Are Prize Competitions Legal in the UK? The Rules Explained

Quick answer: Yes, prize competitions are legal in the UK: the Gambling Act 2005 treats paid entry plus prizes plus an outcome decided wholly by chance as a lottery, and competitions stay outside that definition by adding a genuine skill element or a free entry route. Rules still apply, and this is not legal advice.

Key takeaways

The legal test is simple to state: pay to take part, prizes on offer, and a winner decided wholly by chance is the shape of a lottery under the Gambling Act 2005 frame.
UK competitions remove one element of that shape: a genuine skill question makes the player's answer part of a valid entry, and a free entry route, usually by post, means nobody has to pay to take part in a chance-based draw.
Run properly, both formats sit outside gambling licensing, but advertising rules still apply, the DCMS voluntary code sets good-practice standards for prize draw operators, and each competition lives by its published terms.

You do not have to take this on trust: our competition terms cover the free route, the eligibility rules and how draws run, and new players can claim free tickets to see a real game before spending anything.

Are prize competitions legal in the UK?

Yes. Prize competitions are legal in the UK when they are run to the rules, and the rules come from a clear structure: the Gambling Act 2005 defines what makes a lottery, and a properly run competition either adds a real skill element or offers a free way in. This is general information, not legal advice.

Three layers matter in practice:

The boundary in the law. The definition of a lottery, and what sits outside it, is where every UK competition is positioned. That is the frame used here.
The promotion rules. Advertising and promotional mechanics, including free entry routes, are covered by the CAP Code, which the ASA enforces.
The terms of each competition. Dates, eligibility, entry limits and prize details are set by the operator's published terms, and those terms are what apply to your entry.

Laws and codes can change, so check the terms in front of you and, for anything specific to your situation, professional advice. MrRaffle is for UK residents aged 18 and over.

What makes a prize competition different from a lottery?

The difference is structural, not cosmetic. A lottery under the Gambling Act 2005 frame has three parts: people pay to take part, prizes are offered, and the winner is decided wholly by chance. A competition changes one part: it makes the outcome depend on more than pure chance, or it removes the need to pay.

The table below sets the three formats side by side.

Format	Entry cost	How the winner is decided	What changes the picture
Chance-based prize draw	No payment required: a free route, usually by post, must be available	Chance	A genuine free entry route
Competition with a skill question	Usually paid, with a free route where the terms offer one	A correct answer is part of a valid entry, then the remaining process runs	A real skill element
Lottery	Paid entry	Wholly by chance	Nothing takes it outside the lottery definition

Names on the tin vary: raffle, prize draw and competition are marketing words, and the legal test looks at the structure underneath rather than the label. Our explainer on raffles versus prize draws versus lotteries walks through the naming in more detail.

Why do competitions need a free entry route?

A free entry route answers the payment part of the lottery test. In a draw decided by chance, if the only way in is to pay, the arrangement looks like a paid lottery, so operators offer a genuine alternative, usually by ordinary post, that counts as one entry in the same draw.

In practice a free route works like this:

The terms publish how to enter without paying, what to include, and the closing date.
One postal entry usually goes in one envelope, with entry limits per person or household.
A free entry counts the same as a paid one in the same draw, with the same chance as any other entry.

That last point is not a favour: counting the same is what makes the route genuine. Our guide to free postal entry competitions covers the practical side. On MrRaffle, paid chance-based draws carry a free postal entry route, and the competition terms set out how it works.

Why do competitions ask a skill question?

Because a genuine question removes the wholly-chance condition: when success depends on the player supplying the right answer, the outcome is not decided by chance alone. That is why competition questions are usually easy but real, and why a wrong answer makes the entry invalid.

A question does the legal work when:

It can be answered wrongly, and a wrong answer invalidates the entry.
The player, not a random draw, supplies the answer.
It is more than decoration: a formality that could never change the outcome does not move the competition outside the chance-based definition.

Free postal entries answer the question too, where a competition has one, so both routes pass the same check. Our explainer on why competitions have skill questions goes deeper.

The question, the free route and the entry rules all meet in the terms: read how ours handle each one on the competition terms page, or claim free tickets as a new player and try a game first.

Who regulates prize competitions?

There is no single regulator that approves each competition. Arrangements that stay inside the rules sit outside gambling licensing, advertising is covered by the CAP Code enforced by the ASA, and the DCMS voluntary code sets good-practice standards for prize draw operators.

The layers fit together like this:

The law sets the boundary. The Gambling Act 2005 frame decides whether an arrangement is a lottery or sits outside that definition.
The advertising codes cover the promotion. How a competition is described, including the free entry route, is subject to the CAP Code, and the ASA can act on complaints.
The voluntary code covers conduct. The DCMS code for prize draw operators sets expectations on things like transparency and how draws are presented, for operators who commit to it.
The terms cover your entry. The operator's published terms define the competition, including dispute processes.

If an arrangement is not run to the rules, it can fall to be treated as a lottery, which brings licensing and regulation into play.

How do you check a competition is run legally?

Five checks cover most of it: read the terms, look for the free route on any chance-based draw, check that a skill question is real, confirm the prize list and closing date are published, and check how winners are announced. If something important is missing, enter somewhere else.

The checks, in order:

Read the terms before anything else: entry dates, eligibility, entry limits, and what happens if there is a dispute.
Find the free route: a chance-based draw should offer a genuine way in without paying, spelled out in the terms.
Test the skill question where one applies: it should be answerable, required, and capable of being got wrong.
Check what is published: the prize list, the closing date, and the odds and remaining prizes where the format shows them.
Check the winners trail: an operator that publishes previous winners, like our winners page, is easier to trust.

Red flags are worth memorising: a fee to release a prize, no published terms, or pressure to keep playing to unlock a win. Our two-minute read on how to spot a legit prize competition turns these into a checklist.

For a properly published game in practice, the how it works page walks through each format, and new players can claim free tickets to look around first.

Frequently asked questions

Is it illegal to run a prize competition without a gambling licence?

No, not when it stays inside the rules: arrangements built on a genuine free entry route, or a real skill element, sit outside gambling licensing in those forms. If an arrangement becomes a paid, wholly chance-based lottery, the licensing regime applies instead.

Do free postal entries really count the same as paid entries?

Yes. A genuine free route puts your postal entry into the same draw as paid entries, counting as one entry with the same chance, and the terms explain how it works. Entry caps, deadlines and eligibility rules still apply, and one entry per envelope is the usual format.

Can a skill question be easy and still count?

Yes. A question can be easy and still do the job, as long as it is genuine: the player has to supply the correct answer, and a wrong answer invalidates the entry. A question that could never change an outcome does not move the competition outside the chance-based definition.

What happens if a competition breaks the rules?

At a high level, the arrangement can stop sitting outside the lottery definition, so the rules that apply to lotteries can come into play, and promotions can also be challenged under the advertising codes.
