Sister Sites Guide
Betfair did something in June 2000 that nobody had done before: it launched a betting exchange, a marketplace where punters bet against each other rather than against a bookmaker. The idea came from Andrew Black, a former professional gambler who understood that the biggest inefficiency in traditional betting was the bookmaker’s margin. Remove the bookmaker and let players set their own prices, and the value improves for everyone. That concept remains the foundation of everything Betfair is. Twenty-five years later, it still operates the world’s largest betting exchange, it’s now owned by Flutter Entertainment (the world’s largest online gambling company), and it shares a UKGC casino and bingo licence with one sister brand. Just one. That sister brand is Paddy Power, and the two of them make for one of the most distinctive pairings in UK-regulated gambling.
The Betfair sister sites in a nutshell
Betfair’s only formal sister site, on PPB Entertainment Limited’s UKGC licence 39426, is Paddy Power. That’s the complete licensed family on that account: two domains, two brands, both operated by the same Flutter Entertainment subsidiary. Sky Bet, Tombola and PokerStars are all Flutter-owned brands, but they sit on entirely separate UKGC licences and are not sister sites of Betfair in any regulatory sense. Below, I cover what that relationship with Paddy Power actually means, what makes Betfair genuinely different from every other bookmaker in the UK, and what players looking for something similar should know about the wider Flutter picture.

Betfair and Paddy Power: the sister site relationship
The UKGC domain list for PPB Entertainment Limited’s licence (39426) has just two entries: www.betfair.com and www.paddypower.com. That’s the complete, documented family on this licence. Before getting into the Paddy Power profile, it’s worth musing on what that pairing actually represents. These are the two brands that merged in 2016 to form Paddy Power Betfair, which later rebranded as Flutter Entertainment. They’re formally on the same licence, they share the same Malta-registered operator company, and they’re as different from each other in character and product identity as any two gambling brands in the UK market.
Paddy Power
My take: Paddy Power is the one genuine, UKGC-licensed sister site on the PPB Entertainment licence, and it’s a genuinely interesting contrast to Betfair. Both are major UK betting and gaming brands. Both are wholly owned by Flutter Entertainment, and they’re about as tonally different as two bookmakers in the same family can be. Betfair is analytical, data-forward, exchange-driven and primarily built for punters who understand what odds mean and want more control over how they bet. Paddy Power is irreverent, entertainment-first, promotions-heavy and built for an audience that wants to be entertained as much as to win. The Paddy Power retail presence (over 600 shops across the UK and Ireland) is one of the largest high-street betting operations in the country. The online product covers sportsbook, casino, bingo, poker and games. It carries one of the most famous betting shop identities in Irish and British culture.
Best for: Betfair players who want to explore the brand’s sister site and specifically want more traditional fixed-odds sportsbook access, in-shop betting through a large UK retail estate, or the kind of promotional-bonus-first approach that Betfair deliberately underplays in favour of competitive pricing.
What feels similar: Same PPB Entertainment UKGC licence (39426), same Flutter parent, same Malta-registered operator. The payment infrastructure and responsible gambling framework are shared at the Flutter level. A self-exclusion on either brand applies across both.
What feels different: Almost everything about the product experience. Paddy Power’s identity is built on personality and promotion; Betfair’s is built on the exchange and odds quality. Paddy Power has an extensive retail network that Betfair doesn’t. The casino and bingo lobbies at Paddy Power are promoted far more actively as primary products. The brand voices are completely different.
The angle: The one formal sister site on this licence, and one worth understanding clearly. Not a like-for-like alternative to Betfair’s exchange, but the most directly comparable product for a Betfair sportsbook or casino player who wants a more promotions-forward experience from the same regulatory family.
Sky Bet, Tombola, PokerStars: Flutter brands but not Betfair sister sites
Flutter Entertainment owns Sky Betting and Gaming, Tombola and PokerStars in the UK, and they’re all regulated by the UKGC. But they sit on entirely separate licence accounts and are not sister sites of Betfair in any regulatory or formal sense. Sky Betting and Gaming (Sky Bet, Sky Vegas, Sky Casino, Sky Bingo, Sky Poker) is licensed through Bonne Terre Limited. Tombola is licensed through Tombola International Plc. PokerStars operates through its own separate parent company, too. The UKGC’s position is clear: the company responsible for upholding regulatory requirements is whichever licence holder the consumer has conducted their gambling transaction with. Flutter itself holds no operating licence.
