the ASA or, in cases of suspected fraud, to Action Fraud.
How to check if a specific competition is legal
- Find the company behind the competition. Look for the company name and registration number, usually in the footer or terms. Search Companies House at gov.uk/companies-house to confirm the business is registered and active in the UK.
- Find the free entry route. Every paid prize competition must publish a clear way to enter for free, almost always a postal entry address. If you cannot find one, the competition may not be compliant.
- Read the terms and conditions before paying. They should cover the closing date, the draw method, the total ticket count or cap, the free entry instructions, and how the prize will be claimed. Vague or missing terms are a warning sign.
- Check for visible winners. A platform that has been running for a while should have a winners page or recent winner announcements. No evidence of past winners is reason to slow down.
- Check the payment route. Reputable platforms use established processors like Stripe or PayPal. If a competition asks for direct bank transfer, gift cards, or cryptocurrency, treat it with extreme caution.
When to report a competition
If you spot a competition that breaks the rules, there are three main routes for reporting. The right one depends on what is wrong. Knowing where to send a complaint is also a useful sanity check before you enter, because legitimate platforms make it easy for you to find this information themselves.
- Misleading promotion or unclear terms: report to the Advertising Standards Authority at asa.org.uk. The ASA enforces the CAP Code, which covers how competitions can be advertised and what must be disclosed before entry.
- Suspected fraud or scam: report to Action Fraud at actionfraud.police.uk, the UK national fraud and cybercrime reporting centre. This is the right route if you have lost money or had personal data taken.
- Unfair business practices, missing free entry route, or refusal to honour a prize: contact your local Trading Standards through Citizens Advice at citizensadvice.org.uk. They can also escalate to the Competition and Markets Authority where appropriate.
- Suspected unlicensed lottery (paid, no free entry, pure chance): the Gambling Commission at gamblingcommission.gov.uk handles intelligence on unlawful gambling.
Common myths about UK competition law
All paid competitions need a Gambling Commission licence
Prize competitions with a free entry route or a genuine skill element do not need one. They sit outside the gambling regime by design
A skill question can be anything, even a coin toss
The skill or judgement element must be substantive. A trivially easy question is treated as no skill at all and the competition becomes an unlicensed lottery
Free entry has worse odds than paid
The law requires free entries to carry the same chance of winning. If a platform weights the draw, it loses its lawful prize-competition status
Charity raffles and prize competitions are the same
Charity raffles fall under specific Gambling Act exemptions for small society lotteries. Prize competitions are a separate framework with different rules
Check before you enter
A well-run platform will publish its free entry instructions, terms, and draw methodology clearly. If you cannot find any of these, the competition may not be compliant with UK law.
