Reviews of the Top Betting Exchanges
Only one of the two sites in our table is a true exchange, so it pays to know which is which before you sign up. Matchbook pairs your bet with another customer who wants the opposite result. Spreadex is a bookmaker and spread betting firm that lets you sell a market as well as buy it, which is close to an exchange but not the same thing.
1. Matchbook – Best for Low Commission
Matchbook has been around since 2004 and holds a betting intermediary licence from the UK Gambling Commission, which is what lets an exchange match your bet against another customer’s. UK customers pay just 2% commission on net winnings per market. Betfair charges 5%, so on a £100 winning market you keep £98 here and £95 there.
Liquidity is best on horse racing win markets and American sports. On lower-league football, you’ll sometimes find less money waiting to be matched than on Betfair. The app works on iOS and Android, with in-play betting and racing streams available to players.
To get the welcome offer, sign up with code NEW30 and settle two £10 qualifying bets: an exchange bet at 2.0 or longer, plus a multiple or Bet Builder with three or more legs at 3.0 or longer. You’ll get three £10 free bets within 72 hours, split between exchange bets, multiples and Bet Builders. Just don’t make your first deposit with Skrill, Neteller or Paysafecard, as that rules you out. Our Matchbook bonus code guide has the full breakdown.
If you’re opening your first exchange account, this is the one we’d start with. The only reason to look elsewhere is if you mostly bet on football outside the top leagues, where Betfair usually has more money waiting.
2. Spreadex – Best for Spread Betting
Spreadex isn’t a betting exchange. We’ve listed it because it gives you a way to bet against an outcome without one. While Spreadex offers some similar mechanics, such as the ability to sell a market (which can feel somewhat like laying a bet on an exchange), you are trading directly with Spreadex rather than matching bets with another customer. There is no commission and no waiting for someone to take the other side, but Spreadex sets every price rather than other punters.
The firm dates back to 1999 and runs fixed-odds betting and sports spread betting from a single account and app, with in-play markets, cash out, a bet builder and live streaming. Spread betting works on a number, such as total goals in a match: you buy if you think the result will finish above Spreadex’s quote and sell if you think it will finish below, and you win or lose more the further it lands from that quote. Losses can exceed your deposit, so learn how a market settles before you trade it.
If all you want is to lay horses, Spreadex is the wrong tool and Matchbook is the better pick. If you like the idea of betting on a number rather than a result, nothing else in this list does it.
The welcome offer is for the fixed-odds side. Stake £10 on a fixed-odds single or each-way bet priced 1/2 or longer, and three £10 free fixed-odds bets come your way, along with a bundle of free spread bets that you can only use once your account is set up for spread betting. The free bets last 28 days, and PayPal deposits don’t qualify. The Spreadex sign-up offer page shows how the free bets arrive over three days.
Betting Exchange Sites Compared
This table sets our two picks against Betfair Exchange and Smarkets, the other names UK exchange punters use most. We don’t currently list welcome offers for Betfair or Smarkets, so check their sites for live deals. Commission is the standard UK rate taken from net winnings on a market, and liquidity is our own rating of how much money is usually available to match.
| Bookmaker | Commission | Liquidity | Welcome Offer | Best For | Betting App |

| Matchbook | 2% | Medium | Bet £20 Get £30 in Free Bets | Low commission & horse racing | Yes |
| Spreadex | None (not an exchange) | N/A: you bet against Spreadex | Bet £10 Get up to £60 in Free Bets | Spread betting | Yes |
| Betfair Exchange | 5% | Highest in the UK | Not listed | Liquidity & Betfair SP | Yes |
| Smarkets | 2% | Medium | Not listed | Football & political markets | Yes |
Exchanges vs Standard Bookmakers
Exchanges and traditional betting sites both let you bet on the same events. The difference is in who you are betting against and how the site makes its money.
- A bookmaker takes your bet itself. An exchange only introduces you to another customer who wants the opposite outcome.
- On an exchange you can back a selection to win or lay it to lose. Laying puts you in the bookmaker’s seat, accepting someone else’s stake.
- When you lay, you cover the backer’s potential winnings, worked out as stake × (odds − 1). Laying £20 at 4.0 means a £60 liability, which has to be in your account before the bet is matched.
- Bookmakers build a margin into every price. Exchanges set no prices at all and instead take a commission, usually between 2% and 5%, from your net winnings on each market.
- Because exchange odds come from customers rather than a trader, they are often bigger than a bookmaker’s, although commission trims the final return.
- An exchange bet only stands once someone accepts it, so in quiet markets part of your stake can sit there unmatched.
- You can back at one price and lay at another, locking in a profit or cutting a loss before the event ends. A bookmaker’s cash out does something similar, but on its own terms.
- Bookmakers run far more free bets and price boosts than exchanges do.
Pros and Cons of Using a Betting Exchange
Pros
- Prices are often bigger than at a bookmaker, particularly on busy horse racing and football markets
- Laying lets you bet against a selection, which no standard bookmaker allows
- You can trade a position in-play and take a profit before the final whistle or the winning post
- Commission is only charged on markets where you finish ahead, never on losing bets
- Low-commission exchanges such as Matchbook and Smarkets let you keep 98% of your net winnings
Cons
- A lay bet can cost far more than your stake, because your liability grows with the odds
- Smaller markets may not hold enough money to match a big bet at the price you want
- Commission comes off every winning market, so the true price is a little shorter than it looks
- There are fewer welcome offers and ongoing promotions than at mainstream bookmakers
- The price ladder and constant movement take time to get used to
Sports Betting with Exchanges
Exchanges list most sports, but horse racing and football account for most of the money traded. Their markets are deep enough to keep prices close to the real chance of each outcome, and there is racing or football to bet on almost every day of the year.
Football Betting
Match odds is usually the busiest football market, with correct score and the over/under goals lines behind it. Premier League and Champions League games draw the most money, and much of it is matched after kick-off, as prices react to every goal, red card and substitution. That in-play movement is what traders work with: back a team before the game, then lay it later at shorter odds to guarantee a return whatever the score. Betfair has the deepest football markets, while on Matchbook the top leagues match well but the lower divisions can be thin. For those smaller games, the best bookmakers for football betting usually give you a wider choice of markets than an exchange can.
Horse Racing
Horse racing has been at the centre of exchange betting from the start, and it still draws a big share of the money. You can back or lay horses in the win and place markets on the day, bet in-running while the race is on, or take an ante-post price weeks before a major festival. Laying is popular in racing because most runners in a big field lose, so opposing a short-priced favourite you don’t fancy is a natural use of an exchange. Betfair also runs its own starting price, Betfair SP, which no other exchange offers. Matchbook’s racing win markets are among its strongest, and its 2% commission is lower than Betfair’s standard rate. Horse racing betting with a bookmaker still has one perk an exchange can’t match: Best Odds Guaranteed, which pays you at the starting price if it beats the odds you took.
Responsible Gambling
Exchanges and spread betting carry risks an ordinary bet doesn’t. A lay bet can lose several times your stake, in-play trading moves fast enough to chase losses without noticing, and Spreadex spread bets can lose more than you deposited. Before you start, set deposit and loss limits in your account settings, and check the liability on every lay before you confirm it. Matchbook and Spreadex can also lock your account for a break or exclude you for longer periods. If betting is causing you problems, GamStop blocks you from every UKGC-licensed site in one step, and GamCare runs the free National Gambling Helpline on 0808 8020 133. You must be 18 or over to gamble in the UK.
