Best UK Prize Competition Sites: How to Choose
With so many UK prize competition sites to pick from, how do you know which ones are genuine, transparent and worth entering? This guide walks through what to look for — and shows where Nitrous stands on each point. No hype, just the checks that matter.
What to look for in a competition site
Use this checklist to compare any UK prize competition site. The more of these a site does, the more confidence you can have in it.
A genuine free postal entry route
A trustworthy skill-based competition always offers a no-purchase (free postal) entry route with the same chance of selection. At Nitrous, every single competition has one.
Published, verifiable entry lists
Look for sites that publish the full entry list for each draw so you can check the result yourself. Nitrous publishes every entry list — transparency is the whole point.
Skill-based entry
Entry should require correctly answering a skill-based question, not pure chance. Every Nitrous competition is skill-based.
A clear cash alternative
Good sites let winners take a cash alternative where one is offered, shown up front on the competition page. Nitrous shows the cash alternative where available.
Low, transparent ticket prices and odds
The best sites show the price per entry and the total number of tickets (your odds) clearly. Nitrous entries start from just a few pence with the odds shown on every competition.
Clear draw dates and published results
You should always be able to see when a competition draws and see past winners. Nitrous publishes draw dates and a full results and winners archive.
Independent reviews
Check independent reviews before you enter. You can read verified entrant reviews of Nitrous on Trustpilot.
