About this video: Exchange Commission Explained
Exchange Commission Explained shows how a betting exchange makes its money. Instead of building a margin into the odds, it takes a percentage of your net profit in each market. So if you lose overall in a market, you pay nothing.
First, the video compares rates. One major exchange charges up to 5% as standard in the UK, while several others advertise 2%. Next, it works through a back bet of £20 at 3.0. The £40 profit loses £2 at 5%, so you keep £38.
Then it explains effective odds. For example, 3.0 at 5% commission pays the same as 2.90 at a bookmaker, and the gap grows with the odds. It also covers a lay bet, where a £20 win at 5% becomes £19.
Finally, it shows a trade. You back £20 at 3.0 and lay £24 at 2.5, which locks in £4. Because both bets sit in one market, you pay 5% once, so you keep £3.80. As a result, always record profit after commission.
However, rules and offers change. For that reason, we check every video against the Gambling Commission and other official sources. In fact, we last checked this one on 13 October 2026.

Exchange commission is the fee a betting exchange charges on your winnings. Here’s how it’s worked out on a back bet, a lay bet and a trade, and how to compare rates.
Instead of building a margin into the odds, an exchange takes a percentage of your net profit in each market. It doesn’t charge on your stake, and if you lose overall in a market, you pay nothing.
One major exchange charges up to 5% as standard in the UK, and several others advertise 2%. Rates change, so read your exchange’s current terms.
For example, you back a team for £20 at 3.0, and it wins. That’s £40 profit. 5% commission takes £2, so you keep £38.
So 3.0 at 5% pays the same as 2.90 at a bookmaker. At 2%, it’s worth 2.96. The gap grows with the odds, so commission matters more on longer prices.
When you lay, you’re the bookmaker. Lay a £20 stake at 3.0, and your liability is £40. If the team loses, you win £20, minus 5%, so £19.
Then on a trade, back £20 at 3.0, and lay £24 at 2.5. That locks in £4 either way. You pay 5% just once, 20p, and keep £3.80.
That looks small, but scalpers make hundreds of trades, so commission adds up. Always record your profit after commission, because a method that wins before it can lose after it.