For a player trying to understand the sister site picture, this matters in practice. A self-exclusion at Betfair applies to Paddy Power on the same PPB Entertainment licence. It does not automatically apply to Sky Bet, Tombola or PokerStars on their separate accounts. Bonus eligibility restrictions apply within the PPB Entertainment account, between Betfair and Paddy Power, not across the entire Flutter family. Players who are doing their research carefully will want to understand this distinction rather than assuming that everything Flutter owns is a sister site of everything else Flutter owns.
Best picks by player type
If you want the one sister site on the same UK Gambling Commission licence
Paddy Power is it. Same PPB Entertainment licence, same Flutter parent, different character. Best for Betfair users who want a traditional fixed-odds sportsbook with a large retail network and a more promotion-led approach.
If you want a Flutter brand with bingo as a primary product
Tombola is the Flutter group’s specialist bingo brand, awarded EGR Bingo Operator of the Year in 2023. It operates under its own separate UKGC account (Tombola International Plc) and is not a sister site of Betfair, but it’s the Flutter answer for bingo-focused play.
If you want another Flutter sportsbook product
Sky Bet (Bonne Terre Limited, its own UKGC account) is the most full-featured Flutter sportsbook brand in the UK market outside of Betfair and Paddy Power. Again, not a Betfair sister site in the technical sense, but a Flutter-family product worth knowing about if the group’s brand quality rather than its specific licence structure is what you’re weighing.
How Betfair changed the UK betting market and why it still matters
Before June 2000, if you wanted to bet on sports in the UK, you placed your wager with a bookmaker. The bookmaker set the odds, took your money and kept an overround, the percentage by which the total probability implied by the book exceeds 100%. That overround, typically between 8% and 15% depending on the event and the market, was the bookmaker’s built-in edge. Every bet you placed was made at odds slightly less favourable than the true probability of the event.
Andrew Black, a former professional gambler and software developer, built Betfair around a different proposition. Instead of betting against a bookmaker, punters would bet against each other on a centralised exchange. The exchange would match orders, take a small commission (typically 5% of net winnings on a market) and facilitate the transaction. The result was that the overround disappeared, and the prices available on the exchange were, for most events, considerably closer to the true probability than anything a traditional bookmaker was offering.
The second innovation, one that traditional bookmakers still won’t offer, was the ability to lay a bet: to take the bookmaker’s position and offer odds to another punter. If you believed a horse wouldn’t win, you could lay it, setting the odds and taking the opposing punter’s stake if you were right. This transformed the product from a single-direction wager into a genuine two-sided market, and it created an entire category of specialist exchange bettor, the “layer,” who had previously had no way to express that kind of view efficiently.
Betfair merged with its rival betting exchange Flutter in December 2001. It listed on the London Stock Exchange in 2010. The Paddy Power merger came in 2016. The Stars Group acquisition (PokerStars, Sky Betting and Gaming) followed in 2020. Flutter Entertainment’s global revenue for 2025 was approximately £17 billion. None of that trajectory would have been possible without the exchange, and the exchange continues to generate a substantial proportion of Betfair’s UK revenue to this day. In 2023 and 2024, independent odds comparison studies consistently found that Betfair’s exchange offered the best match odds across major football leagues, pre-match and in-play, compared with any UK bookmaker.
The Cash Out feature, now offered by almost every UK bookmaker, was pioneered by Betfair. The 90 Minute Payout promotion, which pays out a winning 1×2 football bet at the 90-minute mark if a team is winning by two or more goals, was another Betfair first. The free daily Prize Pinball feature in the casino, a jackpot game that requires no additional stake, is the most recent example of the same philosophy: finding ways to give players something that competitors don’t.
The exchange and the sportsbook: two different products under one login
The Betfair Exchange and the Betfair Sportsbook are different products and operate under different UKGC licences, even though they’re accessed through the same account. The exchange is licensed through PPB Counterparty Services Limited (UKGC account 39439). The sportsbook and associated activities run through further Flutter subsidiaries. The casino and bingo products are licensed through PPB Entertainment Limited (account 39426), which is the account that lists both Betfair and Paddy Power.
For UK players, the practical implication is straightforward: you use one Betfair account for everything, but the underlying regulatory framework splits the exchange, sportsbook and casino across separate Flutter subsidiaries. That structure is more complex than most players need to think about during a normal session, but it becomes relevant when you’re trying to understand the full sister site picture, particularly the clarification that Paddy Power is the sister site of Betfair’s casino and bingo operation, not of the exchange specifically.
