How to Claim a Betting Offer as a New Customer
Every bookmaker has its own process, but most welcome offers follow a similar pattern. To make sure you don’t miss out, here’s a step-by-step guide to claiming your free bet:
- Click the ‘Register’ or ‘Open Account’ button at your chosen bookmaker.
- Fill in your personal details (name, date of birth, email, mobile number, address) and create a username and password.
- Enter a bonus code if one is required — most offers activate automatically, but always check the terms.
- Make your first deposit, ensuring you use an eligible payment method. Note that some offers exclude e-wallets like Skrill or Neteller.
- Place the qualifying bet, paying attention to the minimum stake, minimum odds, and eligible sports or markets. Cash-out is usually not allowed on qualifying bets.
- Once settled, your free bets will be credited. Use them before the expiry date or they’ll be removed.
- Remember: free bet stakes are not returned with winnings — only the profit is paid out.
- Sports free bets usually carry no wagering requirements on winnings, but attached casino bonuses often do. Meet any requirements within the time limit if you want to withdraw those winnings.

Understanding the Terms & Conditions of Betting Sign-Up Offers
Welcome offers always come with terms attached, and it’s important to understand the basics before claiming. Here are the key points to check on every bookmaker’s promotion:
- Wagering Requirements: Most sports free bets have no wagering on winnings, but casino bonuses often do. Always check if play-through is required.
- Minimum Odds: Your qualifying bet usually needs to be placed at even money (2.0) or higher. Short-priced favourites rarely qualify.
- Expiry Dates: Free bets typically expire within 7 days of being credited. Use them quickly to avoid missing out.
- Eligible Payment Methods: Debit card and Apple Pay are usually valid, but Skrill and Neteller often do not count.
- Bet Type Restrictions: Some offers exclude certain markets (like virtual sports) or cashing out your qualifying bet. Always check the small print.
What Is the Difference Between Betting Offers and Free Bets?
The two terms are often used interchangeably, but they’re not the same thing:
- Free Bets: You stake with tokens credited by the bookmaker. Winnings are paid out, but the free bet stake itself is not returned.
- Betting Offers: A wider category that covers free bets plus other promos such as odds boosts, money-back specials, acca insurance and profit boosts.
Example: a “Bet £10, Get £30” deal is a free bet promotion, while an “odds boost” or “money back if your horse finishes second” is a betting offer.
Different Types of Bookmaker Offers Explained
Bookmakers use a range of promotions to attract and reward customers. Here are the most common betting offers you’ll come across in the UK:
- Matched Bet Offers: Your first deposit or bet is matched with free bet tokens. Popular with new customer sign-ups.
- Free Bets: Tokens credited by the bookmaker that let you place a bet without risking your own cash. Winnings are paid, but the stake isn’t returned.
- No Deposit Free Bets: Rare in the UK market, but occasionally offered abroad. No deposit needed to claim.
- Enhanced Odds Offers: Boosted odds on a player, team or horse. Usually limited to small stakes with winnings paid as free bets.
- Acca Insurance: Money back as a free bet if one leg of your accumulator lets you down.
- Money Back Specials: Refunds or free bets if a specific event happens, e.g. your horse finishes second.
- Best Odds Guaranteed (BOG): If the SP is bigger than the odds you took, you’re paid at the higher price on horse and greyhound racing.
- Early Payouts: Your bet is settled as a winner if a trigger condition is met (e.g. football team goes 2 goals ahead), regardless of the final result.
Accepted Payment Methods for Betting Offers
Not every deposit method qualifies for welcome offers. Debit cards are the most reliable option, while some e-wallets are excluded. Always check the terms before funding your account.
- Debit Cards: Safest choice — almost always valid for free bet offers.
- Apple Pay & Google Pay: Commonly accepted, though not universal.
- PayPal: Often valid, but excluded by some bookmakers.
- Skrill & Neteller: Frequently excluded — avoid if claiming sign-up bonuses.
- Other methods: Bank Transfer, Paysafecard, Trustly, ecoPayz, Revolut and Boku may qualify depending on the bookmaker.
