Last updated: June 2026 — Richard Thornley, Thamesteel
At Thamesteel, every non-UK casino review published on thamesteel.co.uk is the product of a rigorous, hands-on evaluation process carried out personally by Richard Thornley. This page explains exactly how that process works, what criteria are assessed, and how we arrive at the scores you see alongside each casino listing. We believe UK players deserve transparent, honest guidance when exploring offshore gaming options, and that starts with showing our work.
Richard Thornley conducts every review personally. With years of experience analysing the online gambling industry and a specific focus on offshore and non-UK-licensed casinos, Richard brings both technical knowledge and practical player perspective to every evaluation. He creates real accounts, makes actual deposits using his own funds, claims bonuses, plays games, contacts customer support, and tests withdrawal processes before writing a single word of a review. No review on Thamesteel is written based on operator-supplied information alone or from behind a desk without genuine play.
Before registering at any casino, Richard researches the operator's history, ownership structure, licensing jurisdiction, and any publicly available player complaints. Sites with a history of unresolved payment disputes or predatory practices are removed from consideration at this early stage.
Richard registers a genuine player account using standard UK credentials. The registration process itself is evaluated for clarity, speed, and the reasonableness of identity verification requirements.
This is the core of the process. Richard deposits real money, claims any available welcome bonus, plays a representative sample of games across different categories, and tests the full withdrawal process including any required documentation. Support channels are contacted with genuine queries to assess response quality and speed.
After testing is complete, each criterion is scored individually according to the weighting system described below. Richard then writes the review in full, and the final score is calculated before publication.
Published reviews are revisited periodically. Casinos are re-evaluated when significant changes occur, such as a licence update, new ownership, altered bonus terms, or a pattern of emerging player complaints. Scores are updated accordingly and revision dates are noted on each review page.
Each casino is scored out of 10 in six key categories. A weighted final score is then calculated to produce the overall Thamesteel rating.
| Category | Weighting | What We Assess |
|---|---|---|
| Licensing and Safety | 25% | Jurisdiction of licence, regulatory reputation, SSL security, responsible gambling tools, data protection practices |
| Bonuses and Promotions | 20% | Welcome offer value, wagering requirements, bonus terms fairness, ongoing promotions, loyalty scheme quality |
| Game Selection | 20% | Total game count, software providers, variety across slots, table games and live casino, game loading speed |
| Payment Methods | 15% | Deposit and withdrawal options available to UK players, processing times, fees, minimum and maximum limits |
| Customer Support | 10% | Available contact channels, response times, quality of answers, availability hours, language support |
| Mobile Experience | 10% | Browser compatibility on mobile devices, dedicated app availability, game performance on mobile, navigation ease |
All casinos are scored on a 1 to 10 scale in each category, where 1 represents very poor and 10 represents exceptional. The weighted final score also falls between 1 and 10. Here is how to interpret the overall ratings:
Thamesteel operates independently of all casino operators. Richard Thornley is not employed by, affiliated with, or financially directed by any casino brand reviewed on this site. While Thamesteel does earn referral commissions through affiliate links, this does not influence ratings or recommendations. Casinos are scored purely on merit, and poor scores are published without alteration regardless of any affiliate relationship. If a casino does not meet the standards our readers expect, it will not receive a recommendation, regardless of commercial considerations. Our readers come first, always.
If you have questions about how a specific casino was reviewed, or if you believe information on a review page is outdated, you are welcome to get in touch. Thamesteel is committed to accuracy, transparency, and maintaining a resource that UK players can genuinely trust when navigating the world of non-UK casinos in 2026 and beyond.