The welcome offer for the Sportsbook (Bet £10 Get £50 in Free Bet Builders and Accas) is for the fixed-odds sportsbook. Exchange bets are explicitly excluded from the qualifying wager and the free bets cannot be used on the exchange. If you came to Betfair primarily for the exchange, the standard sportsbook welcome offer is not the relevant starting point. The casino welcome offer (50 no-deposit free spins) is the one that falls under the PPB Entertainment Limited licence and connects most directly to the sister site picture on this page.
Ownership, licensing and a recent regulatory settlement
Betfair’s casino and bingo operations are licensed through PPB Entertainment Limited, registered at Spinola Terraces, Level 2, Mikiel Ang Borg Street, St. Julians, SPK 1000, Malta. UKGC account 39426 covers Remote Casino and Remote Bingo, both active from November 2014. PPB Entertainment Limited is a subsidiary of Flutter Entertainment plc, which is dual-listed on the New York Stock Exchange (FLUT) and London Stock Exchange (FLTR) and registered in Dublin, Ireland. Peter Jackson has served as Flutter’s Group CEO since 2018. The UK and Ireland division, which includes Betfair, Paddy Power, Sky Betting and Gaming and Tombola, is led by Ian Brown, who has held that role since September 2022.
The regulatory action on account 39426 is recent and significant. On 17 December 2025, the UKGC published a settlement involving four Flutter entities operating the Betfair and Paddy Power brands: PPB Entertainment Limited, PPB Counterparty Services Limited, Betfair Casino Limited and TSE Malta LP. The total settlement was £2,000,000. The action followed a compliance assessment of both brands’ remote operating licences in April and May 2024, which found failings in Social Responsibility controls. Specifically, all four licensees failed to comply with Social Responsibility Code Provision 3.4.3 on remote customer interaction, meaning the systems for identifying and responding to customers showing indicators of harm were not operating to the required standard. The settlement was accompanied by a public statement published on the UKGC’s register.
This is not the first time Flutter’s UK companies have faced regulatory action. PPB Entertainment received a £2.2 million fine in October 2018 for failing to protect customers showing signs of problem gambling and for inadequate AML checks. Bonne Terre Limited (Sky Betting and Gaming, a separate Flutter entity) received a £1 million penalty in 2018 and a further £1.17 million in 2022. Paddy Power received a £490,000 penalty in 2023 for sending promotional push notifications to self-excluded customers. The December 2025 settlement is the most recent in a pattern of enforcement across Flutter’s UK licences that has now totalled over £6.8 million across the group. Players deserve to know this context even where the products themselves are strong, and the regulated framework is clear.
The welcome offers: four distinct products, four separate deals
Betfair runs separate welcome offers for each of its product verticals, in line with the January 2026 UKGC rules on mixed-product promotions. Each is claimed independently, and only one can be active at registration.
Sports: Bet £10, Get £50 in Free Bet Builders, Accas and Multiples. Place a minimum £10 bet at odds of at least Evens (2.0) on any Sportsbook market within 30 days of registering. You’ll receive five £10 free bets, but with a specific restriction: they can only be used on Bet Builders, accumulators and multiples. Straight singles and exchange bets are excluded from both the qualifying wager and the free bet usage. Deposits must be made via Pay by Bank, debit card or Apple Pay. E-wallets do not qualify. Free bets expire after 30 days from being awarded, which is a generous window by UK market standards. The £50 return on a £10 outlay compares well with most UK sportsbooks on a pure ratio basis, though the accas-and-multiples restriction is the key term to understand before claiming.
Casino: 50 free spins without depositing, then 50 more. Register with promo code CASAFS and you receive 50 free spins on Jackpot King games (including Crabbin’ For Cash Extra Big Catch) at 10p per spin, with no deposit required. These spins expire after seven days. Once you’ve used the no-deposit spins, opt in for the second part: deposit and spend £10 on eligible Jackpot King or Daily Jackpot games and receive a further 50 free spins, also at 10p. All winnings from both batches are paid directly in cash with no wagering requirement. That no-deposit element on the casino welcome is genuinely rare in the UK market in 2026 and makes Betfair’s casino offer one of the most accessible in the market for trying the product before committing money.
Bingo: Play £10, Get £50. Deposit and play £10 on bingo tickets (code BINW50) and receive £50 in bingo bonus funds. Full terms available on the Betfair Bingo section of the site.
For existing customers across all products, the Prize Pinball daily jackpot is one of the more distinctive ongoing features: a free daily play in the casino that can win free spins, bonus funds or withdrawable cash without staking a penny. The existing Sportsbook promotion calendar focuses on odds quality, enhanced each-way terms on racing festivals, and selective accumulator insurance deals rather than the frequent offer flooding that some competitors use. That approach suits the exchange-and-odds-aware audience that Betfair has historically attracted.
