Are TikTok Giveaways Legal in the UK? ASA and CAP Code Explained

If you search "are TikTok giveaways legal in the UK," the short answer is yes. A free-to-enter prize draw is not an illegal lottery under UK law, and you do not need a licence, a bond, or a registration number to run one, whatever the prize is worth. That part is genuinely simple.

What trips people up is assuming legal is the whole story. It is not. Running a giveaway in the UK actually means clearing two separate hurdles, and they come from two completely different bodies of law. The first is whether your promotion counts as an illegal lottery under the Gambling Act 2005. The second, and the one almost nobody checks, is whether the way you run and advertise it complies with the CAP Code, enforced by the Advertising Standards Authority. Miss the first and you have a criminal law problem. Miss the second and you get a public ASA ruling with your brand's name on it, which is its own kind of damage on a platform built on trust.

This guide walks through both, in plain terms, so you can run a TikTok giveaway that is not just technically legal but actually holds up if someone complains.

Question one: is it an illegal lottery?

UK gambling law draws a bright line around three ingredients: a prize, an element of chance, and a payment to enter. Put all three together without an exemption and you have run an illegal lottery under the Gambling Act 2005, which only the National Lottery, licensed society lotteries, and a handful of other regulated operators are allowed to do.

The good news for almost every TikTok giveaway is that free entry removes the third ingredient entirely. If nobody has to pay anything, buy anything, or spend money to enter, there is no lottery to worry about, and the Gambling Commission has no interest in it. A creator asking people to comment a word under a video, at zero cost, is operating completely outside gambling regulation. This is why a free TikTok giveaway needs no licence and no registration, unlike the state-by-state registration and bonding rules that apply to larger sweepstakes in the United States. The UK simply has no equivalent system for a properly free draw.

One regional wrinkle worth knowing: Northern Ireland runs on its own legislation, the Betting, Gaming, Lotteries and Amusements (Northern Ireland) Order 1985, rather than the Gambling Act 2005 that covers England, Scotland, and Wales. The practical effect for a free giveaway is small, since the same free-entry logic keeps you outside regulated gambling there too, but it is worth knowing the two nations are not governed by the identical statute if you ever need to check a detail closely.

Where it goes wrong: mixing payment into the entry

The lottery question only gets interesting when payment sneaks into the mechanic. This usually happens by accident rather than design. A brand wants engagement and real intent from entrants, so it asks people to buy a product, tag the purchase, and enter that way. The moment a purchase becomes the only route to entry, chance plus prize plus payment are all present, and you have built an illegal lottery.

UK law has a specific, well-established fix for this called the free entry route. Under Schedule 2 of the Gambling Act 2005, you can still ask for a purchase as one entry path, as long as you also offer a genuinely free alternative that gives entrants exactly equal odds. That means the free route has to be promoted with the same prominence as the paid one, cannot require anything more onerous than a stamp or a postcard-equivalent effort, and cannot put free entrants at any disadvantage in the draw. Bury the free option in small print at the bottom of a caption while pushing the paid entry front and centre, and regulators will treat that as a lottery in substance even if you technically offered an alternative. If your giveaway design leans on a purchase requirement at all, building in a real, equally promoted free route is not optional, it is the difference between a promotion and a criminal offence.

Question two: are you running it fairly?

Once you have cleared the lottery question, most creators assume they are done. This is the assumption that gets people an ASA ruling. Free-to-enter prize draws sit outside gambling law, but they sit squarely inside advertising law, specifically Section 8 of the CAP Code, the UK Code of Non-broadcast Advertising, Sales Promotion and Direct Marketing.

The ASA has been explicit that this is not a loophole for social media. Its own published guidance on prize draws in social media states that Section 8 rules apply wherever a promotion appears and whoever runs it, whether that is a brand or an influencer running the promotion on their own platform, or brands and influencers working together as joint promoters. TikTok is not a grey area here. A creator running a comment-to-win giveaway on their own account is, in the ASA's own framing, doing the same thing as a national brand running a printed competition, just on a different platform.

The specific CAP Code rules that catch people out

Section 8 has more than thirty individual rules, but a handful account for almost every complaint the ASA actually upholds against giveaways.

Rule 8.17 requires that significant conditions be stated in your initial marketing material, not tucked away somewhere an entrant only finds after they have already entered. If there is a minimum age, a geographic restriction, a closing date, or a limit on entries per person, that has to be visible in the video or caption people see first, not buried three comments deep in a reply thread.

Rule 8.20 says you cannot exaggerate the odds of winning or imply a better chance of success than actually exists. Language that suggests entering is a near-certain win, or that downplays how many people are competing for the prize, falls foul of this even if it was meant as harmless hype.

Rule 8.21.1 is a simple one: it must cost nothing to claim a prize. If a winner has to pay postage, a processing fee, or any other charge to actually receive what they won, that breaches the code regardless of how the entry itself was structured.

Rule 8.23 restricts changing the conditions of entry once a promotion is live, allowing it only in exceptional circumstances. Quietly changing the rules partway through, extending a deadline because engagement was low, or narrowing eligibility after the fact, is exactly the kind of thing that draws a complaint from someone who feels the goalposts moved.

