What they tell their suppliers
In their own words · from the filing
Standard payment terms
The most frequently used terms were 30 days from the end of the month in which the invoice is dated.
Dispute resolution
Payment disputes are handled by the Accounts Payable team, which liaises with the suppliers and the company’s buyers as necessary to resolve invoice and payment queries in a timely manner. Where correction of an invoice is necessary, payment is processed as soon as reasonably practicable following receipt of corrected invoice. The Accounts Payable team may be contacted via a dedicated Accounts Payable mailbox or by telephone.

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).
