Last updated: June 2026 — Daniel Ashworth, Griffin Carpentry
Every casino review published on griffin-carpentry.co.uk is the result of a structured, hands-on evaluation process carried out by Daniel Ashworth. This page explains exactly how that process works, what criteria matter most, and why you can trust the scores you see across this site. There are no shortcuts, no copy-pasted information from operator press releases, and no scores awarded without genuine testing.
Daniel Ashworth is the author and owner of Griffin Carpentry. Daniel personally tests every non-UK casino featured on this site before a single word of a review is written. That means creating a real player account, navigating the registration process, making deposits using genuine payment methods, playing a selection of games, and contacting customer support directly. Only after completing this hands-on process does Daniel begin writing a review and assigning scores.
Daniel has been evaluating online casinos available to players in Great Britain since the early 2020s, with a specific focus on operators licensed outside the UK Gambling Commission framework. This specialisation means the criteria applied here reflect the genuine concerns of GB-based players who choose to play at non-UKGC-licensed sites in 2026.
Before anything else, Daniel confirms the casino holds a valid licence from a recognised international authority. If a site cannot demonstrate legitimate licensing, it does not receive a review. This is a hard filter with no exceptions.
Daniel registers a real account and documents the entire sign-up experience, including how long verification takes, what documents are requested, and whether the process is straightforward for a player based in Great Britain.
Real deposits are made using payment methods commonly available to GB players. Withdrawal requests are submitted and the processing times are recorded. Any fees, delays, or complications are noted in full.
Daniel plays a representative selection of slots, table games, and live casino titles. The quality of software providers, game loading speeds, fairness certifications, and the overall depth of the game library are all assessed.
Welcome offers and ongoing promotions are read in detail, including the full terms and conditions. Wagering requirements, eligible games, maximum bet rules, and withdrawal caps are all recorded and scored against industry standards.
Daniel contacts the support team through at least two available channels, typically live chat and email, asking both straightforward and more complex questions. Response times and the quality of answers are documented.
The casino is accessed via a mobile browser and, where available, a dedicated app. Navigation, game performance, and the ease of completing account tasks on a smaller screen are all evaluated.
Once all testing is complete, Daniel assigns scores across each category and writes the review based solely on what was observed during the testing period.
Each casino receives an overall score out of 10. This score is a weighted average calculated from six individual category scores. The table below shows each category and its contribution to the final rating.
| Category | Weighting |
|---|---|
| Licensing and Safety | 25% |
| Bonuses and Promotions | 20% |
| Game Selection | 20% |
| Payment Methods | 15% |
| Customer Support | 10% |
| Mobile Experience | 10% |
Griffin Carpentry earns revenue through affiliate commissions when readers sign up to a reviewed casino. This is standard practice in the industry and allows the site to operate without charging readers. However, commercial relationships never influence scores or written conclusions. Daniel applies the same methodology to every casino regardless of whether an affiliate agreement exists. Casinos that score poorly are published with honest scores. Casinos that fail the licensing check are not reviewed at all, regardless of the commission on offer.
No operator has editorial input into any review on this site. Scores are not shared with casinos before publication. Operators cannot pay to improve their rating or remove a negative assessment.
The online casino landscape changes. Licences expire, bonus terms change, and game libraries grow or shrink. Daniel revisits published reviews on a regular basis to ensure the information remains accurate and relevant for GB players reading in 2026 and beyond. Where material changes are identified, reviews are updated and the revision date is noted.
