We are a small team of experienced betting analysts providing honest, independent reviews of non GamStop betting sites for UK punters. No pay-to-play rankings. No borrowed content. Just real-money testing and transparent journalism.
Bookmaker100 exists for one reason: to provide independent, honest, and genuinely useful reviews of non GamStop betting sites for UK punters. The offshore betting landscape is growing rapidly, and with that growth comes a flood of low-quality review sites that prioritise affiliate commissions over reader trust. We set out to be the antidote to that problem.
Our mission is straightforward. We want every UK bettor who visits our site to walk away with a clear understanding of which non GamStop bookmakers are trustworthy, which ones to avoid, and exactly why we have reached those conclusions. We believe that transparency is not optional — it is the foundation of any review site worth reading.
We do not sugarcoat our findings. If a bookmaker has slow withdrawals, limited customer support, or questionable licensing, we say so. If a site excels in a particular area — whether that is competitive football odds, fast crypto payouts, or a well-designed live betting interface — we highlight that too. Our readers deserve the full picture, and that is what we deliver.
Beyond reviews, we produce comprehensive betting guides covering everything from football betting strategy to understanding odds formats. We also maintain detailed informational resources on topics like GamStop self-exclusion and responsible gambling, because we recognise that operating in this space carries a duty of care to our readers.
Bookmaker100 is run by a small team of experienced betting analysts, payment specialists, and content professionals with over 40 combined years in the UK gambling industry. We are not a faceless content farm. Every member of our team has a verifiable background in the industry, and we put our names to the content we publish.
Our team has worked across the gambling sector in various capacities — from odds compiling at UKGC-licensed operators to fintech compliance and sports journalism. This breadth of experience means we can evaluate bookmakers from multiple angles: the quality of their odds, the security of their payment infrastructure, the responsiveness of their support, and the fairness of their terms and conditions.
We are based in the United Kingdom and write exclusively for a UK audience. Every review, guide, and recommendation on this site is produced with UK punters in mind. We understand the specific challenges that UK bettors face when dealing with offshore bookmakers — from payment processing quirks to currency conversion fees — because we deal with those same challenges every time we test a new site.
Importantly, we are completely independent. We are not owned by, affiliated with, or controlled by any bookmaker, gambling operator, or gambling industry body. Our reviews are our own, our ratings are based on our own testing, and our recommendations reflect our own honest assessments.
At its core, our work involves three things: real-money testing, transparent methodology, and monthly updates.
Every bookmaker featured on Bookmaker100 has been tested with genuine deposits and real bets. We do not rely on demo accounts, press releases, or marketing materials. Our testing process involves depositing our own funds, placing bets across multiple sports and markets, engaging with customer support, and — most importantly — withdrawing our winnings to measure payout speeds and identify any friction in the process.
This approach is expensive and time-consuming, but it is the only way to provide reviews that genuinely reflect the user experience. A bookmaker might look brilliant on paper but fall apart when you actually try to withdraw your funds. We find out so that our readers do not have to.
We publish our full review methodology on our How We Review page. Every site is assessed against the same criteria, using the same scoring system, by reviewers who follow the same testing protocols. This consistency ensures that our ratings are comparable and meaningful.
We score bookmakers across five key areas: licensing and security, odds and markets, payment methods, bonuses and promotions, and user experience. Each area is weighted according to its importance to the average UK punter, and the final score reflects a balanced assessment of the overall offering.
The non GamStop betting landscape changes constantly. Bookmakers adjust their bonus offers, add or remove payment methods, change their terms, and sometimes close entirely. We re-test our featured sites on a rolling basis and update our reviews monthly to ensure that the information on our site remains accurate and current.
If a bookmaker that we have previously recommended deteriorates in quality — whether through slower payouts, reduced market coverage, or poor customer support — we will downgrade their rating and flag the change prominently. Conversely, if a site improves, we will update their review to reflect that improvement.
Three values underpin everything we do at Bookmaker100:
We are an affiliate website, and we earn commission when readers visit bookmakers through our links. We are completely transparent about this. However, our editorial decisions are never influenced by commission rates. We have declined to feature bookmakers that offered generous affiliate terms but failed our testing standards, and we have prominently recommended sites that pay modest commissions but deliver excellent user experiences. Independence means that our readers' interests always come first.
We publish our methodology, name our reviewers, disclose our affiliate relationships, and explain our reasoning. If we rate one bookmaker higher than another, you can read exactly why. We do not hide behind vague language or undisclosed criteria. We believe that transparency is the only way to earn and maintain reader trust.
We review non GamStop betting sites, but we never encourage irresponsible gambling. Every page on our site includes links to support organisations like GamCare and BeGambleAware. We maintain a comprehensive responsible gambling guide and encourage all readers to set budgets, take breaks, and seek help if gambling stops being enjoyable.
We recognise that some people use non GamStop sites to circumvent self-exclusion. We do not encourage this behaviour, and we urge anyone experiencing gambling-related harm to contact the National Gambling Helpline on 0808 8020 133.
The non GamStop review space is crowded, and frankly, much of what is out there is poor quality. Here is what sets Bookmaker100 apart:
We do not claim to be perfect. Reviews involve subjective judgement, and reasonable people can disagree about the relative importance of different factors. But we do claim to be honest, thorough, and genuinely independent — and we stand behind every review we publish.
Our small but experienced team brings together expertise in sports betting analysis, payment security, compliance, and sports journalism. Each member plays a distinct role in our review process, and together we ensure that every piece of content on Bookmaker100 is accurate, fair, and genuinely useful.

Sarah brings 8 years of experience in fintech and gambling compliance to the Bookmaker100 team. She specialises in payment processing, cryptocurrency transactions, and platform security — areas that are critically important when evaluating offshore bookmakers.

She reviews every bookmaker's payment methods, tests deposit and withdrawal processes across multiple channels, and assesses the security protocols that protect user data and funds.
Sarah also leads our compliance reviews, checking licensing credentials, terms and conditions, and data protection practices against industry standards.
