This article explains what users typically mean when they ask about the williamhill app and why the term "sister site" matters. It focuses on how corporate ownership, licences and regulator records affect whether apps and accounts can be shared across brands. We use Evoke plc's public disclosures and UK Gambling Commission register entries as the authoritative sources for verification. The goal is a practical, step-by-step guide you can follow to confirm who operates an app or site and what that means for accounts and promotions.

Evoke plc lists William Hill alongside 888, Mr Green and Winner in its 2024 portfolio disclosures.

The UKGC Public Register is the authoritative place to check licence holders, trading names and domains for Great Britain.

Shared ownership does not automatically mean shared apps, logins or promotions for users.

What people mean by the williamhill app and why 'sister sites' matters

The phrase williamhill app is commonly used by customers to refer to William Hill's online betting interface, mobile presence and the credentials and offers tied to an online account. In everyday use, people also ask whether a different site is a "sister site" because they expect shared logins, common promotions or the ability to move account balances between brands; those expectations are exactly why the term matters for users.

For clarity, a concise definition helps: a sister site usually means two brands are owned by the same parent company or sit in the same corporate group, but this does not automatically mean they share apps, accounts or promotional entitlements. That distinction is important when you plan to sign in, transfer funds or rely on cross-brand offers.

Historically, corporate group structure explains why brands are called sisters. Evoke plc's 2024 rebrand and its multi-brand portfolio give a clear corporate reason some sites are grouped together; the rebrand and portfolio are documented in company disclosures and investor materials Evoke plc press release.

A few simple user expectations illustrate the gap between ownership and experience. Users often expect a single app, one login and pooled promotions; in practice, groups operate separate licences, distinct account databases and brand-specific terms and conditions. Verifying licence numbers and reading the operator terms is the quickest way to set realistic expectations before you sign up or deposit.

Common user questions about apps and sister brands

Common questions include: Can I use my William Hill login on a sister brand? Will promotions transfer across brands? Is the williamhill app the same as an app for another brand owned by the same group? Each of these questions depends on whether the brands share the same licence or explicitly provide account portability, not merely on corporate ownership.

How ownership and licences change the user experience

Ownership at the parent level creates governance and shared corporate functions, but licences determine who can legally operate accounts, accept deposits and offer promotions in a jurisdiction. That means two sister brands can look and feel similar while remaining legally and operationally separate for customers.

As of the most recent corporate disclosures, 888 Holdings plc rebranded to Evoke plc and lists William Hill among its group brands; this corporate-level change explains why William Hill appears alongside other brands in a common portfolio Evoke plc annual report.

According to Evoke's stated group portfolio, the principal sister brands disclosed by the group are 888 (casino, sport, poker), Mr Green and Winner. That portfolio listing is the primary public source for which brands the parent company describes as part of the same multi-brand strategy.

Evoke publishes a multi-brand strategy that keeps distinct consumer brands while aligning corporate functions such as risk, compliance and investor reporting. The result for users is familiar brand separation: William Hill may sit in the same corporate family as 888 and Mr Green, yet the customer-facing products remain brand-specific unless the operator explicitly announces integration.

For users of the williamhill app this matters because corporate ownership alone is not sufficient evidence that you can use one login across all group brands; account portability and app integration require explicit operator statements or licence consolidation to be reliable.

The rebrand to Evoke plc and the group's public reporting clarify which consumer brands are part of the parent, and these corporate disclosures are the quickest place to confirm whether a brand appears in the group's portfolio.

How licensing works in Great Britain: retail shops, online companies and the app

In Great Britain, legal operation often relies on separate licence holders for retail and online activity: William Hill's retail betting shops are licensed under William Hill Organization Limited, while online services operate under WHG (International) Limited. You can confirm these licence entries on the UKGC Public Register UKGC Public Register entry for William Hill Organization Limited.

The split between retail and online licences matters because the licence holder listed on the register is the legal operator for that channel; the online licence holder controls the app and the legal account terms for online customers. If you want to know which company is responsible for the williamhill app in Great Britain, the UKGC Public Register entry for the online operator is the authoritative source.

Check exact trading names and domains listed

The UKGC Public Register lists trading names and declared domains alongside the licence holder, which helps users match a website or app footer to the operator record. When a domain or trading name appears in the register, it is a strong indicator that the site is operated under that licence, and you can treat the operator's entry as the primary verification source.

