Methodology: how we choose operators, collect facts and calculate the score
Bookie Ledger compares betting sites that appear on the GRAI licence register. We read primary sources only, record a source page and date for every cell, and calculate the Ledger score from published weights. We do not place bets or open accounts. The methodology is version 1.0, dated 7 November 2026.
How do we choose operators?
We start from the GRAI licence register, filtered to business-to-consumer entries. Only a remote betting (RB) licence qualifies an operator for the matrix. Intermediary (RBI) entries are handled separately.
Brands without a register entry on the day are logged as “not found on the date” with no conclusion. The reasons for every entry are in the inclusion log.
Operator names in our tables are candidates, and each licence is to be confirmed on the register on the day of publication.
Bottom line: The register decides who is in; everything else follows.
How do we collect facts?
We read the operator's public pages and its terms, then record the page address, a quote of up to 25 words, the date and a snapshot hash. Where a figure comes from the law or the regulator, we cite that primary text.
We did not place bets, open accounts or deposit money. We do not test speed of payment or app quality, and we do not publish odds.
A cell we could not read is marked “Not verified”, and one the operator's page did not state is marked “Not published”.
Bottom line: Every cell has a source page and a date; nothing comes from tests.
How is the Ledger score calculated?
The score, WS-1 version 1.0, has 19 indicators in five groups with weights adding up to 100: licence and transparency 20, safer-gambling controls 25, payments and withdrawals 20, markets and product 20, support and complaints 15.
A missing or unreadable item scores zero, and we do not call that a fault in the service. An operator with more than three unverified indicators stays in the matrix but leaves the ranking.
Equal scores share a place and are listed alphabetically. The score measures what operators publish, not odds or service quality. See the comparison matrix for cells and the sensitivity test for the effect of other weights.
Bottom line: The score is a sum of published points, recalculated from the same cells.
How often is it updated?
| Data family | Check | Extra trigger |
|---|---|---|
| Licence and register entry | Day of publication and weekly; limit 30 days | Entry removed or GRAI news: operator removed at once |
| Settlement rules | Weekly; limit 7 days | New edition of the rules |
| Payments and limits | Monthly; limit 30 days | Change to the payment page |
| Safer gambling and support | Every 90 days | Change to tools or help numbers |
| Markets and menu | Every 90 days | Change to the menu |
| Ledger score | Recalculated on the first Monday of each month | Change to any input fact |
A figure past its check date is hidden or marked until it is rechecked. Changes to published terms are logged in the terms change tracker.
Bottom line: Settlement rules are rechecked weekly; the score is recalculated monthly.
