What they tell their suppliers
In their own words · from the filing
Standard payment terms
Payment terms are agreed with the supply chain as part of contract negotiations and comply with statutory and specific payment commitments on frameworks and or compliance with the Fair Payment Code. Agreed terms range between 7 and 60 days.
Dispute resolution
Tilbury Douglas is committed to treating its supply chain fairly and seeks to resolve any dispute as quickly as possible. Where a dispute arises with a supplier, this is sent to the finance team who seek to resolve the issue and where necessary consult with the procurement and or project team. Any disputes with Subcontractors are dealt with by the Project teams. In exceptional circumstances, the dispute may be referred to an executive director to resolve. Where appropriate the dispute resolution process in the contract terms and conditions will be followed.

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