Last updated: May 2026 — James Whitfield, Completely K9
Every betting site review published on Completely K9 is the result of a structured, hands-on evaluation carried out by site owner and lead reviewer James Whitfield. This page explains exactly how that process works, what criteria are assessed, how scores are calculated, and why you can trust the ratings you find here to be honest, independent, and genuinely useful to UK bettors in 2026.
We do not accept payments from operators to influence our scores. We do not publish reviews based on press releases or marketing materials. Every rating on this site reflects real testing, real money, and real experience.
Before any testing begins, James checks whether the operator holds a valid licence issued by the UK Gambling Commission (UKGC). If a site is not licensed to operate in Great Britain, it is not reviewed. This is a hard requirement with no exceptions. James also checks for responsible gambling tools, self-exclusion options, and compliance with UKGC advertising standards.
James personally registers a new account using his own details, completing the full Know Your Customer (KYC) verification process. This allows him to evaluate how smooth, quick, and transparent the onboarding experience really is for a first-time user.
Where a welcome offer is available, James claims it and reads the full terms and conditions carefully. He pays particular attention to wagering requirements, minimum odds restrictions, time limits, and any clauses that could make an offer less valuable than it first appears.
James uses the betting site across multiple sessions on both desktop and mobile devices. He places real bets across several sporting markets, tests the cash-out function, navigates the casino section where available, and evaluates loading times and overall usability.
A real deposit and withdrawal are completed during every review. James records how long the withdrawal takes to arrive and notes any fees, restrictions, or complications encountered along the way.
James contacts the customer support team at least twice per review — once via live chat and once via email. He evaluates response time, accuracy of information, and overall helpfulness.
Once all testing is complete, James applies the scoring framework below, writes up his findings in plain English, and publishes the review. No operator sees the review before it goes live.
Each betting site is scored out of 10 in six categories. Those category scores are then weighted to produce a single overall rating out of 10, which appears at the top of every review.
| Category | Weighting | What We Assess |
|---|---|---|
| Licensing and Safety | 25% | UKGC licence status, responsible gambling tools, data security, fair terms |
| Bonuses and Promotions | 20% | Welcome offer value, ongoing promotions, wagering requirements, transparency of terms |
| Game and Market Selection | 20% | Range of sports markets, in-play betting, odds competitiveness, casino content where applicable |
| Payment Methods | 15% | Deposit and withdrawal options, processing speeds, fees, minimum and maximum limits |
| Customer Support | 10% | Availability, response times, quality of answers, support channels offered |
| Mobile Experience | 10% | App quality or mobile browser performance, ease of navigation, feature parity with desktop |
