Arsenal v Chelsea Offer – William Hill

It’s Arsenal v Chelsea in the Premier League on Sunday and William Hill are getting in on the action! Place a £1.00+ Build #YourOdds bet on Arsenal v Chelsea and William Hill will match our stake as a free bet up to £5.00. Translated into matched betting terms, this gives us a guaranteed profit of £3.24 and here’s how…

Key terms

  • Applies to bets placed between 15:00 on Friday 20th August 2021 and 16:30 (kick-off) on Sunday 22nd August 2021.
  • We must click ‘Claim here’ on the promotion page to be eligible.
  • Applies to Build #YourOdds bets placed on Arsenal v Chelsea.
  • Minimum stake of £1.00.
  • Minimum odds of 1.20 (1/5).
  • Matched free bet up to £5.00.

Qualifying bet

It’s entirely up to you how you play this offer.

We could take a speculative approach and not lay our Build #YourOdds bet. If our bet loses, we know that by using straightforward matched betting, we should be able to convert our £5.00 free bet into 80% cash, so £4.00. That means the most we can lose on this offer is £1.00 and we could make a nice profit.

If we lay our qualifying bet though, we can lock in a guaranteed profit.

So, looking at the selections available, we could place our qualifying bet on Result – Chelsea / Both Teams to Score – No at back odds of 2.80 (9/5). The lay odds are currently 3.25.
