The read · computed from their figures
Renewable Energy Systems Limited's H1 2026 filing puts their average at 82 days against stated terms of 30 days; 87% of invoices were paid outside agreed terms and 48% took 61 days or longer. Filed 22 May 2026.
The direction is slower: from 38 days in H2 2023 to 82 now — 44 days slower across their last 6 reports.
On the latest reported averages: Slower than 99% of the 394 large companies reporting in construction.
That is 17 statutory periods on record (earliest H1 2018) — a historical record, not a promise for a new invoice.
In their own words · from the filing
Standard payment terms
Renewable Energy Systems Ltd (“RES”) has standard payment terms of 30 days. If a supplier requests that RES complies with their standard terms and conditions and these contain payment terms which are different to 30 days, then, subject to Director approval, RES will adopt the supplier’s terms. There is no maximum contractual payment period within RES’s General Terms & Conditions of Purchase.
Dispute resolution
If at any time a dispute or difference arises between RES and the supplier in relation to or in connection with an accepted Purchase Order, both parties will aim to resolve the dispute through negotiation. If such dispute or difference cannot be resolved through negotiation, then either party may require the other party to give them notice in writing of the existence of such dispute or difference and at the request of either party, the same shall be referred to an Alternative Dispute Resolution (ADR) procedure as recommended to the parties.
Other information
Renewable Energy Systems Limited has undertaken a system migration during the six month period to 30 April 2026, causing temporary delays in the time taken to pay suppliers during this time. RES operates three payment runs each month and this can result in some invoices being paid later than the agreed payment period. Many of the 87% not paid within the agreed payment period is due to invoices that stated they were due for payment on presentation and as this is not practical, we do not believe it is a helpful statistic. If we were only to include those that were not paid within 30 days of receipt, this statistic would fall to 53%.

What a 82-day cycle ties up
A worked example, not a finding. On a hypothetical £12k/month account, at a 82-day vs a 30-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.

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).
