LOOKING to triple your betting balance this week? You can grab a massive 300% bonus with the latest bet365 bonus code.
Whether you are backing a team in the bumper midweek Premier League schedule or eyeing up a winner for the Tingle Creek at Sandown, here is how to unlock up to £30 in free bets today.
What is the bet365 bonus code?
The bet365 bonus code for December 2025 is SUN365.
New customers can copy this code and paste it into the ‘Bonus Code’ box when signing up and get 300% matched bonus in free bets.
Why use it? Because you don’t have to be a big spender to get involved. Unlike many bookies that demand a £10 minimum, bet365 allows you to start smaller.
If you deposit and bet just £5, you will still qualify for the 300% bonus, giving you £15 in free bets.
How to claim the bet365 sign up offer
It takes less than three minutes to get set up. Follow these steps to ensure you qualify:
- Click here to register a new account at bet365.
- Fill in your details and paste the code SUN365 into the ‘Bonus Code’ box on the final screen.
- Crucial Step: Make a deposit of between £5 and £10.
- Tip: We strongly recommend using a Debit Card for your first deposit. As per the T&Cs, Apple Pay, Google Pay, and PayPal are excluded from this offer unless you complete a lengthy postal verification process.
- Place a qualifying bet on any sport (football, racing, tennis) at odds of 1/5 (1.20) or greater.
- Once that bet settles, your Free Bets (3x your deposit) will be added to your account balance.
How does the offer work?
This is a straightforward “Matched Deposit” offer, but paid out in free bets (Bet Credits).
The standout feature of this offer is the Zero Wagering Requirements on your free bet winnings. If you use your £30 free bet to back a winner, the profit is yours to keep in cash (minus the free bet stake).

Why join bet365?
There is a reason bet365 is often picked as the #1 among the best online bookmakers. While other sites fight for attention with flashy gimmicks, bet365 wins on the fundamentals that serious punters care about.
Here are three reasons why they are the market leader:
1. The highest payout limits
If you land a massive accumulator, you want to know you will get paid. While many smaller bookmakers cap daily winnings at £100,000 or £250,000, bet365 has the highest ceilings in the industry.
For top-tier football (like the Premier League and Champions League), they pay out up to £2,000,000. It gives you peace of mind that your life-changing win won’t be capped by the small print.
2. The best app in the business
Speed matters, especially when betting in-play. The bet365 app is widely regarded as the fastest and most stable on the market. Whether you are cashing out in the 90th minute or building a Bet Builder seconds before kick-off, the sports betting app handles it without lag or glitches.
3. Live Streaming
bet365 broadcasts thousands of live events every year directly to your phone or tablet. From European football leagues (like La Liga and Serie A) to Tennis Grand Slams and daily Horse Racing, you can watch the action unfold live as long as you have a funded account or have placed a bet in the last 24 hours.
4. Official Champions League Partner (Free Tickets)
bet365 is now the first official betting partner of the UEFA Champions League. This isn’t just a badge on the website—it means real value for you.
As an account holder, you can enter the Big Ticket Giveaway. This is a free-to-enter ballot that gives away thousands of tickets to the biggest matches in Europe every single matchweek. You don’t even need to place a bet to enter; you just need a verified account.
bet365 ongoing promotions for existing customers
The welcome bonus is just the start. bet365 is famous for having the “stickiest” offers in the business, which keep punters coming back week after week.
Here are the top offers you can use right now:
2 Goals Ahead Early Payout
This is widely considered the best football promotion in the UK. If you back a team to win in the Premier League, Champions League, or other top leagues, and they go 2-0 ahead at any stage of the match, bet365 settles your bet as a winner immediately.
It doesn’t matter if the opposition fights back to draw 2-2 or win 3-2. You have already been paid.
100% Acca Boost
Love a weekend accumulator? bet365 has recently upgraded their accumulator bonus. You can now earn up to a 100% cash bonus on winning accas across more than 80 leagues and competitions.
The boost starts from 2.5% for a double and increases with every selection you add, peaking at a massive 100% for 20-fold accumulators.
Sub On, Play On
There is nothing worse than betting on a player to score or be carded, only for them to limp off injured in the 10th minute.
With Sub On, Play On, if your selected player is substituted before half-time, your stake is automatically transferred to the player who replaced them. Your bet stays alive for the full 90 minutes.
