What they tell their suppliers
In their own words · from the filing
Standard payment terms
30 days of receiving a valid VAT invoice that is accurate, undisputed, and properly due.
Dispute resolution
Suppliers can contact the Accounts Payable team regarding payment queries at our Finance Service Centre via [email protected] or contact the ISS requisitioner, information is included on the Purchase Orders.
Other information
This entity solely engages with public sector work and therefore applies the statutory 30-day payment term implied under the Procurement Act 2023. We also follow a strict "no purchase order, no payment" policy. Unless an exception is formally approved by an authorised representative, any invoice submitted without a valid purchase order number will be rejected and returned to the supplier. To provide more detail on the total value of payments not paid within agreed period: £20,850,164 was Intercompany and £11,367,000 were due to a dispute.

What a 31-day cycle ties up
A worked example, not a finding. On a hypothetical £12k/month account, at a 31-day vs a 1-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 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).