Different legal entities for retail and online operations

Retail operations and online platforms often run under separate legal entities for regulatory, tax and operational reasons; that separation explains why an app and a shop with the same brand name may be controlled by different corporate subsidiaries or licence entries. Consult the exact company name in a site's legal or footer page and compare it to the UKGC listing to confirm who runs the app.

Where licence details appear on the UKGC Public Register

The UKGC Public Register shows the operator name, licence number, declared trading names and any domains the licensee registers. For Great Britain users trying to verify the williamhill app, matching the app's footer licence information to the UKGC entry is the pragmatic way to confirm which company legally controls the service.

Why shared ownership does not mean a shared app, account or promotions

Shared corporate ownership under a parent like Evoke plc does not automatically translate to shared logins, pooled accounts or universal promotions across brands; operational separation often persists because licences, regional rules and internal product strategies differ Evoke plc annual report.

Common legal reasons for separation include distinct licence obligations, jurisdictional restrictions and the need for separate customer due diligence. Operational reasons include different user databases, brand positioning and technical deployments that prevent easy account portability even when brands share a parent company.

From a user's perspective, this means you should not assume that a promotion or login available on one brand will be valid on another brand in the same group. Always check the specific terms and conditions and the licence number before assuming interoperability.

How brands stay separate for customers

Brands remain distinct through separate account systems, individual T&Cs and distinct marketing promises. Even when a parent group shares resources behind the scenes, the customer-facing experience can be entirely separate for account access and promotional eligibility.

Common legal and operational reasons for separation

Licence boundaries, differing regional permissions and separate technical stacks are typical causes for separation. If a group wanted to combine apps or accounts, it would usually announce a formal integration or licence consolidation; absent that, treat brands as operationally separate for customer account purposes.

Step-by-step: how to verify sister sites and apps yourself

Start your check with the parent company's public investor materials to see which brands the group lists in its official portfolio; the Evoke annual report is the central source for the group's declared brand list Evoke plc annual report.

Next, use the UKGC Public Register to confirm licence holders, trading names and listed domains for both the William Hill service you know and the candidate sister site. For example, search the register for the operator name and compare the site footer to the licence entry to confirm a match.

In the site's footer or legal page note the operator name, licence number and any stated trading names. If the footer lists a licence number or company name, compare those strings exactly with the UKGC entry fields. The match on operator name or domain is the evidence you need to treat a site as operated under the same licence.

Practical checklist items to use when you verify: 1) Confirm parent company portfolio in investor materials, 2) Search the UKGC Public Register for operator entries, 3) Match operator name, licence number and declared domains with the site's legal footer, 4) Read T&Cs to confirm account portability and promotion rules, and 5) When in doubt contact the operator's support for clarification. (See our blog post on how FundedPlays evaluations work how FundedPlays evaluations work.)

Check corporate disclosures from Evoke

Begin by checking Evoke plc investor pages and the annual report for the official list of brands; this tells you which brands the parent company publicly recognises as part of its portfolio and is the appropriate starting point for any sister site verification.

Use the UKGC Public Register to confirm trading names and domains

After confirming group ownership, search the UKGC Public Register for the licence holder named in the site footer. When the register lists trading names or domains that match the site you are checking, you can treat the site as operated under that licence for Great Britain users.

Decision criteria: when a site should be considered a William Hill sister site

Use a short checklist to decide whether a site qualifies as a William Hill sister site for your purposes. The checklist below ranks criteria by practical importance for users:

1) Shared parent company: Listed in Evoke's official portfolio is relevant background but not sufficient for account portability. 2) Shared licence holder: If both sites list the same licence holder and licence number on the UKGC register, they are operated by the same legal entity. 3) Shared trading name or domain on the register: Matching trading names or domains in the UKGC entry strongly indicate the same operator. 4) Explicit account portability statement: An operator statement or consolidated licence is the clearest evidence of shared accounts or a single app.

Which criteria matter depends on intent. For legal verification and regulatory complaints, the shared licence holder is the primary threshold. For account portability and promotions, an explicit operator statement or matching licence plus published account-transfer process matters most. If documentation is ambiguous, contact the operator or the regulator for confirmation.

Ownership vs licence vs brand use cases

Ownership indicates corporate control and group reporting, licence indicates legal operational authority and brand use indicates the user-facing product. For account control and app responsibility, treat licence information as decisive.