Deposits, withdrawals and one genuinely unusual option
Betfair’s payment range is among the broadest in the UK market. Accepted deposit methods include Visa Debit, Mastercard Debit, Apple Pay, Google Pay, PayPal, Skrill, Neteller, MuchBetter, Paysafecard and Pay by Bank (instant bank transfer via open banking). Minimum deposits are £5 for debit cards and Apple Pay/Google Pay, and £10 for e-wallets and bank transfers. All deposits are instant, except bank transfers, which can take up to 2 working days. E-wallets and Paysafecard exclude you from the welcome offer, so if the bonus matters to you, use a debit card or Apple Pay for your first deposit.
The one payment option that genuinely distinguishes Betfair from other online bookmakers is the ability to deposit cash at any Paddy Power shop. Given that Paddy Power operates more than 600 UK and Irish betting shops, this is a meaningful practical option for players who prefer not to use online payment methods for their gambling account. The symmetry between the two sister brands runs right down to the cashier: Betfair’s online account and Paddy Power’s retail presence share enough infrastructure that cash deposits bridge the two.
Withdrawal timescales vary by method. PayPal, Skrill and Neteller typically clear within four to 24 hours. Visa Fast Funds can process near-instantly for eligible withdrawals up to £2,000, up to five times per day. Apple Pay and standard debit card withdrawals take two to five working days. Bank transfer runs to two to three working days for UK banks. An alternative withdrawal option, Prizeout, lets you convert winnings into gift cards from brands including Amazon and Uber Eats, sometimes with enhanced value. It’s a niche choice, but it exists. Betfair charges no withdrawal fees on any method.
Betfair operates the standard closed-loop withdrawal policy: you withdraw to the same method you deposited with, up to the value of your net deposit through that method. If you’ve used multiple deposit methods, you’ll need to close each loop separately before the remainder can go to your preferred withdrawal route. The closed-loop rules at Betfair are more frequently raised in player feedback than at most comparable operators, not because Betfair does anything unusual, but because the exchange nature of the platform means high-volume depositors encounter the mechanics more often.
Support and complaints
Live chat is the primary support channel and is available 24/7 via the betfair.com support page. Email support is also available for non-urgent queries. Phone support is referenced in the site’s help pages for certain account issues, though weirdly, the available hours vary by query type. The help centre at support.betfair.com is extensive and covers the exchange in particular detail, which reflects Betfair’s awareness that many customers are relatively new to exchange mechanics and need more explanation than a standard fixed-odds sportsbook requires.
One practical advantage is that as an exchange operator, Betfair produces considerably more market data transparency than traditional bookmakers. If you have a dispute about a bet or a market settlement, the exchange’s order book is auditable, and the terms around each market are set in advance and publicly visible. For exchange disputes in particular, this creates a more factual basis for resolution than the “bookmaker’s word” approach that governs fixed-odds settling at other operators.
For unresolved complaints, the UK regulatory framework applies fully. PPB Entertainment Limited (for casino and bingo disputes) is subject to UKGC account 39426’s compliance obligations. The December 2025 settlement covering social responsibility failings in customer interactions means the UKGC is actively monitoring how Betfair and Paddy Power identify and respond to customers who show indicators of harm. Players who feel their responsible gambling concerns aren’t being handled appropriately have a clear and meaningful escalation path through the UKGC’s complaint process, and the recent settlement means the regulator will be watching the operator’s response closely.
What I like, and what I don’t
What I like
- The exchange is still the best version of itself in the market. Nobody has built anything that meaningfully competes with Betfair’s exchange liquidity or market coverage in 25 years of trying.
- The no-deposit casino welcome spins are genuinely rare in 2026. Getting 50 free spins on Jackpot King games without having to deposit first puts the product in front of you before you’ve committed a penny.
- £50 in free bets from a £10 qualifying sports bet is one of the higher-ratio welcome offers in the UK sportsbook market. The 30-day expiry is more generous than most competitors’ seven-day windows.
- The breadth of the payment range, including PayPal, Skrill, Neteller, cash at Paddy Power shops and Prizeout gift cards, gives UK players more options than almost any other major operator.
- The Prize Pinball free daily jackpot is a small but meaningful commitment to giving existing players something for nothing every day.
- The exchange’s historical odds advantage over traditional bookmakers is documented and consistent across major football markets. That’s not a promotional claim; it’s what independent odds data shows.
What I don’t
- The December 2025 UKGC settlement is very recent and very relevant. £2 million across four companies for failing to identify customers showing harm indicators is a serious finding, particularly given it followed other recent fines and actions.
