Summary
A lottery under the Gambling Act 2005 requires two things: entrants pay, and prizes are allocated wholly by chance. Remove either and it stops being a lottery and stops needing a licence. Car competition operators remove the chance element with a skill question, or remove the payment element with a genuine free entry route. Both are lawful, both are common, and a company can use either. What isn't lawful is charging for a purely random draw without a licence, which is a criminal offence. Prize competitions and free draws also sit outside Gambling Commission regulation, which is a separate issue from legality.
The short answer
Legitimate UK car competitions are legal. They aren't operating in a grey area, exploiting a loophole, or waiting to be shut down. They're built to a specific statutory shape, and when they hold that shape they sit outside gambling law altogether.
The reason this is worth understanding rather than just accepting is that everything entrants find strange about the format — the trivia question before checkout, the postal entry buried in the terms — exists solely to satisfy the law. Once you know what the law requires, you can tell at a glance whether a site is complying with it.
What the law actually says
The Gambling Act 2005 governs gambling in Great Britain, and it defines a lottery narrowly. Two conditions have to be met together:
Entrants are required to pay to participate, and
Prizes are allocated by a process that relies wholly on chance.
Both limbs must be present. Satisfy both and you are running a lottery, which requires a licence and, in Great Britain, can only be run for good causes — society lotteries, local authority lotteries and the National Lottery. A private company cannot lawfully run a lottery to make a profit, however professionally it does it.
That's the constraint. A commercial operator selling tickets for a car has to break one of those two limbs, and there are two ways to do it.
Route one: the skill question
Break the chance limb.
The Act treats a process as relying wholly on chance unless it requires entrants to exercise skill or judgement, or to display knowledge, to a meaningful degree. The statutory test is about effect rather than intention: the requirement has to be one that can reasonably be expected either to deter a significant proportion of people who want to enter from doing so, or to prevent a significant proportion of those who do enter from winning a prize.
That's why the question exists, and why it has to have consequences. A wrong answer must actually eliminate the entry — if everyone gets through regardless, the question isn't doing the work the Act requires and the competition is a lottery in substance whatever the terms say.
In practice most operators pitch their questions at the easy end. This has drawn sustained criticism, and it's the part of the model most likely to change if the sector is regulated more tightly. Whether a given question meets the statutory test is a question of fact that would ultimately be decided by a court, not something an operator can settle by asserting it in its terms.
Route two: the free entry route
Break the payment limb.
If there is a genuinely free way to enter, the competition isn't one where entrants are required to pay, so it falls outside the lottery definition as a free prize draw. This route is set out in Schedule 2 of the Act, and the conditions are strict.
The free method must give the same chance of winning as a paid entry. It must be adequately communicated rather than hidden in small print. It must not be materially more inconvenient than paying, beyond the ordinary cost and effort of posting something. And the system must not be designed to put free entrants at a disadvantage.
This is why postal entry exists on sites that otherwise look purely commercial. It is not a courtesy and it is not marketing. On a site relying on this route, the postal option is the thing keeping the whole operation lawful, and an operator who quietly obstructs it undermines its own legal position.
Plenty of operators run both routes at once — a skill question and a free postal entry — which is belt and braces rather than a requirement.
Route three: an actual lottery licence
The third option is to be a lottery properly. Charity and society lotteries offering car prizes are licensed by the Gambling Commission, registered with a local authority, or both, depending on size. These are regulated gambling products, with the compliance obligations that brings, and proceeds must go to the good cause behind them.
This is a minority of car prize draws but not a rare one, particularly where a charity is the promoter.
Who regulates them
This is where legality and oversight come apart, and it's the point most commonly misunderstood.
The Gambling Commission regulates lotteries. It does not license or supervise prize competitions or free draws, because by design those aren't gambling. It publishes guidance on where the boundary sits and can act where it believes a promotion has crossed it into an unlicensed lottery — but it does not audit draws, vet operators, or handle disputes about whether you received your prize.
