William Hill Sister Sites

Operated by Evoke plc (formerly 888 Holdings plc), incorporated in Gibraltar (registration 90099), listed on the London Stock Exchange · Last reviewed: 2026-07-05

William Hill Sister Sites: The Full Evoke plc Network Explained

William Hill is one of the most recognised betting brands in the United Kingdom, with a retail and online presence stretching back decades. Since 2022, however, it has operated as part of a larger corporate group. Evoke plc — the company formerly known as 888 Holdings — acquired William Hill's European and UK operations from Caesars Entertainment for approximately £1.95 billion. That acquisition brought William Hill into a portfolio that already included 888casino, 888sport, 888poker, 777 Casino and Mr Green, making Evoke one of the largest regulated online gambling operators in the UK market. Understanding what a sister site actually means in the context of William Hill is important before exploring the individual brands. The term is used in two distinct ways in the industry. In the strictest regulatory sense, a sister site shares the same UKGC operating account as its sibling — meaning one entity holds responsibility for multiple products under a single licence number. In the broader commercial sense, sister sites are brands that share a common parent company but may hold independent UKGC licences. William Hill's situation reflects the second model: its online product is operated by WHG (International) Limited under a separate UKGC account from 888 UK Limited, which runs 888casino, 888sport, 888poker and 777 Casino. Mr Green, meanwhile, is operated through a further distinct entity, Blue Rock Managed Services Ltd, for its UK-facing activities. This article covers all verified brands within the Evoke plc group that accept UK players.

Who Owns William Hill?

William Hill's parent company is Evoke plc, incorporated in Gibraltar with registration number 90099 and listed on the London Stock Exchange. Evoke completed its acquisition of William Hill's European operations in July 2022, folding the brand into a wider portfolio that originated from the 888 Holdings business. Evoke retains a UK Companies House overseas establishment reference of FC039377. As of mid-2026, Bally's Intralot — an Athens-listed gaming technology provider — reached an agreement to acquire Evoke in a deal valued at approximately £243 million, though that transaction remained subject to regulatory approval at the time of this review and had not closed. The practical significance of Evoke's group structure for UK players is that several meaningful consumer protections are applied at group level rather than brand level. This includes a cross-brand self-exclusion system, shared KYC infrastructure and coordinated anti-money-laundering processes. However, each UKGC licence entity remains independently responsible for its own compliance obligations, which is why UKGC enforcement actions have been issued against multiple Evoke entities separately rather than against the group as a whole.

William Hill's UKGC Licence Structure

William Hill's online operation is run by WHG (International) Limited, which holds its own UKGC remote operating account. William Hill Organization Limited holds a separate non-remote operating licence covering retail activity. These are distinct entities with distinct regulatory records. The WHG (International) Limited entity was issued with a £12.5 million penalty in March 2023 as part of a combined £19.2 million UKGC regulatory settlement covering three Evoke group entities. That settlement found failures between May 2020 and October 2021 in safer gambling and anti-money-laundering processes, including a specific finding that 331 customers who had self-excluded from Mr Green were still able to gamble at WHG-operated sites during that period. William Hill Organization Limited received a separate regulatory payment of approximately £2.999 million in relation to retail compliance failings, alongside a £6.2 million UKGC fine issued in February 2018 for systematic failures to prevent money laundering. The UKGC stated in 2023 that it gave serious consideration to licence suspension before agreeing the settlement terms.

Verified Sister Sites of William Hill

The five brands listed below are confirmed Evoke plc group brands that accept UK players. All have been cross-referenced against Evoke corporate disclosures, UKGC public register entries, and third-party research. Licence numbers are only stated where a primary source has been identified; where no primary-source URL confirms the exact number, this review states 'Not publicly confirmed' rather than risk quoting an inaccurate figure.

888casino

888casino is the flagship online casino brand within Evoke plc and is operated in the UK by 888 UK Limited under its own UKGC account. The brand also holds licences from the Malta Gaming Authority and the Gibraltar Betting and Gaming Association, qualifying it as a dual-licensed operator from a UK player perspective. The UK lobby features over 2,000 games across slots, jackpot titles, table games and a live casino section powered exclusively by Evolution Gaming. 888casino also benefits from in-house content produced by Section8 Studios, which develops exclusive titles for the Evoke network. Withdrawals are routed back to the original deposit method in line with UKGC source-of-funds requirements, typically processing within 24 to 48 hours once internally cleared. A notable structural point for UK players is that 888casino, 888sport and 888poker share a single wallet and operate under the same 888 UK Limited UKGC account. This means an existing 888casino customer can access 888sport's sportsbook and 888poker's poker client without registering separately or undergoing a second KYC check. Games are independently audited by eCOGRA. 888 UK Limited has received multiple UKGC financial penalties, including a £9.4 million package in 2022 for social responsibility and anti-money-laundering failings, further penalties in August 2024, August 2025 and November 2025 for credit card breach violations and self-exclusion process errors. These are matters of public record on the UKGC website and should form part of any player's due diligence.

