In short
Pick a competition on a legitimate UK site, buy a ticket (usually £1–£5), answer a multiple-choice skill question, and you're in the draw. That's it. Most sites take a couple of minutes from landing on the page to confirmation.
The bits worth slowing down for: check how many tickets there are (that's your odds), check the cash alternative, and check whether the draw is guaranteed or only happens once every ticket sells. Set a budget before you start, because tickets are cheap and it's easy to buy more than you meant to.
Nearly every site also has a free postal entry route. It's slower, but it's real.
Step 1: Pick a legitimate site
Before you look at a single car, look at who's running the competition. The UK market has a handful of large, well-established operators and a long tail of smaller ones, some excellent, some not.
The quick checks:
Is it a registered UK company? The name and number should be in the footer or T&Cs. Search it on Companies House.
Is there a winners page with photos and dates? A long, verifiable history is the strongest single trust signal.
Are draws done live and recorded? Look for a Facebook or YouTube link. Old draws should still be viewable.
Do the reviews mention actual wins? Trustpilot reviews that only praise the checkout process aren't much use.
We've done this for every operator we list — our site reviews cover each one against the same criteria — so if a site is on our recommended list, it's passed these checks.
Step 2: Understand the listing
Every competition page tells you the same handful of things, and they matter more than the photo of the car.
Ticket price. Usually £1 to £5 for a car, sometimes more for high-end prizes. Some sites discount bulk purchases.
Total tickets. This is your odds. 1 ticket in 5,000 is a 1 in 5,000 chance. The number is on the page, often with a progress bar showing how many are sold.
Ticket limit per person. Most sites cap this. A low cap (10–50) means the draw can't be dominated by one buyer. A very high cap means it can.
Closing date and draw date. The draw is usually the day after closing, at a fixed time. If the competition is "guaranteed", the draw happens on that date regardless of sales. If it isn't, the date may be pushed back until tickets sell out.
Cash alternative. The lump sum you can take instead of the car. Typically 60–80% of the car's value. We've written a separate guide on this.
The T&Cs link. Skim it. Specifically look for what happens if the competition doesn't sell out, and whether the prize can be substituted.
Step 3: Buy your tickets
Add the number of tickets you want and go to checkout. Most sites let you pick specific ticket numbers or have them assigned randomly — it makes no difference to your odds, but some people like choosing.
Payment is by card on almost every site. A few accept PayPal or Apple Pay. Credit cards are generally accepted, though a small number of operators are card-only or debit-only, so check if it matters to you.
On budget: decide before you start how much you're comfortable spending across a month, not per competition. The individual tickets are cheap enough that the total creeps up quickly, and buying more tickets in a draw you've already entered feels like "improving your odds" when really it's just spending more. Ten tickets in one competition is a 1 in 500 chance if there are 5,000 tickets. That's still a long shot.
Step 4: Answer the skill question
Before payment goes through, you'll be asked a question. This is the legal mechanism that keeps the competition on the right side of the Gambling Act — it has to involve some skill or knowledge so it isn't a lottery.
In practice the questions are usually straightforward: which of these is a British car brand, what's 12 multiplied by 4, what colour is the car pictured. Read it properly. On most sites a wrong answer voids your entry and you don't get the money back. Some sites let you retry before confirming payment; some don't.
If you're unsure, don't guess. It's fine to check the answer first — that's the "skill" part.
Step 5: Confirmation and what happens next
You'll get an email with your ticket number(s) and the draw date. Keep it. Most sites also show your entries in an account area.
You don't need to watch the draw. Winners are contacted directly by phone or email, and the result is posted on the operator's winners page and social media afterwards. If you want to watch, live draws are usually on Facebook or YouTube at the advertised time.
If you win, you'll be asked to choose between the car and the cash alternative, usually within a few days. Have a rough idea what you'd do before that call comes.
Entering for free by post
Because these competitions rely on the prize-competition exemption in the Gambling Act, most operators offer a free entry route — almost always by post.
You write your name, address, email and the answer to the skill question on a postcard or letter, and send it to the address in the T&Cs. It goes into the draw exactly like a paid ticket. It's genuinely free apart from the stamp.
The catches: it's usually limited to one free entry per competition, the postcard has to arrive before the closing date, and some operators are stricter about the format than others. We've written a full guide to the free entry route with a template and site-by-site notes.
Common mistakes first-time entrants make
Only looking at the car. The ticket count and cash alternative matter far more than the photo.
Not reading the substitution clause. Some non-guaranteed draws pay a much smaller cash sum if they don't sell out.
Chasing a draw. Buying more tickets in a competition you've already entered because it's "nearly sold out" is a budget trap.
Guessing the skill question. A wrong answer usually costs you the entry.
Using unfamiliar sites for big prizes. Start with established operators. Once you know what a well-run competition looks like, you'll spot the ones that aren't.
Ignoring the free route. One free entry per competition, across a dozen competitions a month, adds up.
A word on responsible entry
Car competitions are designed to be fun and low-cost, and for most people that's exactly what they are. But the mechanics — cheap tickets, near-miss feeling, regular draws — are the same ones that make other forms of chance-based spending hard to control for some people.
Set a monthly figure you'd be happy to lose entirely and stick to it. If you find yourself entering to recover money you've spent, or hiding how much you've spent, that's the point to stop. GamCare (0808 8020 133) is free and confidential, and many operators offer account limits or self-exclusion if you ask.
Frequently asked questions
How do I enter a car competition? Choose a competition on a UK operator's site, buy one or more tickets, answer the skill question correctly, and you're entered into the draw. You'll receive your ticket numbers by email.
How much does it cost to enter? Typically £1 to £5 per ticket for a car, sometimes more for high-value prizes. Most sites cap the number of tickets one person can buy.
Can I enter a car competition for free? Yes. Most UK operators offer a free postal entry route. Send your details and the skill question answer to the address in the T&Cs before the closing date.
Do I have to be in the UK to enter? Usually yes — most operators restrict entry to UK residents, and some to Great Britain only (excluding Northern Ireland). Check the terms.
How old do I have to be? 18 on almost every site. A few allow 16+, but it's rare.
What is the skill question? A short multiple-choice or simple knowledge question you must answer correctly for your entry to count. It's what legally separates a prize competition from a lottery.
What happens if I get the skill question wrong? On most sites your entry is void and you don't get a refund. Some allow a retry before payment. Check before you confirm.
How will I know if I've won? The operator will contact you directly by phone or email. Results are also published on their winners page and social channels after the live draw.
Can I buy tickets for someone else? Usually not directly — entries are tied to the account holder. Some sites offer gift vouchers. Check the terms.