Other law still applies. The CAP Code, enforced by the Advertising Standards Authority, governs how promotions are advertised and requires that prizes be awarded as described and closing dates honoured. The Consumer Protection from Unfair Trading Regulations 2008 prohibit creating a false impression that someone has won a prize, and other misleading practices. The Consumer Rights Act 2015 governs unfair contract terms, which is relevant to the more aggressive clauses in some competition terms.
So the sector isn't lawless. It is unlicensed, which is a different thing, and it means no regulator is routinely checking that a given draw was fair.
Northern Ireland and Ireland
The Gambling Act 2005 applies to Great Britain. Northern Ireland has its own framework, principally the Betting, Gaming, Lotteries and Amusements (Northern Ireland) Order 1985, which treats these matters differently. This is why some operators restrict entry to Great Britain rather than the UK as a whole.
The Republic of Ireland is a separate jurisdiction with its own gaming and lotteries legislation. UK operators accepting ROI entrants are dealing with a second regime, and many choose not to.
When a car competition is illegal
The clear case: entrants pay, the winner is drawn at random, there is no skill requirement and no free entry route, and the promoter holds no licence. That is an unlicensed lottery, and promoting one is a criminal offence under the Gambling Act carrying a potential prison sentence and an unlimited fine.
In practice this describes informal draws more often than established sites — social media giveaways where someone collects payments and picks a name, "raffles" run for a private car sale, and small operations that copied the format without understanding why it exists. The tells are the absence of any question at checkout, no mention of postal entry anywhere in the terms, and no company details.
Worth being clear: the offence is committed by the promoter, not by entrants. Nobody who bought a ticket in an unlicensed draw has broken the law. The risk to you is commercial rather than legal — an operator willing to ignore gambling legislation is not one you want holding your money or your prize.
Is the law changing?
Possibly. The structural point that a large, professionalised industry operates outside gambling regulation because of how its products are drafted has been raised repeatedly, including in government-commissioned work looking at whether prize competitions should be brought within the Gambling Commission's remit.
Nothing has changed the position at the time of writing. If it does, the likely direction is licensing requirements for larger operators and stricter tests on what counts as a genuine skill question, rather than prohibition.
This guide explains how the law is structured; it isn't legal advice, and anyone with a specific dispute should take proper advice on their own circumstances.
FAQs
Are car competitions legal in the UK? Yes, when they include a genuine skill question or a genuine free entry route, or when they operate under a lottery licence. Those structures keep them outside the Gambling Act's definition of a lottery.
Are car competitions gambling? Legally, no. Because entrants either aren't required to pay or aren't winning purely by chance, they fall outside the statutory definition of gambling and don't require a gambling licence.
Why do car competitions ask a skill question? To remove the element of pure chance. The Gambling Act treats a draw as chance-based unless the skill requirement can reasonably be expected to deter a significant proportion of would-be entrants or eliminate a significant proportion of those who enter.
Does the free postal entry have to be genuine? Yes. It must offer the same chance of winning as a paid entry, be properly communicated, and not be made deliberately inconvenient. An obstructed free route puts the promoter's legal position at risk.
Who regulates UK car competitions? No single regulator. The Gambling Commission covers lotteries only. Advertising falls to the ASA under the CAP Code, and consumer protection law applies through Trading Standards. Prize competitions themselves are unlicensed.
Is it illegal to run a car raffle without a licence? If entrants pay, the winner is picked purely at random, and there's no free entry route, then yes — that's an unlicensed lottery and a criminal offence under the Gambling Act 2005.
Have I broken the law by entering an unlicensed draw? No. The offence sits with the promoter. Your exposure is practical rather than legal: an operator ignoring gambling law is a poor bet to deliver a prize.
Do the same rules apply across the whole UK? Not quite. The Gambling Act 2005 covers Great Britain. Northern Ireland operates under its own 1985 Order, which is why some competitions exclude NI entrants.