Practical thresholds for users

If you only need to know whether brands are related, the parent company's portfolio is sufficient. See the Funded Plays blog.

Common mistakes and pitfalls when checking for William Hill sister sites

A common mistake is equating similar branding or site design with identical operation; visual similarity does not substitute for licence verification. Always check the legal footer and the UKGC entry rather than relying on site appearance alone.

Relying on third-party lists or press stories without confirming official filings is another frequent error. Official sources to check are the parent company disclosures and the UKGC Public Register; these records show the legal operator and declared trading names and domains UKGC Public Register entry for 888 UK Limited.

False positives from shared branding

Assuming that similar logos, colour schemes or shared marketing means shared operation can lead to incorrect conclusions. The correct step is to match the footer company name and licence number with the UKGC record.

Overlooking licence differences

Failing to notice a different licence holder between retail and online channels or between jurisdictions is a frequent oversight. For Great Britain users, the UKGC Public Register is the authoritative source to check whether two sites share licence details.

Practical examples: checking 888, Mr Green and Winner as sister sites

Example 1, confirming 888: Start with Evoke's public reporting where the group lists 888 as a portfolio brand, then locate the UKGC entry for 888 UK Limited and compare its trading names and declared domains to the site you are checking Evoke plc annual report.

Are other sites like 888, Mr Green or Winner true William Hill sister sites and do they share the williamhill app?

Evoke plc lists 888, Mr Green and Winner as group brands, but shared ownership does not by itself mean a shared app or shared accounts; verify licence entries on the UKGC Public Register to confirm operational control and account portability.

Example 2, locating Mr Green: Look up Mr Green Limited on the UKGC Public Register and compare the register's trading names and domains to the Mr Green site footer to confirm whether the operational licence matches the brand you are evaluating UKGC Public Register entry for Mr Green Limited.

For Winner, use the same process: check the Evoke portfolio for inclusion, then search the UKGC register for the relevant licence entry and compare trading names and domains. A match on domain or declared trading name is the clearest indication the site is operated under the same licence in Great Britain.

Example 1: confirming 888 via Evoke disclosures and UKGC entries

The Evoke annual report names 888 among its consumer brands; use that corporate disclosure first, then corroborate with the UKGC entry for 888 UK Limited to see how the brand is licensed for Great Britain operations UKGC Public Register entry for 888 UK Limited.

Example 2: locating Mr Green on the UKGC Public Register

Search the UKGC Public Register for Mr Green Limited and compare the registered trading names and listed domains to the site you are checking. When the register lists the domain you see in the site footer, you can treat the operator entry as the authoritative confirmation of who runs the service.

Key takeaway: Evoke plc lists William Hill alongside 888, Mr Green and Winner in its public portfolio, which explains the corporate grouping of those brands; consult Evoke's investor materials for the official brand list Evoke plc annual report. (See Evoke Plc - licence summary Evoke Plc licence summary.)

Authoritative verification sources are the Evoke disclosures for ownership context and the UKGC Public Register for licence-level confirmation of which legal entity operates an app or site. For Great Britain users, match the operator name and declared domains in the UKGC entry to the site footer when you need to confirm legal operation.

Action checklist: check the Evoke portfolio, search the UKGC Public Register for the operator, match the site's footer to the register entry, read the T&Cs for account and promotion rules, and contact the operator if anything is ambiguous. Do not assume shared apps or promotions without explicit operator confirmation. Visit Funded Plays for related resources Funded Plays.

Can I use my William Hill login on a sister brand?

Not automatically. Shared corporate ownership does not imply shared accounts; only an operator statement or a shared licence guarantees login portability.

Where do I check if a site is operated by the same company as William Hill?

For Great Britain, use the UKGC Public Register to compare the operator name, licence number, trading names and declared domains with the site's footer.

Does Evoke ownership mean promotions are valid across all its brands?

No. Promotions and eligibility are governed by the licence and each brand's terms and conditions, not by parent company ownership alone.

If you plan to move money or link accounts across brands, always verify the licence information and read the operator's terms and conditions first. Re-check corporate disclosures and the UKGC Public Register before making decisions that affect your account or funds. When in doubt, contact the operator's customer support or the regulator for clarification; official records are the safest basis for decisions about accounts, apps and promotions.
