1. The 8 Criteria and Their Weights
These are the betting site rating criteria, with the weights they carry. They sum to 100 and are published so that a reader can reconstruct any score on the site.
| Criterion | Weight % | What we check | How we test | 10/10 means | 0/10 means |
|---|---|---|---|---|---|
| Licence & regulation | 20 | Licence held for UK customers, GamStop participation, named dispute service, funds protection statement, safer-gambling tools | Licence number read against the Gambling Commission public register or the offshore regulator’s own validator; dispute route and funds statement read in full; tools switched on from a live account | Gambling Commission licence, active status, domain listed, GamStop participation, UK adjudicator named, funds protection stated | No verifiable licence for UK customers, which triggers exclusion rather than a low score |
| Odds & margin | 15 | Match-result pricing on Premier League and top European football, racing concessions, whether Best Odds Guaranteed applies and from what time, daily caps on it | Prices on the same fixtures compared across the operators on our list at the same moment; BOG terms, caps and qualifying markets read against the operator rules | Consistently among the tightest match-result pricing on our list, with BOG on all UK and Irish racing and no restrictive cap | Consistently the widest pricing on our list, with no concessions of any kind |
| Bonus terms | 15 | Minimum deposit, minimum odds, wagering, expiry, maximum win, whether the stake returns, excluded payment methods | The offer claimed on a real account and the terms audited clause by clause against a fixed checklist, then the free bets used through to settlement | No wagering, a low minimum-odds threshold, a generous window and no payment method locked out | Heavy wagering, a short window, a capped win and most payment routes excluded |
| Withdrawal speed | 15 | Processing time published per method, minimum withdrawal, whether identity checks must clear before the first payout, closed-loop rules | A withdrawal requested on every method the site accepts from a funded account, confirmed as received, and scored against the window the operator publishes for that method | Same-day payout on cards and e-wallets, a low minimum withdrawal and no surprise pending period | Multi-day payouts on every method, a high minimum and identity checks only raised at the payout stage |
| Payment methods | 10 | Debit cards, PayPal and other e-wallets, Apple Pay, Google Pay, Pay by Bank, prepaid, bank transfer, plus fees and limits | Each available method used for a deposit from a UK account, then a withdrawal attempted back through the same route; fees and limits read from the operator’s own banking page | A broad UK-relevant set including at least one e-wallet, no fees, and low minimums both ways | Debit card only, fees on either direction, or methods advertised that a UK customer cannot use |
| User support | 10 | Channels offered, hours, whether a human is reachable, and whether the answer is correct | The same scripted questions on bonus terms and payout timing sent through every channel the operator offers | Every channel answers, a human is reachable, and the answer matches the published terms | No reachable channel, or answers that contradict the operator’s own terms |
| Functionality | 10 | In-play speed, live streaming scope, cash out type, Bet Builder selection limits, app availability on iOS and Android | Bets placed in play under peak weekend traffic, cash out taken, Bet Builder pushed to its selection cap, apps used on both platforms | Fast in-play, broad streaming, full and partial cash out, a deep Bet Builder and apps on both stores | No in-play, no cash out, and no app on either platform |
| Reputation signals | 5 | Brand history, regulatory record, transparency of terms | The public record and the operator’s published terms read against what the account actually did | A long record, a clean regulatory history and terms that match the marketing | A record of enforcement action, or terms that contradict the advertised offer |
The order of the weights is deliberate. Licence and regulation carries the most because it decides whether a reader has anywhere to go when a payout stalls, and no feature elsewhere in the product compensates for its absence. Pricing and bonus terms come next because they are what a bet actually costs. Functionality and reputation carry least, not because they do not matter, but because a fast app is worth little behind a licence you cannot verify. These bookmaker review criteria are the same eight published on our homepage, in the same order and under the same names.
Two rules sit above the table. An operator with no verifiable licence for UK customers is excluded automatically and is never given a score, however good the rest of its product is. And the licence criterion is tiered rather than binary: a Gambling Commission licence takes full marks, a strong international regulator such as the Malta Gaming Authority scores in the middle because it protects players seriously but gives no UK legal cover and no GamStop access, and a Curaçao or Anjouan licence takes a low baseline because the dispute route behind it is narrow.
