About Us

Betting Not On Gamstop is an independent research site for adults in Great Britain and the wider UK who want to understand betting sites not on GamStop before they sign up. We read the terms, compare the offers and explain the risks in plain English. Our focus is bookmakers with free bets, so we pay particular attention to the small print behind each bonus.

Fact-check date: 1 October 2026. Bonus terms, payment options and licensing details change often, so always confirm them on the operator's own site before you deposit.

Who we are and what we publish

This site publishes reviews and guides on non GamStop sports betting. Topics include how odds work, welcome bonuses, free bets, wagering requirements, payments, withdrawals, sports markets, bet types and mobile betting apps. We use fractional odds in our examples and pounds sterling for illustrative amounts.

No author is named on this page. The content is produced by the site's editorial team. We don't claim credentials we can't show.

Commercial disclosure

We may earn a commission if you click a link to a bookmaker and sign up. That is how the site is funded. Commission does not buy position: ranking is based on our editorial assessment, and an operator cannot pay for a higher place or a better write-up.

What "not on GamStop" actually means

GAMSTOP is the free national self-exclusion scheme for online gambling in Great Britain. Operators licensed by the UK Gambling Commission must take part in it. A site "not on GamStop" is usually licensed overseas instead. That means it is generally outside UK Gambling Commission oversight and the consumer protections that come with it.

Accepting British customers is not the same as being authorised to serve them. If a bookmaker is not UKGC-licensed, you may have limited routes for complaints, and protections such as mandatory GAMSTOP checks will not apply. If you have registered with GAMSTOP because gambling was causing you harm, using these sites undermines that decision. Please read our responsible gambling guide first. Free, confidential help is available from GamCare.

How we research and rank bookmakers

We have not bought, deposited with or withdrawn from these sites for our ratings. Our assessments come from reviewing each operator's published terms, licensing statements, payment pages and advertised offers. Where we can't verify something, we say so.

1. Licensing information: which regulator the operator states, and whether we could verify it.
2. Bonus terms: wagering requirements, minimum qualifying odds, expiry dates, maximum bonus bets and cashout limits.
3. Payments: GBP account availability, debit card, e-wallet, bank transfer and crypto options, fees, currency conversion and withdrawal limits.
4. Betting range: football, horse racing, tennis, darts, snooker, esports and more, plus in-play betting, bet builders and cash-out.
5. Support and complaints: contact channels, the complaints procedure and the verification (KYC) process.
6. Tools: deposit and loss limits, self-exclusion and account controls.

Our ratings are editorial scores. They are not customer-review scores.

Reading a free bet offer properly

A headline figure tells you little. A free bet usually returns winnings only, not the stake. A bonus described as "100% up to £100" may need a qualifying deposit and be subject to wagering before you can withdraw. As an illustration, a £20 bonus with 10x wagering means £200 of qualifying bets. Odds of 1/1 or longer might be required, and the bonus might expire after a set number of days.

Several of the offers we feature are quoted in euros or dollars. If your account is not in GBP, currency conversion fees may apply. Check this before you deposit.

How the featured bookmakers differ

The ranked list above shows the current headline offers. The differences below come from those offers only.

• Tenobet is ranked first, with a sports package of 300% up to €3,000. The limitation is that the offer is in euros, so conversion costs and a large wagering requirement are worth checking.
• smash advertises 250% up to €5,000. Large percentages usually come with heavier wagering, so read the conditions before you claim.
• Betninja offers €1,000 plus 100 free spins. The spins are casino-style, so they may matter less if you only want sports free bets.
• WinnerIsland promotes up to 55% on accumulators with Multiboost. It is aimed at acca bettors and is not a standard free bet.
• Gamble Gorilla offers 100% up to £100 with a £20 deposit. The amount is in sterling, but it requires a deposit, so it isn't a free bet in the strict sense.
• Rolletto pairs a 150% sports bonus with a 200 free bet offer. Check how the free bet is credited and how long it lasts.

Other operators on our list, including CoinPoker, Gambiva, BetBluff and 7abet, are compared in our rankings. Always confirm each operator's licence and terms yourself.

Casino and sportsbook sections

Many of these brands run a casino alongside their sportsbook, sometimes with a shared wallet. Bonus rules and wagering contributions can differ between the two. Our separate guide to non GamStop casinos covers that side.

Protecting yourself

• Set deposit and loss limits before you start, and keep to them.
• Expect identity and source-of-funds checks before withdrawals.
• Never bet money you need for essentials. Betting is not a source of income.
• Gambling blocking software and GAMSTOP can help if you want to stop.

You must be 18 or over. No site is completely safe, and withdrawals are never guaranteed.
