How We Rate

Our Review Methodology at Ostengolf

At Ostengolf, every review you read on ostengolf.co.uk is the product of a structured, hands-on evaluation process carried out by James Wilson. Our mission is simple: to give UK players honest, thorough, and independent assessments of non Gamstop betting sites so they can make genuinely informed decisions. This page explains exactly how we work, what we look for, and how we keep our ratings free from operator influence.

Who Reviews the Sites

James Wilson is the author and owner of Ostengolf. With years of experience in the UK gambling industry and a deep understanding of the offshore and non Gamstop market, James personally registers an account, makes real deposits, places real bets, and tests customer support on every site before writing a single word of a review. No site is rated based on operator-supplied information alone. If James has not tested it firsthand, it does not appear on this website.

Our Step-by-Step Review Process

Each review follows the same sequence to ensure consistency and fairness across all listings.

• Step 1 – Initial Research: James researches the operator's background, ownership structure, licensing jurisdiction, and any publicly available regulatory history before signing up.
• Step 2 – Account Registration: A real account is created using standard UK player details to evaluate the sign-up process, identity verification requirements, and any friction points.
• Step 3 – Deposit Testing: A real deposit is made using multiple payment methods where possible to assess processing times, fees, and security.
• Step 4 – Gameplay and Betting: James places real wagers across sports betting markets and casino games to evaluate odds quality, game variety, software performance, and overall user experience.
• Step 5 – Bonus Claiming: Welcome bonuses and promotions are claimed and their terms and conditions are read in full, with particular attention paid to wagering requirements, time limits, and withdrawal restrictions.
• Step 6 – Customer Support Testing: Live chat, email, and where available telephone support are contacted with genuine questions to measure response times, accuracy, and helpfulness.
• Step 7 – Withdrawal Request: A withdrawal is requested to test payout speed and any additional verification steps imposed by the operator.
• Step 8 – Mobile Testing: The site or app is tested on a mobile device to assess layout, loading speed, and functionality.
• Step 9 – Scoring and Writing: All findings are compiled into a structured score and a written review that reflects the real experience, not a sanitised version of it.

How We Score Each Site

Every site is scored on a scale of 1 to 10, where 1 represents a poor, potentially unsafe operator and 10 represents an exceptional all-round experience. The final score is a weighted average calculated across six core criteria.

How Ostengolf Stays Unbiased

Independence is the foundation of everything we publish. Ostengolf may earn affiliate commissions when a reader signs up to a site through our links. However, this commercial arrangement never influences our scores or editorial content. James Wilson applies the same criteria and the same level of scrutiny to every operator regardless of whether they have a commercial relationship with Ostengolf.

Sites are not permitted to pay for higher ratings, request edits to published reviews, or have any input into the scoring process. If a site improves or deteriorates after our initial review, James revisits it and updates the score accordingly. Our readers come first, and that principle does not change.

If you have questions about how a specific site was reviewed or scored, or if you believe information in a review is inaccurate, you are welcome to contact James Wilson directly through the contact page on ostengolf.co.uk.
