What they tell their suppliers
In their own words · from the filing
Standard payment terms
Our standard payment terms are 30 days. Our wholesale payments are paid in accordance with market terms.
Dispute resolution
Our Accounts Payable team keep track of any disputes daily. A full list is escalated to Heads of Departments weekly to progress resolution.
Other information
Of the payments made during the reporting period, 13% were not paid within terms. Excluding invoices in query or those in dispute this reduces to 3% (Sep 2025: 4% to 2%). Paid within terms decreased marginally to 97% (Sep 2025: 98%). Due to a technical issue, two invoices totalling £3.8million were paid one day late which significantly increased the value of late payments in the period.

What a 26-day cycle ties up
A worked example, not a finding. On a hypothetical £12k/month account, at a 26-day vs a 6-day payment cycle.
Late Payment Act. The Late Payment of Commercial Debts (Interest) Act 1998 lets a supplier charge statutory interest and fixed compensation on invoices paid past agreed terms. Work out what a late invoice is worth → Whether it applies depends on your contract — check with an adviser.

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).
