Grosvenor Sign Up Offer – £30 in Free Bets

The Grosvenor sign up offer is one that’s not to be missed. Simply sign up, bet £10 and Grosvenor will give you £30 in free bets. Translated into matched betting terms, this gives you a guaranteed profit of £23+. Let’s work through it one step at a time.

Key terms

  • Available to customers who sign up through the promotional page.
  • Minimum stake of £10.
  • Minimum odds of 1.50 (1/2).
  • 3 x £10 free bets credited upon settlement of qualifying bet.

The strategy

This is a straightforward ‘Bet X, Get X‘ offer.

To claim the £30 in free bets, you’ll need to bet £10 on football at odds of 1.50 (1/2) or greater. You can then use straightforward matched betting to convert your free bets into cash.

Qualifying bet

It’s entirely up to you what football market you place your qualifying bet on, but you’ll need to find a selection with close back and lay odds. The big televised matches are the best place to start looking or any other popular matches where plenty of bets will be placed.

If you’d like more information about qualifying bets and how they work, please see my qualifying bets guide.

I’ll use some example odds to illustrate how this offer should be done. Let’s say Chelsea are back odds of 1.50 and lay odds of 1.54 to win a football match.

Place £10.00 on Chelsea @ 1.50 = Potential profit of £5.00

Betfair logo

Lay £10.07 on Chelsea @ 1.54 = Potential liability of £5.43

Let’s have a look at your potential profit/loss for each outcome…

Chelsea win+ £5.00– £5.43£0.43 loss
Chelsea lose or draw– £10.00+ £9.56£0.44 loss

So, regardless of whether Chelsea win, lose or draw, you’ll incur a small loss of no more than £0.44. It’s worth it though, as you’ve just qualified for £30 in free bets!

Free bets

Your 3 x £10 free bets will be applied to your account upon settlement of your qualifying bet. The free bets will be valid for 7 days and free bet stakes will not be returned with any winnings.

Repeat the matched betting process for each of your free bets, but this time select the ‘Free Bet‘ option on the calculator. If you’re still a bit unsure of the process and would like to walk through using your free bets step by step, see my free bets guide.

You should be able to get £24 cash (80%) from your £30 in free bets. If you take into account your maximum qualifying loss of £0.44, this gives you a guaranteed profit of £23.56 on the Grosvenor sign up offer!
