In their own words · from the filing

Standard payment terms

Normally 30 days from receipt of invoice (>80% of suppliers have these payment terms)

Dispute resolution

Disputes with suppliers over payment terms are relatively rare. Almost all delays in payment of invoices (when these occur) relate to obtaining appropriate approvals and sign-offs. Where disputes do arise, these are resolved with discussions between finance, the relevant department purchasing the product or services, and the supplier themselves.

Working-capital effect

What a 13-day cycle ties up

Illustrative. On a hypothetical £12k/month account, at a 13-day vs a 0-day payment cycle.

≈ £5,000
of invoicing outstanding at any one time on a 13-day cycle — about £5,100 more than the same account would carry at 0-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).
