How UK payment reporting works
What is a Payment Practices Report?
What does "paid outside agreed terms" mean?
How often is this data updated?
Is this official government data?
How this is compiled. Built from official records only: Companies House and the gov.uk payment-practices service. The payment figures are self-reported — companies over the size threshold must file them by law and the board signs them off. No credit-agency data. The numbers are theirs; the plain-English read is ours. This is information compiled from public records under the Open Government Licence v3.0 — not a credit rating and not advice.
The 31-day comparison figure is the median across 6,104 companies with a current statutory report — every sector pooled, not an average of sector medians (how the figure is built).
