The business model looks simple from the outside. Sell entries, run a draw, deliver a prize, repeat. Low overheads, no inventory to speak of, and a product that markets itself if the prize is good enough.
Plenty of UK founders have built real companies this way. Plenty of others have got three months in, spent money on advertising, and discovered that the thing standing between them and growth is not demand or product. It is a piece of documentation they had never heard of when they started.
The line you are standing on
UK law treats lotteries and prize competitions differently. A lottery requires a licence from the Gambling Commission. A genuine prize competition does not, provided it meets specific conditions set out in the Gambling Act 2005.
The distinction turns on whether skill, knowledge or judgement plays a sufficient role in determining the outcome, or whether a free entry route is offered that is genuinely equivalent to the paid one. Most operators rely on one or both.
The difficulty is that “sufficient” and “genuinely equivalent” are legal tests, not checkboxes. A quiz question that anyone can answer by searching may not do the work the operator assumes it does. A free entry route buried in the terms and requiring a posted letter may not be equivalent in the way the legislation intends.
Founders rarely get this wrong deliberately. They get it wrong because they copied the structure from a competitor who may also have got it wrong.
Where it actually bites
You can operate for a while without resolving this. What you generally cannot do is advertise at scale.
Meta, Google and the major advertising platforms apply their own policies to this category, and those policies are stricter than the law. A business can be entirely lawful and still find its ad account restricted, because the platform is not assessing legality. It is assessing whether you have provided the documentation its review process requires.
For a competition business, paid social is usually the primary acquisition channel. An account restriction is therefore not a compliance inconvenience. It is the revenue stopping.
This is the point at which most founders encounter the subject, and it is the worst possible moment: under time pressure, with spend already committed, and with a prize to fulfil regardless.
What the documentation involves
The common route is a legal opinion from a solicitor with gambling law experience, confirming that the specific mechanics of your competition fall outside the definition of a lottery. It assesses your actual question format, your actual free entry route and your actual terms, rather than the category in general.
Operators who need this for advertising approval generally pursue it through a specialist, and agencies working in the sector often coordinate it alongside the platform work. Nera Marketing’s guidance on the prize competition RMG licence process covers what the advertising platforms ask for and how the documentation is usually assembled.
The output is a document you can submit, and the practical value is that it converts an ambiguous position into something a reviewer can accept.
Four things to get right before you spend on ads
Design the skill element properly. If you are relying on a question, it needs to do real work. Get the format reviewed rather than copying what you have seen elsewhere.
Make the free entry route genuine. If you offer one, it should be reasonably accessible and clearly presented, not technically present and practically useless.
Write terms that match what you actually do. Terms copied from another operator will describe their mechanics, not yours, and the mismatch is visible to anyone who looks.
Keep records of each draw. Timestamped, immutable, and sufficient to demonstrate the process ran as described. You will want these if a customer complains, and you will certainly want them if a regulator asks.
The sequencing most founders get backwards
The instinct is to build the site, launch, prove the model, then deal with the legal position once there is revenue to justify it.
The sequence that works is the reverse. Establish the position first, get the documentation, then build and advertise against something settled. It feels slower and it costs money before you have made any, but it avoids the scenario where you have customers, a prize obligation and no way to acquire the entries you need to cover it.
The Advertising Standards Authority also publishes guidance on how promotions must be presented, which is worth reading at the same time, since the two sets of requirements overlap.
The takeaway
Prize competitions are a legitimate UK business model with a well-trodden legal path. The founders who struggle are not usually the ones doing something wrong. They are the ones who left the paperwork until the advertising platform forced the issue.
If you are planning to launch in this category, treat the legal position as part of the build rather than as something to resolve afterwards. It is cheaper, faster and considerably less stressful than discovering it the other way round.
