About SisterBrand

SisterBrand is an independent research publication that maps the corporate ownership structures behind UK-licensed online casino and betting brands. We trace operator networks through Gambling Commission licence records, Companies House filings, payment infrastructure analysis, and cross-jurisdictional corporate registry data. The result is a resource that helps players understand which companies are actually responsible for the gambling brands they use.

We do not publish advertiser-funded rankings. We do not accept payment for placement. The casinos featured on this site are independently selected based on licensing status, operator transparency, payout reliability, and player protection standards. Our editorial decisions are not influenced by commercial relationships.

Two casinos can look completely different and still share the same parent company, the same operating licence, the same payment processor, and the same dispute resolution record. In a regulated market like the United Kingdom, where the Gambling Commission holds operators accountable at the corporate level, understanding these ownership structures is one of the most effective ways to assess whether a brand meets your standards for safety and reliability.

A casino review tells you what one brand looks like from the outside. A sister site analysis tells you what company is actually behind it.

Every operator profile on this site follows a four-layer verification process. We check the Gambling Commission's public register to verify licensing status. We trace corporate ownership through Companies House and equivalent registries in other jurisdictions. We review the operator's compliance history, including any enforcement actions, advertising rulings, and dispute resolution records. And we verify payment infrastructure to identify shared corporate connections between brands.

We do not rely on operator self-reporting as a primary source. When we cite a corporate fact, it is traced to a public record. When we cannot verify a claim through independent sources, we say so.

All content on SisterBrand is written by researchers with direct experience in UK gambling regulation, corporate due diligence, and player protection policy. We do not use AI-generated content for editorial analysis. Every page is reviewed for factual accuracy before publication and updated when market conditions, licensing status, or corporate ownership structures change.

We distinguish clearly between verified sister site relationships (confirmed through licensing, ownership, or corporate disclosure) and recommended comparison options (comparable brands that are not owned by the same company). When we do not have sufficient evidence to confirm a sister site relationship, we say so explicitly rather than filling the gap with unverified claims.

Every editor on this site works under the same editorial standard: no payment for placement, no advertiser influence on ratings, and no sister site connection published without independent verification through at least two public sources.