Tennis Retirement Guarantee
If you place a pre-match bet on a player to win a singles match from any ATP, WTA or Grand Slam event, you are covered against injuries.
If the opposing player retires hurt during the match, bet365 will pay out your bet as a winner, regardless of the score at the time.
Best Odds Guaranteed
For horse racing fans, best odds guaranteed are essential. If you take a price on a horse (e.g. 3/1) and the Starting Price (SP) ends up being bigger (e.g. 5/1), bet365 will pay you out at the bigger odds.
Position Payout
This is a game-changer for horse racing punters who find “Each Way” betting confusing. Instead of a standard place payout, Position Payout rewards you based on exactly where your horse finishes.
- Higher Finish = Bigger Win: You get a different price for finishing 2nd, 3rd, or 4th. The closer to 1st you get, the more cash you win.
- Fixed Odds: Unlike Each Way bets where the place part is a fraction (e.g. 1/5) of the win odds, Position Payout gives you a fixed price for every position before the race starts. You know exactly what you stand to win.
Racing Value (Double Result & No Rule 4)
bet365 offers a suite of “Racing Value” perks that save you money on frustrations common with other bookies:
- Double Result: If your horse crosses the line first but is later disqualified (e.g. for a steward’s enquiry), bet365 pays out on both the disqualified horse and the official winner.
- No 5p Rule 4: If a horse is withdrawn at odds between 10/1 and 14/1, most bookies deduct 5p from every £1 of your winnings. bet365 has abolished this deduction.
- Non-Runner No Bet: On selected Ante-Post races, if your selection doesn’t run, you get your money back in cash—no questions asked.
Extra Time Extra Chance (Rugby)
There is nothing worse than your rugby bet losing because the game ended in a draw after 80 minutes.
With this offer, if your Rugby League or Rugby Union match goes to extra time, your pre-match bet stays active.
- If you backed a team to win in the “Match Result” or “Second Half” market, your bet continues into extra time.
- If they win in extra time, your bet is settled as a winner.

Frequently asked questions about bet365 bonus code, free bets, and offers
1. What is the best bet365 bonus code for December 2025?
To claim your 300% bonus, use code SUN365. Enter this in the ‘Bonus Code’ box when creating your account to unlock the Bet £10 & Get £30 offer immediately.
2. Can I claim the offer with a £5 deposit?
Yes. While many bookmakers require a minimum £10 deposit, bet365 is one of our picks for low deposit betting sites, and allows you to start with just £5. If you deposit and bet £5, you will receive £15 in free bets (300% match). To get the maximum £30 bonus, you need to deposit and bet £10.
3. Why can’t I use Apple Pay or PayPal for my first deposit?
For your first deposit only, bet365 advises using a Debit Card. Due to banking regulations, e-wallets like PayPal and Apple Pay often require additional identity verification (Postal Verification Code) before they are eligible for welcome bonuses. Using a Debit Card ensures you qualify for the offer immediately without delays.
4. Do I get my free bet stake back if I win?
No, this is industry standard. When you place a bet using your Free Bets (Bet Credits), the returns will include your winnings only, not the stake.
- Example: A £10 cash bet at 2/1 pays £30 (returns + stake).
- Example: A £10 free bet at 2/1 pays £20 (winnings only).
5. How long do bet365 withdrawals take?
bet365 is one of the fastest paying bookmakers in the UK. If you use a Visa Debit card enabled with Visa Direct, your winnings will often hit your bank account in under 2 hours (sometimes instantly). Other methods, like PayPal, are also processed, usually within 24 hours.
6. Is there a wagering requirement on the Casino Free Spins?
No. This is a rare and valuable feature. If you claim the “New Player” Casino offer (up to 100 Free Spins), any winnings you generate from those spins are paid as cash. There is no requirement to re-bet your winnings before withdrawing.
7. When do my free bets expire?
Your Bet Credits will expire 7 days after they are added to your account if you do not use them. Be sure to use them on the midweek Champions League or weekend Premier League fixtures so you don’t lose them.
8. What happens if the match I bet on is postponed?
If your selection is void (e.g. a postponed match or a push), your stake is returned to your account. If you used Bet Credits for that bet, the credits are returned to your balance so you can use them again.
