The basic idea
Strip it back and a car competition is simple. An operator puts up a prize — anything from a used Fiesta to a new Lamborghini — and sells a fixed number of tickets. Each ticket gets a number. When the tickets sell out, or the closing date arrives, a number is drawn and whoever holds it wins the car.
What makes it different from a raffle is the bit in the middle. Before you can buy a ticket you have to answer a question. That question is the reason the whole industry exists in its current form, so it's worth understanding properly.
Why the skill question matters
Under the Gambling Act 2005, running a lottery in Great Britain requires a licence, and lotteries can only be run for good causes. A company giving away a Porsche for profit can't be a lottery.
The Act carves out an exemption for "prize competitions" — as long as winning depends on skill, knowledge or judgement, it isn't gambling. The test is that the question has to be hard enough to either stop a significant proportion of people from entering, or stop a significant proportion of entrants from getting it right.
In practice, most sites lean towards the easy end of that spectrum. You'll see questions like "which of these is a British car manufacturer?" or a bit of mental arithmetic. Get it right and your ticket goes into the draw; get it wrong and, on most sites, you've still paid but your entry is void. Some operators let you retry, others don't, so it pays to check the terms before you click confirm.
This is the part most people find odd the first time. It feels like a formality — and honestly, it often is — but it's a formality with legal weight behind it. Operators take it seriously because getting it wrong means they're running an illegal lottery.
How tickets and odds work
Every competition has a maximum number of tickets. That number is your odds, and it's the single most important thing on the page.
If a car has 5,000 tickets and you buy one, you have a 1 in 5,000 chance. Buy ten and it's 1 in 500. Operators often show a "sold" percentage or a progress bar, which tells you both how close the draw is and how many tickets are actually in play.
A few things to watch here:
Ticket limits. Most sites cap how many tickets one person can buy per competition — sometimes 10, sometimes several hundred. A low cap keeps the draw fairer for everyone; a very high cap means a few people can buy up most of the odds.
Price versus ticket count. A £1 ticket in a 100,000-ticket draw is a different proposition from a £5 ticket in a 2,000-ticket draw. Work out the total ticket value and compare it with the car's real market value — it tells you a lot about the operator's margin and how much they're relying on selling out.
Guaranteed draws. Some competitions draw regardless of how many tickets sell. Others only draw once every ticket is gone, and extend the closing date if they haven't. Guaranteed draws are better for you as an entrant; extended ones can drag on for months.
What happens on draw day
Most reputable UK operators now draw live, usually on Facebook or YouTube, and often at a fixed time so regulars know when to tune in. The common method is a random number generator — Google's built-in one or a site like Random.org — with the winning number matched to a ticket on screen.
A handful of bigger operators use third-party draw services or have the process independently observed. That's not a legal requirement, but it's a strong trust signal and we weight it heavily in our reviews.
If you've entered, you don't need to be watching. Winners are contacted by phone or email, and most sites publish a winners list with a photo of the handover. That list is worth reading before you enter anywhere — a long, dated, verifiable winners page is one of the clearest signs a site is genuine.
When you win: cash, delivery and paperwork
Winning a car isn't quite as simple as being handed the keys, though it's not far off.
Cash alternative. Nearly every competition offers a cash option instead of the car, usually somewhere between 60% and 80% of the listed value. Some people prefer this — it avoids insurance, tax on the vehicle, and the awkwardness of a supercar on a terraced street. The exact figure is always in the T&Cs, so look before you enter rather than after you've won.
Delivery and handover. The operator typically arranges delivery or a collection date, and most film it for their winners page. You'll need to sort insurance before you drive it away.
Paperwork. The V5C logbook is transferred into your name like any private sale. The operator should handle their side; you just need to confirm the details.
Tax. Competition prizes aren't taxed as income in the UK. You won't owe HMRC anything on the win itself, though you'll pay the usual road tax and insurance once the car is yours.
The free entry route
Because the competition has to stay within the prize-competition exemption, most operators also offer a free way in — usually by post. You send a postcard with your details and the answer to the skill question, and you get a ticket in the draw without paying.
It's real, it's legal, and it does work. The catch is that it's slow, most sites limit you to one free entry per competition, and the postcard has to arrive before the closing date. We've written a separate guide to the free entry route, including how to word the entry and which sites make it easier than others.
How to tell a good operator from a bad one
The industry has grown fast and not every site is run well. Things we check before recommending any operator:
A registered UK company with a searchable Companies House entry.
Clear T&Cs covering the draw method, cash alternative, ticket limits and what happens if a competition doesn't sell out.
A winners page with dates, names and photos going back more than a few months.
Live draws that are recorded and stay available afterwards.
Reviews on Trustpilot or similar that mention actual wins, not just a smooth checkout.
If a site fails two or more of those, walk away. There's no shortage of good ones.
Frequently asked questions
Are car competitions legal in the UK? Yes, provided they're structured as prize competitions with a genuine skill element, or offer a free entry route. That's what keeps them outside the licensing requirements of the Gambling Act 2005. Sites that sell tickets with no question and no free route are running an unlicensed lottery, which is illegal.
Do I have to pay tax if I win a car? No. Prize winnings aren't treated as income by HMRC, so there's nothing to declare. You'll pay road tax and insurance as normal once it's registered to you.
What are the odds of winning? Whatever the ticket count says. One ticket in a 10,000-ticket draw is a 1 in 10,000 chance. Every additional ticket you buy improves your odds in direct proportion, up to the site's per-person limit.
Can I get my money back if I get the skill question wrong? Usually not. Most operators treat a wrong answer as a void entry and keep the fee. Some allow a retry before payment, so read the entry page carefully.
What happens if the competition doesn't sell out? It depends on the site. Some draw anyway on the closing date ("guaranteed draw"). Others extend the closing date until all tickets are sold, and a few reserve the right to substitute the prize for a cash amount based on tickets sold. The T&Cs will state which applies.
Is a car competition the same as a car raffle? People use the terms interchangeably, but legally they're different. A raffle is a form of lottery and needs a licence; a car competition avoids that by adding a skill question or free entry route. When a UK site calls itself a "car raffle", it's almost always running a prize competition and just using the more familiar word.
Can I enter for free? Yes, on most sites, via a postal entry. See the free entry route section above and our dedicated guide for the details.
How do I know a competition site is legitimate? Check for a UK company registration, detailed terms, a verifiable winners list, recorded live draws and independent reviews. Our site reviews cover each operator against exactly those criteria.