Rules 8.24 and 8.26 require that winners be selected by a method that genuinely relies on chance, applied equally to all eligible entrants. If you use a computer-based process, which almost every comment-based TikTok giveaway does, the ASA's expectation is that you can produce evidence of how that randomness actually works if a complaint is ever raised. This is precisely why the method behind a comment picker matters and is not just a technical detail. A tool built on a cryptographically secure random number generator, the kind covered in this breakdown of how comment pickers actually work, gives you something concrete to point to. A hand-picked "closed my eyes and scrolled" winner gives you nothing to show if someone asks.

Beyond those, the code also expects you to be ready to publish basic winner information, typically a surname and county or similar, provide the actual winning entry to the ASA if requested, and offer a reasonable equivalent prize if the advertised one becomes genuinely unavailable. None of this is exotic. It is the same standard that has applied to prize draws in magazines and on television for decades, simply extended to TikTok because that is where promotions happen now.

The influencer-specific wrinkle: scale creates responsibility

There is a nuance in ASA enforcement that catches larger creators off guard. In one real case, the ASA scrutinised a prize draw run by an influencer with more than five million followers offering an £8,000 prize, and part of its consideration was whether someone with that reach should reasonably have anticipated the volume of responses their promotion would generate, and planned their process accordingly.

The practical takeaway is that your obligations do not shrink because you are an individual creator rather than a corporate brand, and they can effectively grow with your following. A promotion that would be manageable and low-risk for a ten-thousand-follower account can generate a flood of entries for a five-million-follower one, and the ASA has shown it expects that scale to be planned for, not used as an excuse afterward.

What if you're a small, non-commercial creator?

The CAP Code's remit generally covers marketing communications, which raises a genuine question for a very small creator running an occasional, informal giveaway with no brand deal or commercial arrangement attached. In practice, the ASA's own guidance leans toward its rules applying broadly to prize draws run on social media regardless of scale, precisely because it has stated the rules apply "whoever" runs them.

The safer assumption, and the one that costs you nothing to follow, is to treat every giveaway as if Section 8 applies, no matter how small your account is. State the rules clearly, use a genuinely random selection method, do not charge for prize claims, and be ready to show your work if anyone asks. If your promotion is small enough that a complaint is unlikely, none of this is wasted effort. If it grows faster than expected, which is exactly the kind of thing that happens on TikTok, you are already covered.

How this differs from what you might have read about US giveaways

If you have also researched US giveaway law, the frameworks can blur together, so it is worth being precise about where they diverge. The US test for an illegal lottery is prize, chance, and consideration, essentially the same three-part structure as the UK's, but the US layers a patchwork of state-specific rules on top, including registration and bonding requirements once a prize crosses certain value thresholds in states like New York and Florida, as covered in the earlier guide on whether TikTok giveaways are legal under US rules.

The UK has nothing equivalent to that state-by-state registration system. A properly structured free UK prize draw needs no licence and no bond regardless of the prize's value, full stop. What the UK has instead, and what US giveaway law does not have a direct parallel to, is the CAP Code and active ASA enforcement of exactly how a promotion is run and advertised. So the compliance burden does not disappear in the UK, it just moves from a legal registration question to an advertising standards question, and it is enforced by a completely different body using a completely different rulebook.

It is also worth being clear that a prize draw is not automatically the same thing as a raffle or a skill-based contest, which carry their own separate rules again. The distinction actually matters for how you set entry conditions and select a winner, and the breakdown of the difference between a raffle and a giveaway on TikTok is worth reading if your promotion involves anything beyond a straightforward free comment-to-enter mechanic.

A practical UK compliance checklist

Before you post a giveaway aimed at a UK audience, run through this list.

Confirm entry is genuinely free, or that a truly equal, equally promoted free alternative exists if there is any purchase-linked entry path.

State the significant conditions, age restrictions, geographic limits, closing date, one entry per person, in the video or caption itself, not hidden in a reply.

Do not exaggerate the odds of winning or suggest entering guarantees anything.

Make sure claiming the prize costs the winner nothing at all.

Set your entry conditions before you launch and avoid changing them once the giveaway is live.

Use a genuinely random selection method and keep a record of it. A published set of official giveaway rules covering these points, generated before you launch, gives you something concrete to point to if anyone questions how the draw was run.

Be ready to publish basic winner details and to produce the winning entry if the ASA or a complainant asks.

Have a genuinely equivalent backup prize ready in case the advertised one becomes unavailable.

A free TikTok giveaway in the UK is legal from the moment you remove payment from the entry, and it stays that way with almost no ongoing effort. What takes deliberate work is the second half, running it the way the CAP Code and the ASA actually expect, with clear conditions, honest odds, a genuinely random draw, and a process you could defend if someone complained. Get both halves right and a UK giveaway is one of the lowest-risk promotions you can run on TikTok, prize draws have operated under this exact framework for decades, and TikTok did not change the underlying law, only the platform it plays out on.
