STEP 1: Finding your Qualifying Bet

i) Switch to Decimal Odds Format

  • On desktop look for ‘Odds Format’ on the second menu bar and switch to decimal
  • On mobile click the menu icon and go to ‘Odds Format’ and select decimal

ii) Choose a popular league or cup

Examples include the Premier League, La Liga, Champions League, Euro 2020 etc.

To make life simpler for you we often provide lists of good Qualifying Bets to do in our Potential Bet Selections blog

iii) Select teams which have odds above the minimum odds of 1.51

For this first qualifying bet, we recommend selecting a team to bet on at William Hill with odds between 1.51 and 2.80. This is to keep your liability (balance needed in Betfair) low.

For clarity, if you select a team with odds of 1.40 (which is below the minimum odds), and place this bet, William Hill will not then grant you your free bets.

iv) Check the Betfair Exchange lay odds and choose the team which have the closest lay odds to the odds at William Hill

(If you don’t have Betfair Exchange yet you can sign up here to get a £20 risk-free bet)

Ideally you need a maximum 10% (or around 0.2) increment between the back odds at William Hill and the lay odds at Betfair.

For example, if the team you select at William Hill have odds of 2.3, your Betfair lay odds should not be higher than 2.5. This is  to minimise your qualifying loss.

STEP 2: Calculate the Lay Bet Amount

Using the Qualifying Bet Calculator

You will now need to enter:

  1. Your stake amount at the bookmaker (minimum is £10 but we recommend do a £20 bet or more if you can to appear as a good customer from the start)
  2. Your back odds at the bookmaker (must be minimum of 1.51)
  3. The pink box lay odds from Betfair

The calculator then works out your lay stake amount.

This is the amount you will use at Betfair for your against bet.


> At this point you must always check the liability amount on your calculator. In our example here it is £27.40. Your balance in Betfair must be the same or larger than the liability amount. If your Betfair balance is less than the liability, you can not do your Qualifying bet until you top up your Betfair balance first.

> It’s also a good idea to check the liquidity available in Betfair is greater than your lay stake amount (the liquidity is the number in £ that is under your lay odds in the pink box) . Ideally your liquidity should be at least double your lay stake amount.

STEP 3: Placing your bets

IMPORTANT: Remember to not use any odds boosts offered in your betslip by William Hill for this first bet. They may not give you the free bets if you do use it. 

The matched betting rule is to always put your bookmaker bet through first. So place your bet at William Hill.

As soon as your bet at William Hill has been placed and confirmed, you must now use your lay stake (as shown in your calculator) to place your against bet at Betfair.

At Betfair, just click on your lay odds in the pink box, write the lay stake amount in on your betslip, then click Place Bet and Confirm Bet.

STEP 4: Profiting from your Free Bets

Your 2 x £15 free bets are normally credited as soon as you’ve placed your Qualifying Bet. They will appear in your betslip. They are valid for 30 days.

We now have to repeat the same process to do our Profit (Free) Bets that we used to do our Qualifying Bet – but with a few small changes…

i) Choose a team with higher odds to make a larger profit

We recommend doing each of the two £15 free bets separately on two different teams (from different games) if you can.

We need to find bets with higher odds in order to extract a larger profit from each of the free bets.

We have created a table for you below to see what amount of liability you will need in Betfair to obtain a certain profit from each of the £15 free bets.

(Balance needed in Betfair)

To help you out, we also talk about the best matches to place your free bets on in our weekly Potential Bet Selections Blog.

ii) Open the Profit Bet Calculator

Enter your free bet stake, with your back odds from William Hill and lay odds from Betfair.

The calculator will work out the lay stake amount you need to use at Betfair to make your profit. Here’s an example of what your calculator will look like:



Before placing your free bet, remember to do your two important checks: 

Betfair balance is greater than the liability in the calculator

Liquidity at Betfair (numbers in £ under odds in pink box) is greater than your stake amount

iii) Select to use your free bets in the bet slip

As you know, you will make your profit using the free bets provided by William Hill, so don’t forget to select to use the Free Bet in your bet slip before placing your bet at William Hill.


HOT TIP: It’s good practice to double check everything before in your betslips before placing your bets. 

Once the free bet is confirmed at William Hill, then you can lay the bet off at Betfair using the lay stake worked out by your Profit Bet Calculator.

Now all you have to do is repeat the process with your remaining £15 free bet.


That’s another bookmaker down, and you should have made £15+ profit from these William Hill free bets – and you’re still just getting started!

#WDPHotTip – Fake Mug Bets & Checking your Email!

If any of your bets win at William Hill, consider making a few fake mug bets before withdrawing your cash. For these fake mug bets you can use any odds boosts offered by Hills. Each fake mug bet  will “cost” you around 40-80p, but they are a really great way to increase your chances of receiving private email promotions from them to make even more profit going forward…
