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%.

Working-capital effect

What a 82-day cycle ties up

Illustrative. On a hypothetical £12k/month account, at a 82-day vs a 30-day payment cycle.

≈ £32,500
of invoicing outstanding at any one time on a 82-day cycle — about £20,500 more than the same account would carry at 30-day terms.

Late Payment Act. The Late Payment of Commercial Debts Act 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?
UK companies and LLPs above a size threshold — broadly, two of: turnover over £54m, balance sheet over £27m, or more than 250 employees — must report twice a year, under the Reporting on Payment Practices and Performance Regulations 2017, how quickly they actually pay suppliers: the average time to pay, the share of invoices paid in 30 days or fewer, 31 to 60 days and 61 days or longer, and their standard payment terms. Those thresholds apply to financial years beginning on or after 6 April 2025; for earlier financial years they were £36m and £18m, with the same 250-employee test.
What does "paid outside agreed terms" mean?
The share of invoices paid later than the terms in the supplier contract. If terms are 30 days and an invoice is paid on day 45, it counts as paid outside terms, regardless of the headline average.
How often is this data updated?
Each report covers a six-month period and must be filed within 30 days of that period ending, so a company's record refreshes roughly twice a year. PaidLate re-reads the register as new reports are filed.
Is this official government data?
The underlying payment figures come from the company's own statutory filings on the gov.uk payment-practices service; company-status data comes from Companies House. PaidLate calculates trends, comparisons and summaries from those records. It does not use surveys or credit-agency scores.

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 6,185 companies with a current statutory report — every sector pooled, not an average of sector medians (how the figure is built).