2. How a Review Is Produced, Step by Step
This is how we test betting sites, in the order it happens. Each step is carried out on a live account by the reviewer whose name appears on the review.
- Licence and register check. We take the licence number from the operator’s footer and read it against the Gambling Commission public register, confirming the status is active and the domain is listed. For an offshore operator we use that regulator’s own validator instead. A failure here ends the process.
- Registration and identity checks. The reviewer registers as a UK customer with their own details and completes verification, noting whether it clears automatically and how long it takes.
- Deposit. We deposit the minimum the operator allows, using the method the welcome offer requires, and record the time to credit and any fee.
- Betting. We place a set of bets across pre-match and in-play markets, including at least one Bet Builder or accumulator, and take a cash out where the feature exists.
- Withdrawal. We request a withdrawal on every method the site accepts and confirm the funds arrive, checking the result against the processing window the operator publishes for that method.
- Support. We send the same three scripted questions through every channel the operator offers and compare the answers against its published terms.
- Scoring and sign-off. The reviewer scores all eight criteria, then a second reviewer or the responsible editor checks the score and the balance of the review before it can be published.
- Publication and re-review. The review goes live with the reviewer’s name, and offers, terms and licence records are re-checked every month. Each review is rebuilt from scratch once a quarter and the score recalculated across all eight criteria.
Two points about that sequence are worth stating plainly. Nobody scores a bookmaker they have not held an account with, and no score reaches the site without a second person signing it off. The rules governing who may write and who approves are in our Editorial Policy.
3. How the Final Score Is Calculated
The arithmetic is a weighted sum. Each criterion is scored from 0 to 10, multiplied by its weight, and the results are added and rounded to one decimal place. There is no adjustment afterwards and no editorial discretion applied to the total.
Here is a worked example for a hypothetical bookmaker, using the weights from the table above.
| Criterion | Weight % | Criterion score | Contribution |
|---|---|---|---|
| Licence & regulation | 20 | 10 | 2.00 |
| Odds & margin | 15 | 8 | 1.20 |
| Bonus terms | 15 | 7 | 1.05 |
| Withdrawal speed | 15 | 9 | 1.35 |
| Payment methods | 10 | 8 | 0.80 |
| User support | 10 | 6 | 0.60 |
| Functionality | 10 | 9 | 0.90 |
| Reputation signals | 5 | 8 | 0.40 |
| Final betting site score | 100 | — | 8.3 |
Ties happen, and the order is decided rather than left to chance. Where two bookmakers land on the same score, the higher licence tier goes first. If both hold the same tier, and on our main ranking they always do, the faster payout takes the higher position. If they are level on both, the earlier position goes to the operator whose welcome offer carries fewer conditions.
4. What Can Change a Rating After Publication
A score is a snapshot of an operator, not a permanent judgement, and these are the things that move it between scheduled re-reviews.
- A licence change: a lapse, suspension or new regulator changes the first criterion immediately and can remove the operator from the site;
- A regulatory sanction or formal enforcement action against the operator;
- A change to the welcome offer or its conditions, including wagering, minimum odds or excluded payment methods;
- The removal or addition of a payment method that UK customers rely on;
- A change in published payout windows, or a payout that does not arrive within them on our own account;
- Our own scheduled re-test, which rebuilds the review from scratch once a quarter.
Rating updates triggered by any of the first five are applied as soon as we have verified them, rather than waiting for the quarterly cycle.
5. What Does Not Affect a Rating
Commission has zero weight in this methodology. The size of an affiliate payment, whether a commercial relationship exists at all, and how much an operator spends on advertising are not inputs to any of the eight criteria, and there is no ninth criterion where they could hide.
Nor can a bookmaker buy its way up. A partner cannot purchase a ranking position, a score, a softer set of cons or the removal of a drawback. Operators with no commercial relationship with us appear in the same lists, in the same order of merit, judged on the same eight criteria by the same reviewers, and several of the Gambling Commission licensees on our main ranking are there on exactly that basis. Unbiased betting site ratings are not a claim we can prove with adjectives, which is why the weights, the anchors and the arithmetic are all on this page.
How the site is funded, including the affiliate redirects behind our outbound operator links, is set out in How We Make Money.
