Matched Betting Explained: A Simple Beginner’s Guide

If you’ve heard about matched betting but don’t know where to start, this guide is for you. No hype, no jargon, and no assumption that you already understand betting.

I’ve been matched betting for over 15 years. I don’t treat it like gambling; I treat it like a process. Once you understand the steps, it becomes repeatable, predictable, and surprisingly dull. That’s a good thing.

If you’re still deciding whether matched betting is actually worth doing, read Is matched betting worth it in 2026? first.
This page shows you how it works.

What is matched betting? (simple explanation)

Matched betting is a way of using bookmaker free bet offers to make money by covering all possible outcomes of an event.

In plain English:
• You place a normal bet with a bookmaker
• You place an opposite bet elsewhere
• One bet wins, one loses
• The free bet you unlock creates the profit

You are not trying to predict results. You are removing uncertainty.

What you need before you start

You don’t need gambling experience or sports knowledge. You do need a few basics.

1. A separate bank account (recommended)

This isn’t essential, but it helps.

• Keeps betting transactions away from daily spending
• Avoids awkward questions if you apply for a mortgage later

Lenders don’t like seeing lots of bookmaker transactions, even when it’s not gambling.

2. A betting exchange account (essential)

A betting exchange is where you place lay bets (bets that something will not happen).

The most popular exchange is Betfair because it has the most users and liquidity. Liquidity just means there’s enough money available to match your bets quickly.

3. At least one bookmaker account

Start with a bookmaker offering a small welcome bonus (£10–£20). Smaller bets mean less pressure while you’re learning.

Large bonuses can wait.

4. Understand decimals

Even if you’ve never gambled before, I’m sure you’ve heard odds mentioned before, such as evens or 100/1. But the trick to matched betting is using decimal odds instead, as it is far easier to make comparisons and means you can make more money.

I have made this handy table for a quick reference. And because I had nothing better to do.

Fractions, decimals and probability

It may seem a little confusing, but you will soon get to grips with it.

5. Understand the exchange

Exchanges are initially very confusing and can take a while to get your head around. Simply put, they are a place where you can bet against other punters. That means you can set your own odds and act as a bookie. It’s up to other customers if they want to accept your odds or not. Equally, you can accept other users’ odds.

A typical Betfair exchange market will look like this.

Blue relates to the back market. That means you think something will happen. So, in the case above, Preston to win is 4.2, the draw 3.3 and Watford to win 2.14.

Pink relates to the lay market. To lay something means that you think it won’t happen. Above, you will get 4.3 for Preston not to win, 3.35 for the game not to end in a draw and 2.16 for Watford not to win.

The cash numbers below the larger figures refer to the amount of money available on the market. So, you could bet a maximum of £367 on Preston to win. After that, the odds would drop to 4.1.

When it comes to matched betting, we usually don’t have to worry about the blue part of Betfair. We place our bet for something to happen at the bookie and place our lay bet (for it not to happen) at the pink option at Betfair.

It’s important to note that any money you win at an exchange will be charged a commission. In the case of Betfair, this is usually 5%.

Step-by-step: how matched betting works

Now you’re ready to make your first matched bet.

Step 1: Find a qualifying offer

Most bookmakers offer something like:

Bet £10 → Get a £10 free bet

Your goal is to unlock the free bet while losing as little as possible on the first bet.

Step 2: Choose a suitable event

You’re looking for:
• A popular sport (usually football)
• A liquid market
• Similar odds at the bookmaker and exchange

Football is safest. I avoid tennis because settlement rules vary too much.

Step 3: Place the back bet with the bookmaker

This is the normal bet.

Example:
• £10 on a draw at odds of 3.6

If it wins, you make money at the bookmaker.
If it loses, you move on to the next step.

As we aim to minimise our losses, we need to find odds that match closely between the bookmaker and the exchange. Fortunately, there are sites like oddschecker, which will give you a nice clear table of the odds on offer at exchanges and bookies. Bear in mind that some free bets require you to bet on a certain event, so you won’t get a choice.

Let’s say we can win a £10 free bet from Bet365 if we place a bet on RB Leipzig vs Liverpool.

Looking at the game on oddschecker brings up the below. These figures are for the win and the draw.

As you can see, the odds for Liverpool to win are 2.3 at Bet365 and 2.29 at Betfair. For RB Leipzig 3 at Bet365 and 3.09 at Betfair. And the draw, 3.6 at Bet365 and 3.52 at Betfair.

It’s important to note that the Betfair odds listed on oddschecker are to back (blue), not to lay (pink). As this is the case, you need to remember that they will be slightly higher, known as one tick.

Remember, we want odds on Betfair that are a close match to the bookie or even lower. The best option above is the draw. We get 3.6 at Bet365, and to lay the bet it will be 3.54 at Betfair. As I said above, the price to back the draw was 3.52, which means the lay price is one tick higher at 3.54.

Now we know the event we need to place our bet on, it’s off to Bet365 to put £10 on the draw.

Step 4: Place the lay bet at the exchange

So, what do we know? If the game ends in a draw, we’ll win £26 from Bet365. If it loses, then we’re £10 down. The trick we will do now is to try and ensure that we will win £10 at the exchange if the game does not end in a draw and lose £26 if it does. As you can see, the bets will cancel each other out.

This involves a clever bit of maths, but fortunately, there are calculators available or services like Outplayed.com will walk you through each bet so you don’t mess it up.

The fields you need to fill in are quite simple, and we’ve discussed them above.

The results underneath are the most important. It tells us that we need to lay £10.37 on the draw at the exchange. That means if the game does end in a draw, we will need to pay out £26.13 (our liability).

The results also explain to us that if our Bet365 bet wins, we will be £0.13 down and if our exchange lay wins, we lose £0.15. Either way, we qualify for a free £10 bet for a minimal loss.

Step 5: Use the free bet to make profit

Now, it’s time to use our free bet. When we receive the bonus depends on the bookie. Some issue it straight away, others when your first bet is settled, and some within a certain time.

But using the free bet works in almost exactly the same way as the bet above, except for one major difference. Your free bet is almost always SNR (stake not returned). If your £10 bet is successful, you only receive the winnings back, not the £10.

Usually, you can place your bet on any market you like. So you will need to return to oddschecker to find a good match.

So, the best match for us is on the draw. Bet365 will pay 3.2 whilst we can lay the draw at Betfair for 3.16 (remember, the figures at oddschecker show the back odds at Betfair).

We now move back to our handy matched betting calculator to see how much we need to bet.

We enter the figures as we did before. Except for this time, we change the bet type from normal to free bet (SNR).

The results at the bottom tell us that we need to set our lay stake at £7.07. And whatever the result of the match, we win £6.72 or £6.73. Taking away the loss from our first bet still gives us a profit of over £6.50.