888sport

888sport is Evoke's dedicated sportsbook, covering over 30 sports including football, horse racing, tennis and a wide range of in-play markets. It operates under the same 888 UK Limited UKGC account as 888casino and 888poker, so UK customers who hold an 888 account already have access to the sportsbook without re-registration or additional identity verification. The shared-wallet arrangement means balances are accessible across all three products simultaneously. 888sport has its own promotional schedule, which runs independently of the casino side and includes accumulator-focused offers and in-play betting boosts. A dedicated mobile app is available alongside the desktop platform. Because 888sport sits within the 888 UK Limited account, it is subject to the same compliance history as 888casino — including the 2022 penalty package and subsequent fines. Players who are already verified at any 888 product will find sports betting available immediately through the same account dashboard.

888poker

888poker traces its origins to the Pacific Poker brand launched in 2002, making it one of the longer-established online poker rooms in the UK market. It operates alongside 888casino and 888sport under 888 UK Limited's UKGC account, meaning the shared wallet and single-account structure applies here too. The platform offers cash games at various stake levels, sit-and-go formats and a schedule of multi-table tournaments including larger guaranteed prize pools. For players who want to remain within the same verified-account environment as their William Hill account — while exploring skill-game poker rather than casino or sports betting — 888poker represents the most direct route within the Evoke portfolio, since the underlying group infrastructure is shared even though separate accounts are technically required between WHG-operated products and 888 UK Limited products. 888poker is integrated into Evoke's group-wide self-exclusion propagation system, meaning any exclusion applied at William Hill will extend to 888poker automatically since April 2023.

777 Casino

777 Casino is a retro-themed online casino operating within the 888 UK Limited stable. It shares the same in-house operator platform and UKGC account as 888casino, making it a true same-licence sister within the 888 network — distinct from William Hill and Mr Green, which sit on separate UKGC entities. The game catalogue is slots-heavy and smaller in scope than 888casino's full lobby, targeting players who prefer a classic, simplified casino experience over an extensive multi-category platform. The Vegas-style aesthetic and focused slot selection make it a different proposition to William Hill's hybrid sports-and-casino offering. Because 777 Casino shares the 888 UK Limited licence, it sits within the same self-exclusion propagation system and responsible gambling infrastructure as the broader Evoke group. Players who have been verified at 888casino do not need to complete a fresh KYC process to access 777 Casino under normal circumstances, though individual account registrations are still required.

Mr Green

Mr Green is positioned as the premium online casino brand within the Evoke portfolio and has an atypical recent history that UK players should understand clearly. The brand temporarily exited the UK market in October 2024, when its UKGC remote casino licence for certain activities — held by Mr Green Limited — was surrendered. It subsequently relaunched as a casino-only platform under a Playtech licensing arrangement, with UK-facing activities conducted through Blue Rock Managed Services Ltd, a Gibraltar-based Evoke group entity. The relaunch excluded sports betting, positioning Mr Green exclusively as a casino and bingo product for UK customers. The brand accepts UK deposits from £5 and maintains its own UKGC-facing compliance structure independent of 888 UK Limited and WHG (International) Limited. In March 2023, Mr Green Limited was fined £3.7 million as part of the combined £19.2 million UKGC settlement described above — the same settlement that penalised WHG (International) Limited and William Hill Organization Limited. Despite these corporate changes, Mr Green remains integrated into Evoke's group-wide self-exclusion system, so any exclusion applied at William Hill or any other Evoke brand propagates to Mr Green automatically.

Licence and Safety Review

All five brands listed in this article hold or operate under a UKGC-facing regulatory structure. William Hill's WHG (International) Limited, 888 UK Limited and Blue Rock Managed Services Ltd are each independently responsible for their own compliance obligations. This fragmented licence structure is more demanding to enforce than a single-entity group licence, but it also means each brand must independently meet UKGC standards — including financial crime controls, safer gambling requirements and player fund protection obligations. However, a High safety index does not mean a clean regulatory record. As documented above, multiple Evoke entities have received significant UKGC financial penalties between 2018 and 2025. Players should weigh this record when deciding how much trust to extend to any Evoke group brand.

Cross-Brand Self-Exclusion and Responsible Gambling

The UKGC's 2023 enforcement action specifically identified a failure in Evoke's earlier self-exclusion processes: 331 customers who had applied for self-exclusion from Mr Green remained able to gamble at WHG-operated sites, including William Hill. This finding directly prompted Evoke to introduce a group-wide internal self-exclusion propagation system in April 2023. Under that system, a self-exclusion request made at any Evoke group brand — William Hill, 888casino, 888sport, 888poker, 777 Casino or Mr Green — is automatically propagated to all related accounts identified across the group from the point of activation. Players experiencing difficulty controlling their gambling should contact GamCare (gamcare.org.uk) or the National Gambling Helpline on 0808 8020 133, both of which are free and available around the clock. BeGambleAware (begambleaware.org) also provides support tools and referral pathways.

