In their own words · from the filing
Standard payment terms
For the majority of our supplier contracts, payment terms are 30 days from date of invoice.
Dispute resolution
Where a dispute occurs, it is first broached by the person who raised the order, and they liaise with the supplier. If they need further support, it can be escalated to the head of department level. If further escalation is then required, our Legal department is consulted.

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).
