There are many attractions to opening a new betting account: excellent odds, access to free-to-play games, live streaming options... the list goes on. However, for many punters, the most appealing perk is the welcome offer.

In the world of welcome offers, aka sign-up deals or new player promotions, the Bet and Get deal is among the most widely available. A quick scan of the market reveals a host of Bet £10 Get £10 and Bet £10 Get £20 promotions. But why stop at £20?

There are sites that really push the boat out with a Bet £10 Get £40 in Free Bets welcome offer. Read on to discover how these deals work, how to claim them, key terms, and a selection of the best Bet £10 Get £40 offers currently available.

Bet £10 Get £40 offers deliver exactly what they promise. New customers who place a £10 qualifying bet receive £40 in Free Bets. Note that this is always Free Bets, not free cash. As nice as it would be to receive £40 in free cash, any betting site offering such a deal may soon find themselves out of business. The best betting sites can be generous, but not that generous.

The £10 qualifying bet is a standard £10 bet using your own money. This bet must meet the conditions listed in the offer terms – be sure to read the terms in advance. Qualifying bet conditions are most commonly odds-related, e.g., the qualifying bet must be placed at odds of even money (2.0) or higher.

Once your qualifying bet settles, any winnings will be added to your account as normal. Provided you have met the offer terms, your £40 in Free Bets will then be credited.

Depending on the offer, your Free Bets may arrive in a variety of forms. You may receive 4 x £10 Free Bets to use as you please. Alternatively, the Free Bets may be restricted to a particular bet type or market, e.g. 1 x £10 Free Bet Builder Bet, 1 x £10 Free Acca Bet, 1 x £10 Free Horse Racing Bet, and 1 x £10 Free Correct Score Bet. Free Bets usually have minimum odds rules, e.g. Free Bet must be placed at odds of 4/5 (1.80) or higher.

When you place a bet using a Free Bet, the Free Bet stake is not included in any returns. For example, a £10 winning bet at 3/1 would ordinarily return £40 (£30 in winnings + your £10 stake). If you placed this bet using a Free Bet, you would receive only the £30 in winnings.

Last but not least, check the expiry date. Most Free Bets must be used within a specified time frame, e.g. Free Bet is valid for 7 days from the date of issue.

When claiming a Bet £10 Get £40 offer, the exact process may vary slightly between bookmakers. Some welcome offers are automatically linked to the sign-up process, while others require you to opt in or enter a Promo Code.

1. Choose Your Bet £10 Get £40 Offer - Rather than diving into the first offer you see, scan a few deals and choose the most appealing option; e.g. if you only bet on horse racing, you may not get much value out of a promotion that offers £40 in free football bets. Our bookmakers table lists a selection of the latest Bet £10 Get £40 Welcome Offers.
2. Register for a New Account - Having chosen your offer, click one of our links to take you to the relevant sign-up page. Look for an option labelled “Register”, “Join”, or “Sign Up” – usually located towards the top right of the screen. Select this option and follow the site's sign-up process – it usually only takes a couple of minutes.
3. Complete the Verification Process - As part of the Know Your Customer (KYC) process, the betting site will need to verify your identity. This may be done electronically in the background, or you may be asked to provide photo ID and proof of address.
4. Deposit £10 or More - Deposit at least enough to cover the stake for your qualifying bet. Before you deposit, check whether any payment methods are excluded from the offer. Deposits made using a valid debit card are usually eligible, but some sites exclude deposits made via other methods such as e-wallets.
5. Place Your Qualifying Bet - First, check the offer terms – eligible markets, minimum odds, etc. Next, find a selection that ticks all the right boxes and place your £10 qualifying bet.
6. Enjoy Your Free Bets - Once the qualifying bet has settled, the free bets should be credited to your account.

At any one time, there are likely to be several Bet £10 Get £40 offers available to UK punters. The way in which the £40 reward is structured can vary considerably between bookmakers. In our opinion, the following four deals are among the best Bet £10 Get £40 offers available as of October 2026.

Bet £10 Get £40 offers always catch the eye and can be a great way to get started with a new betting site. Like all bookie promos, these deals come with attached terms and conditions.

While the exact welcome offer rules vary between bookmakers, the following are the most common terms and conditions you will encounter with Bet £10 Get £40 offers:

• Eligibility - Many offers are restricted to new UK customers and are usually limited to one offer per person, household, IP address, or payment method.
• Payment Methods - Depending on the bookmaker, deposits made via certain payment methods may not be eligible for the offer. E-wallets such as PayPal, Skrill, and Neteller are the most commonly excluded methods.
• Minimum Deposit - Most offers come with a minimum deposit stipulation. This will usually match the value of the qualifying bet.
• Qualifying Bet - As the “Bet £10 Get £40” name suggests, you will need to place a qualifying bet to earn your free bets. You must place this bet with real money, on eligible markets, and at the minimum odds stated in the offer. Before placing your first bet, be sure it meets the odds and market requirements.
• Free Bet Types - You will usually receive 4 x £10 Free Bets. Depending on the bookmaker, the Free Bets may be for specific sports, markets, bet types, etc., and will usually have a minimum odds requirement. If the markets/sports attached to the Free Bets don’t interest you, you may find a more suitable offer elsewhere.
• Stake Not Returned - Free bet stakes are not included in any returns, e.g. if you place a £10 Free Bet on a 5/1 winner, your total returns will be £50, rather than the £60 you would receive had you placed the bet with real money.
• Expiry Date - This is one of the most crucial terms to be aware of. Almost all Free Bets have an expiry date. Make sure you use your bets in time so they don’t go to waste.