Bonuses: What to Expect Across the Network

Each Evoke brand operates its own independent promotional calendar. William Hill's welcome offer is available only to new WHG (International) Limited account holders. Registering at 888casino, 888sport, 888poker, 777 Casino or Mr Green involves opening a separate account with a different operating entity, which may — subject to that brand's current terms — qualify as a new customer eligible for that brand's welcome promotion. However, Evoke's group-wide KYC pipeline means that sequential registrations across multiple group brands are likely to trigger identity verification checks. Players should anticipate providing identity documents at each separate brand rather than assuming prior verification transfers automatically between WHG and 888 UK Limited entities, as these are distinct licence holders. Bonus terms across all Evoke brands change frequently; the specific welcome offers summarised in the site listings below should be verified directly on each brand's website before registration. Wagering requirements, minimum deposit thresholds, eligible games and time limits vary by brand and can be updated without notice.

Payment Methods and Account Management

William Hill supports a range of UK deposit and withdrawal methods including debit cards, PayPal and bank transfer, in line with UKGC requirements that prohibit credit card gambling. Withdrawal timelines vary by method but are subject to the same UKGC source-of-funds requirements that apply across all licensed UK operators. 888casino processes withdrawals back to the original deposit method within 24 to 48 hours once internally cleared, as noted in its own terms. Payment method availability at 888sport, 888poker, 777 Casino and Mr Green should be confirmed directly on those sites, as each entity maintains its own cashier. Because William Hill (WHG) and the 888 UK Limited brands are separate UKGC entities, there is no shared wallet or unified balance between William Hill and 888casino, 888sport or 888poker. A player holding £50 in their William Hill account cannot access that balance from the 888casino lobby. Transfers between group brands require withdrawing to a payment method and re-depositing at the destination brand. This is a practical point that distinguishes the Evoke group from operators who run multiple products on a single account with a truly portable wallet.

Mobile Access

William Hill offers both a dedicated mobile app and a mobile-responsive website for UK players. 888sport and 888poker both operate dedicated mobile apps alongside their desktop clients. 888casino, 777 Casino and Mr Green offer mobile-responsive browser experiences; dedicated app availability should be confirmed on each brand's site as this can change with operating system updates and app store policies. The quality of mobile experience varies across Evoke's portfolio, with William Hill and 888sport generally regarded as the most developed mobile sportsbook products in the group.

How William Hill Compares to Other Large UK Operators

Evoke's portfolio is large by UK market standards, but it is not the only major operator group with multiple consumer-facing brands. Players researching UK betting options might also want to review how rival network operators compare — for instance, the Bet365 sister sites page covers the structure of that operator's related brands, while the Ladbrokes sister sites article outlines the Entain group's UK portfolio, which competes directly with William Hill across retail and online markets. Understanding operator networks across the industry helps UK players make informed decisions about where they hold accounts and how self-exclusion or bonus eligibility rules interact across groups. For players specifically interested in exchange-based betting or the Flutter Entertainment group, the Betfair sister sites guide provides a comparable breakdown of that network. Independent bookmaker groups are covered by resources such as the Betfred sister sites article, which is relevant for players who prefer a single-operator brand without the complexity of a multi-entity corporate structure.

Sites Excluded from This List

This article only includes brands with a confirmed and current Evoke plc corporate relationship and active UK-facing operations. Historical Evoke brands that have exited the UK market, ceased trading or been sold to third parties are not listed, as including them could mislead players about where they can currently open an account. Where a brand's UK regulatory status changed during the review period — such as Mr Green's temporary exit and subsequent relaunch — this is documented in the individual brand summary rather than used as a reason for exclusion, provided the brand was actively accepting UK players at the time of this review's last update in July 2026.

Verdict

William Hill's position within Evoke plc gives UK players access to a broad portfolio of related brands covering sports betting, online casino, poker, live tables and a simplified slots-focused experience via 777 Casino. That said, Evoke's regulatory record across its various entities is one of the more extensive penalty histories among major UK operators, spanning multiple UKGC financial sanctions between 2018 and 2025. Players who value a clean compliance record above all else may weigh this carefully. From a practical standpoint, the licence split between WHG (International) Limited, 888 UK Limited and Blue Rock Managed Services Ltd means that opening accounts at multiple Evoke brands does not provide wallet portability or automatic bonus eligibility — each brand must be treated as a genuinely separate product with its own registration, identity verification and promotional terms. This is standard for large multi-entity operator groups, but it is worth setting out plainly so players are not surprised by the process. All brands covered here are confirmed Evoke group members, all hold current UKGC-facing operating authority, and all are subject to the same national self-exclusion infrastructure that applies across the entire UK licensed market.
