Methodology FAQ
How is 21.co.uk rated?
No overall IndexFair score is published for 21.co.uk in the United Kingdom. The publication state and evidence base are shown on this page. The required certification is not available.
Is 21.co.uk licensed in the United Kingdom?
21.co.uk 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 21.co.uk pay out?
No operator-stated processing window is available in this answer for 21.co.uk in the United Kingdom (methodology v2.1). No public payout-aspect projection is shown here for 21.co.uk. This does not establish that there are no payout-related signals in the evidence base. Withdrawal-delay complaint totals are not available in this answer.
What are 21.co.uk's weak points?
No public aspect projections are shown here for 21.co.uk. Their absence does not establish how much evidence is held.
Why are some scores low but the brand is still licensed?
A licence from UK Gambling Commission 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 21.co.uk's score come from?
The Sources section on this page lists the recorded sources for 21.co.uk and their contribution counts. These counts describe their own evidence scope; they are not an additional total for the overall score.
How often is 21.co.uk'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.
