Running Prize Draws And Competitions To Win Money: UK Legal Rules

Competitions to win money can be a brilliant way to grow your audience, build your mailing list, and create genuine hype around your brand.

But if you’re running a money competition (or any competition where the prize has real value), you’ll want to be careful about the legal rules. In the UK, a promotion can accidentally stray into “illegal lottery” territory if it’s structured the wrong way – and that’s the kind of headache you definitely don’t need mid-campaign.

This guide breaks down, in plain English, how to run competitions to win money in the UK as a small business: what types of promotions are allowed, what rules you need, where businesses go wrong, and what to put in place so you’re protected from day one.

What Counts As A “Competition To Win Money” (And Why The Category Matters)

When people search for competitions to win money, they usually mean one of these business-run promotions:

• Prize draws (winners selected at random, e.g. “enter your email to be in the draw to win £500”).
• Skill-based competitions (winner selected based on skill/judgement, e.g. “best photo wins £1,000”).
• “Pay to enter” promotions (entrants pay for a chance to win a prize, sometimes dressed up as a “competition”).

Legally, your structure matters because the UK has strict rules around lotteries and gambling – mainly under the Gambling Act 2005. In simple terms, a promotion generally becomes a lottery if it involves:

• Payment to enter, and
• Chance determines the winner, and
• A prize is awarded.

If you’ve got all three, you’re likely dealing with a regulated lottery (and running one without the proper authority can be unlawful).

The good news is: most small business giveaways can be run legally – as long as you design them correctly and explain the rules clearly upfront.

The Three Common Legal Categories

Most consumer-facing promotions fall into one of these categories:

• Free prize draw: winner picked by chance, but entry is genuinely free.
• Prize competition: winner picked by skill/judgement, and the “skill” element is meaningful (not just a token question).
• Lottery/raffle: winner picked by chance and people pay to enter (usually regulated, and not a standard “marketing giveaway”).

If you’re unsure where your promotion sits, it’s worth getting advice early. It’s much easier (and cheaper) to restructure the campaign before launch than to fix it after complaints roll in.

How To Run A Prize Draw Legally (The “Free Entry” Rules)

A prize draw is often the easiest type of “competitions to win money” campaign for a small business, because it’s straightforward and tends to convert well.

The key legal issue is ensuring it’s not a paid lottery.

What “Free Entry” Really Means

A prize draw can usually be run lawfully if entry is genuinely free. Under UK rules, that generally means there’s no payment to enter (including no hidden “payment” via expensive entry methods), and that any free entry route is genuine and accessible.

Examples that commonly raise issues include:

• “Buy a product to enter” where purchase is the only realistic way to enter.
• Inflated pricing (e.g. the product price appears increased to cover the “entry”).
• Paid phone lines / premium SMS to enter (more likely to be viewed as payment).
• Mandatory postage costs beyond normal rates.

Many businesses use a “no purchase necessary” route (e.g. an online form entry) alongside purchase entry. The practical point is this: the free route should be clear, genuinely available, and not less convenient than any paid route.

What Your Prize Draw Terms Should Cover

Even a simple giveaway needs proper terms. Your terms aren’t just “admin” – they’re what make your promotion enforceable and reduce disputes.

Typically, your prize draw rules should include:

• who can enter (including age limits and location restrictions)
• start and end date/time (including time zone)
• how to enter (and any entry limits per person/email/IP)
• how the winner is selected (random draw method) and when
• how the winner is contacted and how long they have to respond
• what happens if the winner can’t be contacted / doesn’t respond
• the prize description, value, and any exclusions
• your right to cancel/withdraw where appropriate (carefully drafted)
• data and marketing wording (more on this below)

If the promotion is hosted online, it’s also common to build your giveaway rules into your broader Website Terms And Conditions so the full legal framework is consistent across your site.

How To Run A Skill-Based Competition Legally (And Avoid The “Token Question” Trap)

If you want to charge an entry fee (or link entry to purchase) and still stay outside lottery rules, many businesses look at “prize competitions” based on skill.

That can work – but only if the competition is a genuine test of skill, knowledge, or judgement. In practice, the bar is higher than a simple “tick box” question: the skill element should be strong enough that it’s not realistic for a significant proportion of people to enter or win without skill (or it should prevent a significant proportion of people from entering at all).

What Makes A Competition “Skill-Based” In Practice?

A proper skill-based competition usually involves something like:

• creating content (photo, video, slogan, design)
• answering a question that requires real knowledge or research
• solving a puzzle that’s not obvious or trivial
• a judged entry process with clear criteria

Where businesses get caught out is when the “skill” element is basically meaningless – for example, a question so easy that almost everyone gets it right, with the winner then chosen randomly. That can look and operate like “chance + payment + prize”, which is where lottery risk creeps in.

Judging: Be Transparent And Consistent

If you’re judging entries, you should spell out:

• the judging criteria (e.g. creativity, originality, relevance)
• who the judges are (or at least their role, such as “internal panel”)
• how ties are handled
• any public voting mechanics (and how you’ll prevent manipulation)

This is also where well-drafted terms matter – because if someone challenges the result, you want to be able to show that you followed the published process.

If your campaign involves partnering with another brand or sponsor (for example, they contribute the cash prize in exchange for exposure), you’ll usually want a Sponsorship Agreement to lock in who pays for what, how the prize is delivered, and who is responsible for compliance and claims.

When A Money Competition Becomes A Lottery (And What To Do Instead)

A lot of “money competitions” online accidentally drift into lottery territory, especially when entry is paid and the winner is chosen by chance.

As a general rule, if your promotion includes:

• Payment to enter (entry fee, subscription, paid ticket), and
• Chance determines the winner (random draw), and
• A prize (cash, gift cards, high-value items)

…you should treat it as a major red flag and get advice before launching.

