Win big prizes for pennies by using the free postal entry loophole—beat the odds and enter high-value competitions without paying ticket prices.

What Is Online Comping?

What if we told you there’s a way to enter competitions for  big prizes—without paying the high entry fees? That’s exactly what the  free postal route offers. And yes, it’s completely legal.

How Does It Work?

Many competition websites run what’s legally classified as a  lottery—and UK gambling law requires them to offer a  free entry route, usually by post.

Here’s how to do it:

  1. Find a competition you like (cash prizes, tech, holidays—you name it).

  2. Write your entry details on a postcard. This usually includes:

    • Full name

    • Address

    • Contact details

    • Correct answer to any skill-based question (some comps have these – they may only appear once you add the ticket to basket or log in).

  3. Full name

  4. Address

  5. Contact details

  6. Correct answer to any skill-based question (some comps have these – they may only appear once you add the ticket to basket or log in).

  7. Send it off with a  Second Class stamp (or first) —costing you around  £1 all in.

That’s it. You’ve just entered a competition that others might pay £1000s for—for the price of a stamp/postcard.

What Comps Should You Go For? 🎯

To maximise your chances, focus on:

✅  Low ticket numbers – the fewer tickets sold, the better your odds
✅  High-value prizes – £1 (postage cost) for a shot at £1,000+? Yes please
✅  Expensive paid entry prices – comps charging £20+ per ticket give you great value from the free entry route

💡  Example: One of our team recently sent a free entry for a £1,000 cash prize draw. Tickets were £20 each—and only  75 tickets were sold. That’s a  1 in 75 chance for roughly £1 in postage. (See photo!)

Top Tips for Success 📝

  • ✅ Always include every detail they ask for

  • ✅ Double-check for entry questions – these can be easy to miss until checkout

  • ✅ Post in good time – don’t risk missing the deadline

  • ✅ Stick with trustworthy competition providers – legally they must accept postal entries, but it’s best to focus on those who’ve regularly honoured yours

Final Word

You won’t win every time—but just like matched betting this is a numbers game. And the odds? They’re heavily stacked in your favour, especially when you target the right competitions.

Frequently asked questions

Is online comping really worth it?

Yes! Thanks to a surge in competition websites, it’s easier than ever to find high-value prizes. And with the free postal route, you can enter for as little as £1.

Do I need to be a certain age to take part?

Yes, you must be  18 or older to legally enter these competitions.

Why do competitions have to offer a free postal entry?

If a competition doesn’t offer a free entry route (usually by post), it’s classed as an  illegal lottery under UK law. Reputable sites follow this rule strictly.

How much does it cost to enter by post?
  • 2nd Class Stamp: 87p

  • 1st Class Stamp: £1.35
    Plus a postcard or envelope – so most entries cost around  £1 total.

Can I enter multiple times?

Yes, many comps allow  multiple postal entries. Just check the terms—each entry must be sent separately (with its own stamp and postcard). Be aware that if one entry is lost, others could be affected too.

Are winnings taxable?

No. Competition winnings are classed as  gambling income, which is  tax-free in the UK. No need to set up a business or declare it.

Got an example of the value?

Absolutely. Take a comp offering a  £20,000 car for  £100 per entry with just  300 tickets. If all are sold, the site earns £30,000—yet you can enter for under £1 via post. That’s a potential 1-in-300 chance for pennies.

What do I need to get started?
  • Black pen

  • Postcards or envelopes

  • Stamps

  • Internet access

  • A spare email account (to avoid spam)

  • Must be over 18

Any tips to speed things up?
  • Use autofill when signing up online

  • Keep apps for your favourite comp sites

  • Always read T&Cs carefully

  • Write neatly – don't give them a reason to disqualify your entry

  • Send entries in good time

  • Use  1st Class for tight deadlines or big prizes

  • Track all your entries

What mindset should I have?

See it as a hobby. Don’t obsess over live draws or expect regular wins.  Treat wins as a bonus, and understand you’ll lose some time and money along the way.

Are all competitions legitimate?

Stick to comps with  positive reviews (e.g. on TrustPilot). Legally, companies must accept postal entries—but in practice, entries may go missing or get rejected (e.g. due to errors, lost mail, or site oversight). If that happens, a polite follow-up message can help.

Any other ways to enter for free?

Some sites offer  free-to-play competitions or even phone-in entry options. These are often lower value or have more competition, but they’re still worth exploring.

Should I choose the prize or the cash alternative?

Always check the  cash value vs resale value. Sometimes it’s better to take the prize and sell it privately for more than the offered cash.

How does Expected Value (EV) work?

EV helps you work out the long-term value of your entries. For example, if a comp has a 1-in-100 chance of winning a £1,000 prize and costs you £1 to enter, the EV is £10 per £1 spent. This means for every £1 spent entering these comps you’d expect to make £10 going forward (a huge return on your investment!).

Is this gambling?

Yes – and it can be addictive. Please gamble responsibly.

Will competition providers accept my free postal entries?

Most will — but not all. Some competition companies are great at handling free postal entries, while others can be a bit more relaxed. It’s always worth checking before the draw takes place to make sure your entry has been received.


If a provider claims they “don’t receive” postal entries, it’s usually best to avoid them in future or reach out publicly on platforms they can’t easily ignore (like live streams, social media comments, or reviews).


That said, it’s not worth being aggressive — without these companies running draws, there’d be nothing to enter. A polite nudge usually goes a lot further.

Should I share competitions I’m entering with others?

Absolutely! Sharing is one of the best parts of comping. It helps others discover new sites (just like you did when you first started), and it builds a stronger, more informed community. The more people involved, the more accountability these companies have — and the more tips, tricks, and wins you’ll all learn from. Comping is always better when done together — the community is the best way to learn and grow.