- The sportsbook free bets are restricted to Bet Builders, accas and multiples only. For a player who wants to use free bets on straight singles, Betfair’s offer is not the right structure.
- The exchange learning curve is steep. For players new to the concept, the Betfair interface can feel unfamiliar and the commission structure takes some understanding. The platform is powerful but not instantly intuitive.
- The closed-loop withdrawal policy generates more friction at Betfair than at comparable operators because high-volume exchange users deposit through multiple methods and encounter the rules more often.
My final verdict on the Betfair sister sites
Betfair’s sister site picture is simple, contained and well-documented: Paddy Power is the one other brand on PPB Entertainment Limited’s UKGC account (39426), and that’s it. Sky Bet, Tombola and PokerStars are Flutter-owned but sit on separate UKGC accounts and are not sister sites of Betfair in any regulatory sense. The distinction matters practically: self-exclusion, account linkage and bonus eligibility restrictions between Betfair and Paddy Power are governed by the PPB Entertainment licence, not by Flutter’s corporate structure.
The December 2025 UKGC settlement across four Flutter companies for social responsibility failings is the most important recent development for any player assessing this operator, and its recency makes it harder to dismiss than older resolved findings. The exchange remains genuinely unreplicated after 25 years. The no-deposit casino welcome is rare and honest. Paddy Power is the formal family; everything else with a Flutter logo is a different licence. For the player who understands all of that and comes to Betfair for what it actually does best, the exchange and the odds quality make a very strong case. For the player who came looking for a large, clearly structured sister site network, this is the wrong address.
FAQs about Betfair and its sister sites
What is the Betfair sister site?
The only formal sister site of Betfair on PPB Entertainment Limited’s UKGC licence (39426) is Paddy Power. Both brands appear as active domains on the same account. Sky Bet, Tombola and PokerStars are owned by Flutter Entertainment but sit on separate UKGC accounts and are not sister sites of Betfair in the regulatory sense.
Does the December 2025 UKGC settlement apply to Betfair?
Yes. On 17 December 2025, four Flutter companies, including PPB Entertainment Limited (which operates Betfair’s casino and bingo on account 39426), agreed a total settlement payment of £2,000,000 following a UKGC compliance assessment in April and May 2024. The assessment found that all four entities failed to comply with Social Responsibility Code Provision 3.4.3 on remote customer interaction, meaning the systems for identifying customers showing signs of harm were not working as required. The UKGC published a public statement on the findings.
Is Betfair’s exchange on the same UKGC licence as the casino?
No. The Betfair Exchange operates under a separate licence held by PPB Counterparty Services Limited (UKGC account 39439). The casino and bingo products are licensed through PPB Entertainment Limited (account 39426), which is the licence that also covers Paddy Power. The sportsbook runs through further Flutter entities. All are accessed through the same Betfair login, but they’re separately licensed.
Who owns Betfair?
Betfair is owned by Flutter Entertainment plc, the world’s largest online gambling company by revenue (approximately £17 billion in 2025). Flutter also owns Paddy Power, Sky Betting and Gaming, Tombola, PokerStars, FanDuel, Sportsbet and others. The UK casino and bingo operation is run through PPB Entertainment Limited, a Flutter subsidiary registered in Malta. Flutter itself is dual-listed on the New York Stock Exchange and London Stock Exchange and is registered in Dublin, Ireland.
What is Betfair’s current sports welcome offer?
New UK customers who place a minimum £10 bet on any Sportsbook market at odds of Evens (2.0) or greater within 30 days of registering receive £50 in Free Bet Builders, Accumulators and Multiples, split as five free bets of £10 each. Free bets expire after 30 days from being awarded. Exchange bets do not qualify for the offer. Deposits must be via Pay by Bank, debit card or Apple Pay. E-wallets do not qualify.
What is Betfair’s casino welcome offer?
New customers can register with promo code CASAFS to receive 50 free spins on Jackpot King games at 10p per spin, credited without requiring a deposit. After using the initial spins, deposit and spend £10 on eligible Daily Jackpot or Jackpot King games to receive a further 50 free spins. All winnings from both batches are paid as withdrawable cash with no wagering requirement attached.
Can I deposit at Betfair using cash?
Yes. Because Betfair and Paddy Power are on the same PPB Entertainment UKGC licence, Betfair customers can deposit cash into their online account at any Paddy Power shop. Paddy Power operates more than 600 betting shops across the UK and Ireland, making this one of the more accessible cash deposit options available at any major online bookmaker.
