What they tell their suppliers
In their own words · from the filing
Standard payment terms
Severn Trent Water’s standard payment term for new contracts is 60 days (or 30 days for businesses with less than 50 employees); this applies across all contracts raised and would be agreed with suppliers prior to the commencement of the trading activity. On occasion, authorisation may be granted to reduce the payment terms below 60 days if there is commercial requirement/benefit in doing so. Such a change requires approval from the Commercial team. We would not attempt to impose payment terms longer than 60 days on any of our suppliers, nor do we use early settlement discounts as part of contractual arrangements.
Dispute resolution
If communication between the purchaser and supplier fails to resolve the dispute, the Severn Trent Commercial or Finance team will engage with the supplier and the business user to bring about a resolution.

What a 40-day cycle ties up
A worked example, not a finding. On a hypothetical £12k/month account, at a 40-day vs a 15-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).
