BestSisterSites.co.uk is an independent gambling comparison and review site. We research, review and compare online casinos, betting sites and bingo sites to help UK players make informed decisions about where to play. This editorial policy explains how we produce our content, how we decide which operators to feature and the standards we hold ourselves to.
Editorial Independence
Our reviews, ratings and recommendations are based on our own research and assessment. No operator can pay to influence the outcome of a review, alter a rating or guarantee a favourable comparison. Our editorial decisions are made independently of any commercial relationship.
BestSisterSites.co.uk earns revenue through affiliate commissions when readers click through to an operator and register an account. This commercial model is standard across the gambling comparison industry. However, the presence or absence of an affiliate relationship does not influence how we rate, review or rank any operator. For full details on how affiliate commissions work, please see our Disclaimer.
How We Research and Review
Every sister site listing and operator review on this site is produced through a consistent research process. We assess operators across the following areas:
Licensing and regulation: We verify that every operator featured on the site holds a valid licence from the UK Gambling Commission. Operators without a current UKGC licence are not reviewed or recommended. We check licence status directly through the UKGC public register and update our records regularly.
Ownership and corporate structure: We identify the parent company, holding group or operating entity behind each brand to establish accurate sister site relationships. This information is sourced from UKGC licence records, Companies House filings and operator websites.
Game selection and software: We review the range of games available including slots, table games, live dealer and speciality titles. We note the software providers used and whether the game library is proprietary or supplied through third-party aggregators.
Bonuses and promotions: We assess welcome offers, ongoing promotions and loyalty programmes. All bonus information is verified against the operator’s current terms and conditions. We make every effort to keep bonus details current but these change frequently and readers should always check the operator’s site for the latest terms.
Payment methods and withdrawal times: We review the deposit and withdrawal options available to UK players including processing times, minimum and maximum limits and any fees.
Customer support: We assess the availability and quality of customer support channels including live chat, email and telephone.
Responsible gambling tools: We review the responsible gambling tools and features each operator provides, including deposit limits, loss limits, session time reminders, cooling-off periods and self-exclusion options.
Accuracy and Updates
We are committed to keeping our content accurate and up to date. The gambling industry changes frequently – operators launch new brands, change ownership, update bonus terms and occasionally lose or surrender their licences. We review and update our content on a rolling basis to reflect these changes.
If you spot an error in any of our content, please contact us with details of the page and the issue. We investigate all reported errors and publish corrections promptly where warranted.
Content We Will Not Publish
BestSisterSites.co.uk does not publish content that promotes unlicensed gambling operators to UK players. We do not publish content that encourages underage gambling or presents gambling as a way to make money or solve financial problems. We do not publish misleading claims about the likelihood of winning or the nature of gambling outcomes.
