Source categories — what feeds this score

Why this matters: Single-source review sites read very differently from the composite. Selection bias — only the loudest users self-report — is reduced here by aggregating across several sources. The category breakdown below shows the current mix and contribution without naming individual platforms. Methodology v2.1.

Methodology FAQ

How is William Hill rated?

William Hill’s overall IndexFair score is 4.8/10 — better than 5% of the United Kingdom sports betting brands. It is computed by the published formula — methodology v2.1. The evidence base on this page gives the collected and used counts and their scope.

Is William Hill licensed in the United Kingdom?

William Hill operates under a licence in the United Kingdom (current licence status on record: active). A licence reflects regulatory standing only — the IndexFair score adds user-experience and operational signals on top, so a licensed brand can still hold a low score.

How fast does William Hill pay out?

No operator-stated processing window is available in this answer for William Hill in the United Kingdom (methodology v2.1). On payout-related evidence, William Hill's overall-aligned public aspect projection is 4.7/10 (−0.1 vs overall), supported by 489 signals. Withdrawal-delay complaint totals are not available in this answer.

What are William Hill's weak points?

William Hill's lowest overall-aligned public aspect projection is KYC at 4.6/10 (−0.2 vs overall), supported by 158 signals. This is a counterfactual published score with the other blocks and market ruler held fixed, so it can differ from the overall score. The full breakdown is in the score section above.

Why are some scores low but the brand is still licensed?

A UK Gambling Commission licence reflects regulatory standing — the operator meets statutory and conduct requirements. The IndexFair score additionally aggregates recorded review, complaint and operator-response signals. A licensed brand can hold a low composite when those measured signals are weaker without amounting to a regulatory sanction. The methodology page details the per-block weights.

Where does William Hill's score come from?

The Sources section on this page lists the recorded sources for William Hill and their contribution counts. These counts describe their own evidence scope; they are not an additional total for the overall score.

How often is William Hill's score updated?

Scores recompute automatically whenever new review data, a licence-status change, or a methodology update arrives — typically within a few minutes, not on a daily schedule. Every brand card displays the 'last recomputed' timestamp. Methodology version changes are dated at /changelog.

What is the confidence interval?

The ±0.x bracket alongside a score is a 95% confidence interval derived from sample variance and effective sample size after time-decay. A score of 8.4 ± 0.3 reads as: 95% confidence that the true value lies in 8.1–8.7 given current evidence. Wider intervals indicate small samples or high source divergence between aggregators, not lower brand quality.

Can I trust this if it's automated?

The composite score is computed by a published formula, not editorial judgement — so the same inputs always produce the same output, and the formula is auditable. Methodology versions are append-only at /changelog with effective dates. Disputes route through /privacy/contact; the founder reviews factual disputes (licence status, regulator data). Aggregate review sentiment is not editable on a per-brand basis per source ToS.
