Which promo code offers the highest-value bonus?

The table below shows the best value bonus code.

    Seven Days of Racing Action

    Coming off the back of Cheltenham, expectations naturally adjust - four days at the Festival takes some following. The week ahead is a quieter affair, but there is still worthwhile racing on offer across Britain and Ireland.

    Friday (20th March)

    Newbury offers some Class 3 handicap action that stands up to scrutiny, and the track's novice hurdles have earned a reputation for unearthing useful horses. Musselburgh stages three £40,000 series finals that are among the better reasons to tune in on Friday. Lingfield handles the afternoon all-weather, with Dundalk and Wolverhampton taking over in the evening.

    Saturday (21st March)

    Bangor-on-Dee's Class 2 Virgin Bet Supports Safe Gambling Handicap Hurdle carries a prize worth chasing and deserves attention. Kelso has its own strong material, a Listed mares novice hurdle among the attractions, but Newbury is where the biggest prizes are - a mares' novices' hurdle final and a £100,000 bumper headline their card. Southwell and Newcastle cover the all-weather beats, Newcastle running through the evening. Ireland has no fixtures on Saturday.

    Sunday (22nd March)

    The return of Flat racing to the Curragh earlier this week carries into Sunday with a card at Naas, where the Listed Devoy Stakes and the Madrid Handicap are the races of most interest. Limerick hosts a Listed bumper and a graded novice chase, while Britain's Sunday contribution comes from lower-grade National Hunt meetings at Carlisle and Exeter.

Promo codes terms and conditions

There are always restrictions around bookmaker offers so ensure you read the terms and conditions before committing to using your betting promo code. Use the regulated bookmakers we have suggested to find your promo code and carefully check for the below restrictions.

  • Sign-up restrictions - in some cases, you are permitted only one betting account per household. If one or more of you already has an account with a bookmaker, you may be restricted. You may also need to use a debit card to make your first deposit rather than Apple Pay or Skrill.
  • Eligible markets - offers are often restricted to different types of bets and markets. For example a bonus code bet offer may only be available if you place it on a specific market.
  • Minimum stake - the stake you place will often be set at a minimum amount. Usually around £5, £10 or £20. If you place lower than those amounts, your bet will not be valid.
  • Minimum odds - if a horse is a short-priced favourite, you may be restricted to betting on that horse. Minimum odds are usually around 1-2 or 6-4.
  • Expiry after a specific number of days - make sure you use your bonus within the time period stated. For example, you often have seven days to claim a free bet.
  • Maximum winnings - to avoid huge payouts, bookmakers may restrict the amount you can win so identify what your payout is likely to be and if it is worth your time.
  • Withdrawal times- bookmakers have different withdrawal processing times. Bank transfers are typically longer wait times than Paypal or e-wallets.

    1. Debit cards - Visa Debit, Mastercard and Maestro are popular methods of payment and most commonly used to claim promo codes.

    2. E-wallets - PayPal, Neteller and Skrill are among the most used e-wallets and provide a secure method of payment.

    3. Bank transfers - this is also an option for those who prefer to make direct bank transfers, the only drawback is that it can take longer to complete the transaction.

    4. Paysafecard - prepaid cards are also accepted by a number of punters and ensure more privacy.

    5. Wire tansfers - this method is sometimes used for high-value transactions although longer processing times and higher fees are common.

Withdrawing your bonus

You are not able to withdraw the betting promo code free bets as cash. Once you have claimed your UK betting promos, the bet credits will appear in your betting account but cannot be withdrawn as cash.

You must use the free bets credit to place a subsequent bet. If your qualifying bet is successful, you can withdraw your winnings as cash. The return does not include your initial stake.