What Are Your Safer Options?

Depending on your business model and goals, you may be able to restructure your promotion into a lawful format, such as:

• A genuine free prize draw (no paid entry requirement, with a clear and accessible free entry route).
• A genuine skill-based competition (with meaningful skill and a proper judging process).
• A properly run raffle/lottery where the right permissions and compliance steps are in place (this is not “casual marketing” territory).

If your promotion is closer to a raffle or lottery concept, it’s worth reading up on the specific compliance expectations around fundraising and prize mechanics before you advertise anything publicly. In many cases, it’s safer to pivot into a free prize draw or skill competition for marketing purposes.

For a broader setup perspective, the legal planning for these promotions is similar to starting a promotions-led business model, and the right contracts and processes really do make a difference. This is the sort of thing covered in a Competition Business setup.

Key Legal Compliance Areas: Advertising, Consumer Protection, And Data Privacy

Even if your competition structure is sound (prize draw vs skill contest), you still need to run it in a way that complies with broader UK laws and advertising standards.

1) Advertising Rules: Don’t Overpromise And Don’t Hide The Catch

Your marketing should match your terms. If you advertise “Win £1,000 today”, but the terms say the winner is drawn next month and must meet extra conditions, you’re setting yourself up for complaints.

In the UK, advertising for promotions is commonly assessed against the CAP Code (enforced by the ASA). As a small business, your safest approach is:

• make key conditions obvious (closing date, eligibility, entry caps)
• avoid misleading “guaranteed winner” style messaging
• don’t change the rules mid-promotion unless your terms clearly allow it and you do it fairly

2) Consumer Law: Fair Terms And Clear Prize Delivery

While competitions aren’t the same as selling goods, consumer protection principles still matter because you’re advertising to the public and making representations about the prize. In particular, unclear or unfair promotional terms can create risk under UK consumer protection rules.

Reduce risk by being very clear about:

• what the prize is (cash amount, whether alternatives exist)
• how and when it will be delivered
• any limitations (e.g. “paid in instalments”, “subject to identity checks”)

If you’re also using the competition to drive sales (for example, “buy X and you’re entered”), make sure your usual sales terms remain compliant too.

3) UK GDPR And Data Protection: Be Careful With Entries And Marketing Lists

Most competitions to win money involve collecting personal data, such as names, emails, phone numbers, shipping addresses, or social handles.

That means you need to think about:

• lawful basis for collecting and using the data
• privacy notices and transparency (what you’ll do with the data)
• marketing consent (you usually can’t bundle consent into entry without care)
• data retention (don’t keep it forever “just in case”)
• security (especially if you’re handling ID checks or payment data)

If you’re collecting entries via your website, you’ll normally want a proper Privacy Policy that aligns with how your entry forms, mailing list tools, and analytics actually work.

And if you’re using third-party tools (email marketing platforms, competition widgets, CRM systems) that process entrant data on your behalf, you may also need a Data Processing Agreement in place to help you comply with UK GDPR.

What Legal Documents And Practical Steps Should You Put In Place Before Launch?

When you’re excited to launch a new campaign, it’s tempting to focus on the creative and growth side first. But the legal setup is what protects your business if something goes wrong (for example, a dispute about eligibility, a platform takedown, or complaints that the promotion wasn’t run fairly).

A Simple Pre-Launch Checklist For Money Competitions

Before you launch your competition, it’s sensible to check:

• Category: Is it a free prize draw, skill-based competition, or something closer to a lottery under the Gambling Act 2005?
• Entry mechanics: Is entry genuinely free if it needs to be? If it’s skill-based, is skill meaningful?
• Terms: Are your rules clear, complete, and actually followed operationally?
• Platform rules: If you’re running it on social media, do you comply with that platform’s promotion policies?
• Data compliance: Do your entry form, privacy messaging, and marketing consent wording align with UK GDPR?
• Fulfilment: Are you ready to pay/deliver the prize on time, and do you have a process for verifying the winner?

Common Documents Businesses Use

Depending on how your promotion is structured, you may need:

• Competition terms and conditions (your core rules)
• Website terms (if entry is via your website)
• Privacy policy and entry-form privacy wording
• Sponsor/partner agreement (if someone else is funding or co-promoting)
• Creator/content permissions if entrants submit photos/videos you want to repost

If your competition involves user-generated content (UGC) and you plan to republish entries in ads or on your website, you may want entrants to agree to content permissions within the rules. In some situations (especially where identifiable people appear in content), a separate Model Release Form can be a practical way to document consent for promotional use.

And if your business model is specifically based around running promotional campaigns (rather than just occasional giveaways), you’ll want to structure it properly from the outset. For example, many businesses focus on Free-To-Enter Competitions because the compliance pathway is often clearer than paid-entry mechanics.

Key Takeaways

• Competitions to win money can be a powerful marketing tool, but you need to structure them carefully so they don’t become an unlawful lottery.
• Most small businesses will run either a free prize draw (chance + genuinely free entry) or a skill-based competition (winner determined by genuine skill/judgement).
• If your promotion includes payment + chance + prize, get legal advice before launch – that combination can trigger lottery rules and regulatory risk.
• Your terms should clearly cover eligibility, entry rules, how winners are selected, prize delivery timing, and what happens if the winner can’t be contacted.
• Don’t forget the wider compliance picture: advertising must not mislead (including under the CAP Code), and if you’re collecting entrant data, you need to comply with UK GDPR (including clear privacy information and careful marketing consent wording).
• Getting the right documents in place upfront (competition terms, privacy policy, sponsor agreements, content permissions) helps protect your business and keeps your promotion running smoothly.
