What they tell their suppliers
In their own words · from the filing
Standard payment terms
Normally 30 days from receipt of invoice (>80% of suppliers have these payment terms)
Dispute resolution
Disputes with suppliers over payment terms are relatively rare. Almost all delays in payment of invoices (when these occur) relate to obtaining appropriate approvals and sign-offs. Where disputes do arise, these are resolved with discussions between finance, the relevant department purchasing the product or services, and the supplier themselves.

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).
