Free Postal Entry Competitions Explained (Step by Step)

Last updated 9 October 2026

In short: you can enter any Nitrous competition free by sending a postcard with your details, the competition, the question and your answer. Each correctly completed postcard is a free entry into the same draw, on equal terms with paid entries. It must arrive before the competition closes. Full instructions are in our terms.

Every UK prize competition worth entering offers a free way in. At Nitrous it’s by post, and it’s a genuine route: postal entries go into exactly the same draw as paid ones. Here’s precisely how to do it — and the small mistakes that cost people their entry.

Why the free route exists

It means nobody ever has to pay to take part. A free entry has the same chance as a paid one, which keeps competitions open to everyone and is part of running them fairly and lawfully.

How to enter by post: step by step

  1. Get a postcard. Entries must be on a postcard, sent with 1st or 2nd class postage.
  2. Write the competition name you’re entering.
  3. Write the question and your answer — the same skill question shown on the competition page.
  4. Add your details so we can match the entry to you and contact you if you win (the exact details required are listed in our terms).
  5. Post it to: Nitrous Competitions, 12 The Close, Barwell, LE9 8AS.
  6. Send it early. It needs to arrive before the competition closes.

Always check the terms before posting, as they’re the official and most up-to-date instructions.

The equal value guarantee

Where a competition’s paid ticket price is lower than the cost of your stamp, your postal entry is credited with the number of entries your postage would have bought at that price (rounded down, and never fewer than one). So a free entrant is never at a disadvantage — both routes go into the same draw on equal terms.
