How We Rate Casinos
At Harmony Mediation, we've developed a comprehensive methodology to evaluate online casinos and bingo platforms operating in the UK market. Our ratings are designed to help players make informed decisions about where to play safely and responsibly. Below, we outline the key criteria we assess, listed in order of importance.
Licensing & Regulation
Player safety is our top priority. We verify that casinos hold valid licences from reputable regulatory bodies, with particular emphasis on:
- UKGC (UK Gambling Commission) – The primary regulator for UK-based operators
- MGA (Malta Gaming Authority) – A respected international licence holder
- Local GB Licence – Direct licensing under UK jurisdiction
- Curaçao eGaming – Additional international regulatory compliance
We check licence validity, compliance history, and any enforcement actions. Casinos without appropriate UK licensing receive significantly lower ratings.
Game Selection & Software Providers
A quality casino offers diverse gaming options from reputable software providers. We evaluate:
- Slot Games – Variety, RTP (Return to Player) rates, and game quality
- Live Casino – Live dealer games, streaming quality, and table limits
- Table Games – Blackjack, roulette, baccarat, and other traditional offerings
- Software Providers – Partnerships with industry leaders such as NetEnt, Microgaming, Playtech, and Evolution Gaming
We assess the breadth of titles, fairness certifications, and overall gaming experience quality.
Bonus Terms & Wagering Requirements
We scrutinise welcome bonuses and ongoing promotions to ensure fair play:
- Terms & Conditions – Clarity, transparency, and fairness of bonus rules
- Rollover / Wagering Requirements – Realistic multipliers (typically 30x to 50x for fair offers)
- Maximum Cashout Limits – Whether caps apply to bonus winnings
- Restriction Conditions – Games excluded from bonus play, time limits, and withdrawal restrictions
We flag casinos with predatory bonus terms or hidden clauses.
Payment Methods & Withdrawal Speed
Convenient and secure payment options are essential. We review:
- Payment Methods – Debit/credit cards, e-wallets (PayPal, Skrill, Neteller), bank transfers, and cryptocurrency options
- Withdrawal Speed – Time to process payouts (same-day to 5+ business days)
- Deposit Limits – Minimum and maximum transaction amounts
- Security – Encryption standards and fraud prevention measures
We prefer casinos offering multiple withdrawal methods and rapid processing times.
Customer Support
Responsive and helpful support is crucial for player satisfaction. We assess:
- 24/7 Live Chat – Availability and response times
- Email Support – Response quality and time to resolution
- Phone Support – Whether available and during which hours
- FAQ & Knowledge Base – Comprehensive self-service resources
- Responsiveness – Thoroughness of answers and problem-solving ability
We test support channels and evaluate staff professionalism and knowledge.
Mobile Experience
With most players gaming on mobile devices, we evaluate:
- Responsive Design – Website compatibility across phones and tablets
- Dedicated Apps – Native iOS and Android applications
- Game Performance – Speed, stability, and visual quality on mobile
- Navigation – Ease of use and account management on smaller screens
- Payment Processing – Mobile-friendly deposit and withdrawal systems
We test both browser-based and app-based experiences on various devices.
Responsible Gaming Tools
Protecting vulnerable players is essential. We verify implementation of:
- Deposit Limits – Daily, weekly, and monthly spending caps
- Self-Exclusion – Ability to voluntarily ban oneself from the platform
- Cooling-Off Periods – Mandatory breaks from play
- Reality Checks – Session time warnings and reminders
- Problem Gambling Resources – Links to support organisations such as GamCare and National Problem Gambling Clinic
- Account Closure – Easy account closure options
We assess ease of access to these tools and prominence of responsible gaming messaging.
Our Rating Scale
We rate casinos on a scale of 1 to 10, where:
- 9–10 (Excellent) – Outstanding across all criteria. Fully licensed, generous but fair bonuses, excellent support, robust responsible gaming tools, and superior user experience.
- 7–8 (Good) – Strong performance in most areas. Reliable licensing, decent game selection, fair terms, and responsive support. Minor areas for improvement.
- 5–6 (Fair) – Meets minimum standards but with notable shortcomings. May have restrictive bonus terms, limited payment methods, or inconsistent support quality.
- 3–4 (Poor) – Significant concerns. Questionable licensing, unfair terms, weak customer service, or insufficient responsible gaming protections.
- 1–2 (Unacceptable) – Unlicensed, fraudulent, or posing serious player safety risks. Not recommended under any circumstances.
Our ratings are updated regularly to reflect changes in casino operations, new regulations, and player feedback. We remain independent and do not accept payments from casinos for inflated reviews.
